zoans, corals, brachiopods, mollusks andconodonts. SAKAGAMI (1972) was thefirst to recognize them as the Lower
Carboniferous. He described Mourlonia
and concluded that this gastropod isvery similar to the specimens from
Uzura, Akiyoshi Limestone (SAKAGAMI,
1973). Also, YANAGIDA (1973) describedseveral brachiopods and advocated thatthe fauna is apparently of Visean inage.
The purpose of the present paper is
to discuss geologic age and descriptionsof the conodonts from Mitsuzawa, Takimoto and Hossawa. These conodonts
are very important to settle the conodont biostratigraphy near the boundary
between the Lower and Middle Carboniferous of Japan. Detailed geologic observations of this district will be pre-

Geologic Setting
The Mitsuzawa Limestone outcrops
along a small valley in the south of
Mitsuzawa. The following succession
is measured along the Mitsuzawa Valley
in descending order.
Chert; thin-bedded, pale gray, green andpartly reddish .. more than 20 m thick.
Limestone; well-bedded, intercalating
thin layers of chert and dolomitic
layers .................... 9 m thick.
Chert; bedded, pale gray and reddish.......................... 7m thick.
Tuff; red, green and variegated, calcareous, intercalating nodular limestones and limestone layers, upper
part grades laterally into chert ....
.......................... 8m thick.
Tuff; red, partly variegated, intercala-413

ting thin layers of limestone in middle
part ...................... 15 m thick.
Both the upper and lower limits ofthis sequence are in contact with Triassic sediments by pronounced faults.
These lithologic units trend to N30·W
and dip 40· to the northeast. The lower
tuff is red, green and partly variegatedand becomes calcareous upward. The
calcareous part of this tuff comprises
fragments of crinoid stems, other calcareous materials and oolites. Nodular
shaped limestones are various in shape
but mostly subspheroid. Averaged diameter of them is about 30 cm. They
contain abundantly crinoid stems, corals,
bryozoans, gastropods, brachiopods andrarely goniatites. Fossils described by
SAKAGAMI (1973) and YANAGIDA (1973)
were collected from this level (158B in
Text-fig. 2). Limestones yielding corals
and bryozoans have almost the samelithology. The corals are Lithostrotion(Siphonodendron), Diphyphyllum and other
Rugosa. These corals are cemented
mostly by fine-grained lime mud, subordinate fossil fragments and detrital
calcite and partly filled with clear
sparry calcite. Brachiopodal and gastropodallimestones are highly bioclastic.
These fossils are cemented by fairly
large fragments of biogenetic calcite
which are mostly originated from
crinoid. Interstitial cement of clean
calcite is also recognized, and partly
interlocking these fragments of biogenetic calcite.
The upper limestone beds are almost
barren in megafossils except for small
fragments of crinoid and shells,. butthey contain smaller foraminifers andother microfossils. The lower part ofthis limestone is thin-bedded, laminatedand intercalating thin dolomitic layers.
This rock consists of fine-grained lime

414

mud with the admixture of smaller foraminifers and fragments of biogenetic
calcite which are mostly echinoderms.
Minute shell fragments in varying abundance are also recognized, but whatkind of fossil shells they represent isdifficult to determine. Small dolomiticrhombs are scattered in the particularlaminae as single individuals. These
components frequently show gradedlamination in a small scale.
The upper remainder of this limestone
unit intercalates chert layers of about
10 cm thick. Lithology of this part oflimestone is almost similar to the lower
part, but dolomitized and laminatedparts become obscure. Chert layersintercalated within this limestone aresometimes discontinuous and their upperand lower surfaces show irregular wavy
bedding plane.
The uppermost chert is thin-bedded,
about 5 to 10 cm thick, intraformationally folded, pale gray, green and partly
reddish. This chert unit yields abundant radiolarian remains and conodontsfrom the particular levels.
The above mentioned sequence of the
Mitsuzawa Valley can be traced laterally, but limestone thins abruptly both
northwest and southeast and is replacedby chert. At Takimoto, about 800 m
north of Mitsuzawa, this chert member
is about 40 m thick and intercalates
small limestone lenses or lentils. in thevarious levels. Erratics of limestone
derived from this member yield conodonts but are barren in megafossils.
Conodonts are well-preserved and more
numerous than the type section. Limeston~ at Takimoto may represent thecondensed sequence in contrast withthe biohermal or reef-like deposition at
Mitsuzawa.
. Further northwestern extension oflimestone occurs at Hossawa, the southof Mitake Railway Station. Limestonelayer interbedded with green chert,
about 10-15 cm in thickness yields numerous conodonts. These conodonts are
the same with those from the type section of the Mitsuzawa Limestone.

Appraisal of Conodont Fauna

Conodonts were recovered from 1 to
2 kg limestone samples by ordinary
acetic acid method. Samples embedded
in chert were observed by very thinslices and chips under the transmitted
light. Hydrofioric acid was supplementarily used for chert samples. All of thesamples shown in Text-fig. 2 are productive. The assemblage of conodont
does not show any remarkable difference
throughout the calcareous facies of themeasured section, but each species
varies in individual abundance.
The following species are discriminated from 158A through 158G, namely,
Cavusgnathus regularis YOUNGQUIST and
MILLER, Gnathodus bilineatus (ROUNDY),
Gnathodus commutatus (BRANSON and
MEHL), Gnathodus nodosus BISCHOFF,
Gnathodus sp., n. sp. (?), Ligonodina sp.,
Hindeodella spp., Ozarkodina sp.
Among them, Gnathodus bilineatus, G.
commutatus, and G. nodosus are predominant species. Gnathodus commutatusranges throughout the calcareous faciesof the measured section, but it is particularly abundant in the lower levels(158A, 158B, 158C). This well-known
species has been repeatedly describedfrom the Chesterian of North America(COLLINSON et al., 1971 and others) andthe Visean to Lower Namurian inGermany (MEISCHNER, 1970 and others),
Belgium (HIGGINS and BOUCKAERT,1968),
England (RHODES et al., 1969 and others)
and elsewhere. It is also present in the639. Carboniferous Conodonts from Itsukaichi

Nagoe Formation of the Atetsu Limestone (KOIKE, 1967), basal part of the
Akiyoshi Limestone Group (Hisaharu
IGo, 1973) and the lowest part of the Omi
Limestone (WATANABE, personal comm).
HAY ASH! (1971) reported the occurrenceof this species from the Permian Kuzuu
Limestone, Tochigi Prefecture and in-'sisted that the species survived into the
Permian in Japan. HAY ASH!'S identification, however, is apparently erroneousand his Gnathodus commutatus is a homeromorphic different species of Gnathodus (Hisayoshi IGo, 1972). Moreover,according to the authors' numerous unpublished data, this species never co-416

Hisayoshi leo and Fumio KOBAYASHI

exists with the typical lowermost Pennsylvanian species of conodont in Japan.
Therefore, the upper limit of this species
almost coincides with the case in Europe
and North America.
Gnathodus nodosus is also common in
the Mitsuzawa Limestone associatedwith Gnathodus commutatus. This species is abundant in 158A, 158B, 158C
and 158D and is rather sporadical inother samples. Gnathodus nodosus iswidespread in Europe, and it first appears from the Upper Visean and the
middle part of Cu mj3 and extinguishes
in the upper part of the Lower Namurian (E 2c). Typical Gnathodus nodosus bears one node on the uppersurface of both outer and inner sidesof the cup. Numerous specimens recovered from the Mitsuzawa Limestone
have some variations in the development of node on the cup. The nodesof the most of our specimens are morethan one and rather irregularly disposedcompared with the type species described from Germany (BISCHOFF, 1957).
Based on the specimens from the Griotteof Northwest Spain, HIGGINS (1962)
proposed Gnathodus commutatus multinodosus for this type of G. nodosus.
Therefore, the present ones are referable to G. multinodosus rather thanG. nodosus. This difference, however,seems to be continuous and the authors
reserved the validity of G. multinodosus.
Gnathodus bilineatus is also one of themost common species in the present
fauna, and it is yielded from 158A to
158G, but is particularly abundant in
158A, 158B, 158C and 158D. This species is a well-known species in theUpper Visean to Lower Namurian ofEurope and the Chesterian of North
America, and it has been known fromthe lowermost part of the Akiyoshi
Limestone, Omi Limestone and the

Nagoe Formation of the Atetsu Limestone in Japan. As will be discussed
later, the present specimens show considerable variation in the developmentof nodes.
Gnathodus sp. (n. sp.?) is rarely yieldedfrom 158A, 158D, 158E and 158G. This
species resembles Gnathodus dr. roundyi
GUNNELL described by KOIKE (1967)
from the Lower Pennsylvanian Kodani
Formation of the Atetsu Limestone. It
is also similar to Gnathodus roundyi
GUNNELL described from the Morrowanof USA by DUNN (1970). MERRILL (1972)
treated the mentioned species as a new
species and proposed Neognathodus medadulitimus MERRILL. Gnathodus girtyi
intermedius GLOBENSKY described fromthe. Windsor Group of Canada is slightly
related to the present Gnathodus sp., n.
sp. (?). It differs from GLOBENSKY'S(1967) Canadian subspecies in fusedcarina and other ornamentation of theplatform.
Cavusgnathus regularis is frequently
fragmental and rare in this section, but
it is rather common at Hossawa. This
species is known from the entire partof the Chesterian of North America.
The conodont fauna recovered from
the Mitsuzawa Limestone is apparently
equivalent to the fauna from the Chesterian of the North American Mississippian and also to the Upper Visean
to Lower Namurian of Europe. The
faunal aspect near the boundary between the Visean and Lower Namurianof Europe was discussed by HIGGINS(1961,1962,1967), HIGGINS and BOUCKAERT(1968), RHODES et al. (1969), BOUCKAERTand HIGGINS (1970) and others in Europe.
According to their studies, the Upper
Visean (V3c) or D3 is characterized by
Gnathodus bilineatus, G. girtyi girtyi, G.
girtyi collinsoni, G. commutatus, G. nodosus and others. The fauna of the639.

Carboniferous Conodonts from Itsukaichi

lowest Namurian (E2a) is poorly known
in Belgium but it comprises Gnathodus
bilineatus, G. girtyi and the first occurrence of Gnathodus noduliferus. The
faunas of E2b-E2c are characterizedby Gnathodus bilineatus, G. girtyi, G.
nodosus and G. commutatus. HIGGINS(1961) reported the Lower Namurian
conodonts from North Staffordshire,
England. These conodonts are almost
the same with the lower part of thetype Namurian in Belgium.
As cited above, there are no remarkable faunal change between the highest
Visean and the basal Namurian except
for questionable occurrence of Gnathodus noduliferus. Therefore, it is uncertain that the Mitsuzawa conodont
fauna indicates Upper Visean or Lower
Namurian.
However, the following
paleontological and stratigraphical evidence may allow to discuss more detailed correlation of the Mitsuzawa
fauna. Our present fauna is entirely
lacking Gnathodus girtyi and its subspecies which are rather common in
European Upper Visean.
Gnathodus
nodosus collected from the present section is multinodosus-type which is probably descendant modification of typical
G. nodosus. Some of our specimens
identified as Gnathodus bilineatus areslightly similar to G. bilineatus bollandensis HIGGINS and BOUCKAERT rather
than the typical G. bilineatus. G. bilineatus bollandensis was described from
E2b2, E2b3, E2c and HI of the type
Namurian.
SAKAGAMI (1973) and YANAGIDA (1973)
stated that their brachiopod-gastropod
faunas from 158B are equivalent to
the Yobara fauna of the Akiyoshi Limestone. Rich brachiopods from Yobara
were worked out by YANAGIDA (1962,1965) who concluded that the geologic
age is of Late Visean. IGO and KOIKE

417(1965) studied conodonts collected from
Yobara and they showed that the fauna
is apparently Lower Pennsylvanian orUpper Namurian. As will be discussed
later, the Mitsuzawa Limestone characterized by Gnathodus bilineatus, G. nodosus, and G. commutatus is conformably
overlain by chert which yielding apparent Lower Pennsylvanian or Upper
Namurian conodonts. From the above
mentioned evidence, we are inclined toconclude that the geologic age of the
Mitsuzawa Limestone is Late Chesterianof North America and Early Namurian
rather than Late Visean of Europe.
The other conodont fauna was foundin chert superposed above the Mitsuzawa Limestone in the type section.
The following conodonts are discriminated from 158H, 158J and 158P. These
include Gnathodus sp., n. sp. (?), Gondolella fujimotoi IGO and KOBAYASHI, n.
sp., Oxinagnathus corrugatus (HARRIS
and HOLLINGSWORTH), Gnathodus sp.,
Ozarkodina sp., and Hindeodella spp.
This fauna is quite similar to the faunafrom the calcareous facies of the upper
part of the Takimoto section.
Conodonts obtained from Takimoto
consist of two dissimilar faunas which
are derived from the different levels.
Unfortunately, however, precise stratigraphic relationship between twolevels is unknown. The older one wasrecovered from fine-grained gray limestone intercalated as the lentils in chert.
It has completely the same assemblageof conodont elements with the type section of the Mitsuzawa Limestone. The
same assemblage of conodonts is also
obtained from limestone layers interbedded with chert at Hossawa.
The younger fauna from Takimoto is
distinctive and consists of the following
species: Gnathodus nagatoensis IGO and
KOIKE, Gnathodus opimus IGO and KOIKE,418

Gnathodus Sp., Gnathodus cfr. bassleri

ldiognathodus sp., Oxinagnathus corrugatus (HARRIS and HOLLINGSWORTH),
Gondolella fujimotoi IGO and KOBAYASHI,
n. sp., Ozarkodina sp., and Hindeodellasp.
Oxinagnathus corrugatus is fairly
abundant in this fauna. This species
has been reported from the Lower Pennsylvanian Morrowan of North America(DUNN, 1970, etc.) and the Kinderscoutian (Rl) of the type Namurian ofBelgium (HIGGINS and BOUCKAERT, 1968;
BOUCKAERT and HIGGINS, 1970). Idiognathodus sp. is less common in the present

fauna and is similar to Idiognathodus
humerosus DUNN and I. parvus (DUNN)
which have been described from theupper part of the Morrowan in North
America. Gnathodus opimus and Gnathodus nagatoensis are rare in the present fauna, but they are characteristic species of the Yobara fauna of
the Akiyoshi Limestone (IGO and KOIKE,
1965). Gondolella fujimotoi is fairly
common and is related to Gondolella sp.
A described from the Kodani Formationof the Atetsu Limestone (KOIKE, 1967).
Recently, similar species, Gondolella
gymna, has been proposed by MERRILL
and KING (1971) from the Lower Pennsylvanian of Illinois, USA. Although
the specimens are fragmental, the occurrence of Gnathodus cfr. bassleri bassleri is noteworthy, because this species
is an excellent indicator of the Lower
Pennsylvanian in North America (LANEet al., 1972). This species is also rather
wide-spread in the Japanese Carboniferous associated with Eostaffella andother primitive fusulinaceans (Hisayoshi
IGo, 1972). The present fauna from Takimoto is unquestionably younger thanGnathodus commutatus-G. bilineatus-G.
nodosus fauna and is apparently similar
to the Morrowan of USA and Upper
Namurian of Europe.
In conclusion, the Carboniferous conodont fauna from the Itsukaichi district
comprises two distinct assemblages,
such as the older Gnathodus commutatus-G. bilineatus-G. nodosus fauna andyounger Oxinagnathus corrugatus-Idiognathodus sp. fauna. The former one
represents the majority of the Mitsuzawa Limestone and its equivalent at
Takimoto and Hossawa and is correlated
to the Lower Namurian and Upper
Chesterian. The latter fauna is foundin the upper chert beds of the typesection of the Mitsuzawa Valley and639. Carboniferous Conodonts from Itsukaichi
also in the calcareous facies of theupper sequence at Takimoto. This fauna
is considered to represent a part of theLower Pennsylvanian or Upper Namurian conodont faunas.

Remarks :-This species was fully described by MERRILL (1972). The present
forms are fragmentary and no complete
specimens are obtained. However, theircharacteristic ornamentation consistingof three longitudinal rows is distinct toidentify with Gnathodus bassleri bassleri.
DUNN (1970) proposed the genus Neognathodus with Polyghathodus bassleri HARRIS and HOLLINGSWORTH as its typespecies. He stressed that Neognathodus
bassleri evolved from Declinognathodus
lateralis (HIGGINS and BOUCKAERT) andhomeromorphic relation of Ganthodus
and Neognathodus. MERRILL and KING(1971) have questioned generic rank of
Declinognathodus but they treat Neognathodus as a distinct genus. ELLISON(1972), however, rejected the validity of
Neognathodus. We postponed to settle
generic problem herein.
Occurrence :-Rare in limestone distributed at Takimoto.

Remarks :-Our numerous specimens
are quite identical to the previously
described ones. There are, however,appreciable variations in the shape of
the platform and the disposition of thenodes on the outer lateral platform. In
some specimens, the nodes on the outer
lateral platform are irregularly disposed.
but in the other group these nodes havetendency of longitudinal linear arrangement. The former type somewhat resembles Gnathodus bilineatus bollandensis
HIGGINS and BOUCKAERT, but they bear
more numerous nodes than the Belgian
subspecies. However, the mentioned
variations are continuous, and there isno obvious difference among the specimens collected from various levels of
the present columnar sections.

Remarks :-As already noted by previous many authors, this species shows
considerable but continuous variation.
The specimens in the present collections
also show appreciable variations in thegeneral form of the platform, development of the carina and others. Thereis remarkable difference between thepresent and previously described onesin the lateral view of the carina.
Most of the specimens described bymany authors have high carina evenat the posterior end. The carina of thespecimens, however, gradually decline
posteriorly.

Rema1'ks :-Gnathodus nagatoensis was
originally proposed by IGO and KOIKE
as a subspecies of Gnathodus commutatus. Its important distinction is thelateral view of the cup and carina. Two
low nodes adjacent to the carina developed on the inner part of the cup in
the full growth specimens. Unit isgenerally thinly constructed comparedwith typical Gnathodus commutatus. The
authors are now inclined to believe thatthe mentioned differences have specificvalue rather than subspecific.
Occurrence :- Rare in chert superposed
above the Mitsuzawa Limestone andalso at Takimoto.

in general outline.
Inner platform
parallel with carina and separated fromit by a trough. Trough shallow in posterior half and deepest at anterior part.
At posterior end, node of inner platform fused with carina. Rather highbut narrow transverse nodes developedon inner platform. Outer side of cup
slightly wider and shorter than innerside and subovate in outline. Marginof outer platform with fused nodes
which are most prominent near midpoint to anterior end. Blade long,almost equal length with cup and bears
serrate denticles. Lower side of cup
strongly excavated.
Lower side ofblade grooved.
Remarks :-This unidentified species
seems to be a new species or new subspecies. Gnathodus cfr. roundyi GUNNEL
described by KOIKE (1967, PI. 1, fig. 27,
non fig. 28) is similar to the specimens.
It slightly resembles Gnathodus girtyi
intermedius GLOBENSKY, but the present
one differs from his subspecies in isolated nodes of the carina, fused nodesof the outer and inner platform at theposterior end of the cup of the latter.
Also the outer cup of the present species is lower than the inner. Gnathodus
bilineatus bollandensis HIGGINS and BouCKAERT is also allied one. Not so laterally expanded outer platform, weakertransverse ridge of the inner platform
and fused nodes on the posterior partof the cup of G. bilineatus bollandensis
differ from the present one. This form
also resembles Gnathodus roundyi described by several American authors andnow identified as Neognathodus bothrops
MERRILL (1972), bl!t the present material
bears fused and continuous nodes of thecarina and poorly developed ornamentation of the outer platform.
Occurrence :-Rare in various levels of

Unit almost symmetrical and slightly
arched, elongate lanceolate in outline
and tapering anteriorly. Carina composed of 7 or 6 discrete denticles. Denticles node-like and laterally not compressed, erect or slightly directed posteriorly. Upper surface of platformsmooth and lacking any ornamentation.
Lateral furrow along carina shallow.
Cusp and denticles of anterior end
larger than other dentic1es. Pit locatedat posterior end, broadly flared andcomparatively large, surrounded byflange.
Basal groove well-developed
but shallow. Aboral keel slightly elevated and wide.
Remarks :-This species is similar to
Gondolella n. sp. A described by MERRILL
and KING (1971) from the lowest Pennsylvanian of Illinois, certain specimens
of Gondolella bella STAUFFER and PLUMMER described by KOIKE (1967) from theAtetsu Limestone, Japan. This new
species differs from these species indiscreate node-like denticles and slightly
elevated aboral keel. Gondolella gymna
MERRILL and KING and Gondolella (?)
sp. A (KOIKE, 1967) are also similar
species to this new species. Gondolella

The occurrence of a Jurassic ammonite
from a small valley near Inuyama, northof Nagoya, is rather well known among
those who are interested in the JapaneseJurassic. The first report of this ammonite was that of FUJII and MIYAKAWA
in 1953, unfortunately in the form of amimeograph. In the same year, MATSUMOTO noted its occurrence briefly (1953,
p. 358) in published form. The discovery
was also briefly mentioned by SATO
(1962, p. 8-9) based on an onH communication from Prof. MATSUZAWA, and reported in more detail by MIZUT ANI (1964,
p. 42).
Recently, Jurassic ammonites havebeen reported from beds previously
believed to have been Paleozoic at twoother localities in the Yamaguchi Terrain
of Inner** Japan. One locality is near
Mashiko, east of Utsunomiya (SUZUKI
and SATO, 1972) in finely laminated blacksilty shale, the age of which has notdefinitely been determined. The otherlocality is at Higuchidani in Muikamachi,
Shimane Prefecture (IMAMURA, NUREKI
and OKIMURA, 1966) ; here the ammonites
are collected from the river float andthe beds of origin have not been established.
These two localities and the one near
Inuyama are all in the Yamaguchi
Terrain (KOBAYASHI, 1941), which had
supposedly been folded and partly metamorphosed before Upper Triassic or,
locally, Lower Jurassic. Recent stratigraphic work on this terrain is clarifying the wide development of MiddleUpper Traissic strata, dated by conodont faunas found in the chert andlimestone beds (e. g., IGo, 1972).
The newly dated Jurassic beds seemto have been folded together with the
Paleozoic and Triassic strata, exceptthat there remains some uncertainty
about Higuchidani beds; therefore amore precise dating of these beds has
been eagerly awaited.
The ammonite specimen discovered atInuyama was deposited in Nagoya
University (Institute of Earth Sciences);in order that it might be describe4 forpu blic refererice,

Tadashi SATO

(University of Tokyo), Prof. Em. I.
MATSUZAWA (Nagoya University), andProf. T. KIMURA (University of Tokyo,
formerly of Nagoya University) arranged
for study of the specimen. Prof. MIZUTANI (Nagoya University) kindly sentme the specimen along with valuable
information about the geology of thearea. At my request, Mr. N. KONDO of
Nagoya University guided me to thefossil locality and neighboring areas. I
am very grateful to all who extended
me the courtesies necessary to study
the ammonite and its locality.
The specimen is said to have been
discovered at a small cliff facing a creek
confluent with the valley of the Kiso
River, about 500 m NE of Kurusu, Inu-

yama City (Fig. 1). It was found in 1951
by Mr. O. SENGOKU, then a school boy,
who happened to be playing there. Mr.
T. SENGOKU, his father, brought it to
the Institute of Earth Sciences of Nagoya
University where it is now deposited andregistered as specimen No. ESN 7000l.
Since then, efforts to clarify the geology of the area and especially .toestablish the fossil bearing horizon havebeen made repeatedly by many workers,
including Prof. KIMURA and Prof. MIZUT ANI; yet the fossil bearing horizon has
never been firmly established because of
the poor exposure.
The small cliff is situated about 100 mfrom the junction of the creek with the
Kiso River. The fossil is an internal

mold of an ammonite of moderate size,
impressed on the surface of black finely
laminated siltstone. Although the horizon
from which the specimen originatedcould not be positively determined, thedebris scattered around the assumed
point of discovery is similar lithologi·
cally to the specimen. At any rate thespecimen in question seems surely tohave been derived from the catchment
area of the creek.

guchi Terrain of central Japan. It isvery likely that the sea spread overmost of the terrain in this epoch, as
judged from the occurrence of Upper
Jurassic ammonites (though the ages of
the ammonites differ slightly), except in
the northern part which appears tohave undergone uplift indicated byevidence in the Kuruma and Tetori
intra montane basins. It remains uncertain, however, if the sea extended
farther south onto the Sambagawa
metamorphic belt.
The "Eo-Nippon
Cordillera" (KOBAYASHI, 1941), which if
present at all, divided the Upper Jurassic seas into the Japan Sea and Pacific,
should be restricted therefore to a muchnarrower belt than those postulated by
KOBAYASHI and others.

The Age of the Beds
As will be described the ammonite isa form probably belonging to Choffatia(Subgrossouvria) of the Pseudoperisphin·ctinae. The specimen is incomplete andthe species could not be accurately
determined. The generic and subgenericassignment ensures that the beds are
Upper Bathonian to Lowest Oxfordian.
Even if the generic and subgeneric assignments are not accepted, however, aMiddle to Upper Jurassic age for thebeds would be warranted by the inclusionof the specimen in the Family Perisphinctidae. Subgrossouvria is a subgenus
widely distributed in the Mediterranean
region in addition to East Africa, Iran,
Cutch (India), and Mexico; its occurrencein Japan therefore is not surprising.

Description:-Coiling is evolute, overlapping of the inner whorls very slight;
section of the whorl is hard to ascertain
because of compression, but the flanks
are judged to have been gently inflatedwith the maximum thickness at thelower part; ventral region is not preserved; umbilical is wall very inclined
and rounded.
Ribbing on the inner whorls is rectiradiate and dense; probably bifurcating
regularly; this ribbing suddenly changes
after a shallow but rather oblique constriction into plicate primary ribs which
are much less numerous, more distantly
spaced, and highest in relief at theumbilical border. The furcation of the
se-conda'ry ribs from the - primaries israther obscure, but it is likely that bi:
or tri-furcations occur at rather indis
tinct points of branching.
There are three rather shallow andobscure constrictions per whorl.
The suture-lines are not observable.
Affinities and Compal'isons: - The
sudden modification of the ribbing 'while
the shell is still small is characteristicof this form. The number of primaryribs suddenly decreases ·from about 60
to 40 after a wide shallow constriction.
Although the larger whorls are notpreserved, this modification reveals thatthe living chamber of the senile stage
would not be much larger ; therefore
the present specimen mig ht represent
the microconch.
Sudden modification of ribbing is observable in Subgl'ossouvl'ia as well as inmacroconchs of the Perisphinctinae; e.g.
Pel'isphinctes s. s., Lio sphinctes, etc.
However, such modification occurs in
Perisphinctid macroconchs at muchlarger diameters , for instance, at a 200250 mm diameter in Pel'isphinctes s. s.,

640. A Jurassic Ammonite from near Inuyama
and at a 120-150 mm diameter in LioThese genera attain a gigantic size, and modified ribs are moreor less cuneiform.
As admitted recently by a number ofauthors, microconch dimorphs of thesegigantic forms do not show distinct
modifications of ribs. Therefore, thepresent specimen does not belong to anyof the genera cited above.
5ubgrossouvria, treated as a subgenus
of Choffatia by MANGOLD (1970, p. 157),shows also a rather abrupt modificationof ribs. Among various species of thissubgenus, C. (5.) recuperoi (GEMMELLARO)
is superficially very similar to the present
form as judged by the figures of GEMMELLARO (reproduced by ARKELL, 1958,
p. 221, fig. 80/1a, b). The number offine, undivided ribs visible within theumbilicus is as high as 56 when the shell
is about 50 mm in diameter, and decreases
rather abruptly to about 30. However,in the ribs on the outermost preserved
whorl of the holotype (probably one
more volution overlaps the original
specimen, judging by the presence ofthe scar of the umbilical seam on thelast preserved whorl) the branching of
secondary ribs occurs lower on the flanks
than in the present form.
Because important criteria such aswhorl section, ventral aspect and suturelines are unknown, it is reasonable not
to give a definite specific name to thepresent form.
Occurrence :-From a small creek about
500m NE of Kurusu, Inuyama City. The
horizon from which the specimen wasderived could be a black laminatedsiltstone bed.

Introduction and Acknowledgements
During the study of Upper Triassic
ammonoids, ISHIBASHI collected someconodonts from the limestone of the
Nakijin Formation (ISHIBASHI, 1969) inOkinawa-lima. The conodont-bearing
limestone was obtained from the Juvavites cf. kellyi Zone (ISHIBASHI, 1970)
which is characterized by the occurrences of arcestids and juvavitids.
ISHIBASHI correlated this zone with theupper Carnic Tropites welleri Zone(TOZER, 1967) of North America. The
conodont fauna also contains important
species for age determination andRemarks on the Conodont Assemblage

of the horizon 3 (AKa), the upper partof the Nakijin Formation. ISHIBASHI(1973) reported some ammonoids fromthis horizon such as Jovites? sp., Anatomites d. taulai (Mo]s), Tardoceras? sp.
and Arcestes (Stenarcestes) sp. A. Fromthe horizon 1 (Ya) about 20 m above
this horizon following ammonoids werealso identified by him, Hannoceras (H.)
henseli (OPPEL), Jovites d. dacus (Mo]s),
Juvavites d. kellyi SMITH, Discotropites
quinquepunctatus (Mo]s), D. d. plinii(Mo]s). Hoplotropites ct arionis (Mo]s),H. georgii (Mo]s), Arnioceltites d. arietiti/ormis (Mo]s), Arietoceltites arietitoides(DIENER), Arcestes sp., Hypocladiscites
subaratus (Mo]s) and others. He referred these two. horizons to the Juvavites d. kellyi Zone and correlated thiszone with the Tropites welleri Zone ofNorth America.
.
The conodont fauna comprises Epigondolella nodosa (HAYASHI),· Neohindeodeila triassica (MULLER), Enatiognatus
ziegleri(DIEBEL), and Cypridodella d.
conjiexa MOSHER.' Epigondolella nodosais most abundant and comprises about 35
specimens but the others are represented
by only one or two specimens in approximately 2 kg rock sample. Among theseconodonts E. nodosa is a quite important
indicator for age. This species was
first reported by HAYASHI (1968) fromlimestone conglomerate of the basal
part of the Adoyama Formation in
Kuzuu, southern Ashio Mountains. HAYASHI assigned the fauna including thisspecies as Permian in age .. According
to the study by KOIKE, the conodont
fauna is composed of derived fossils.
This species is associated not only with
Epigondolella abneptis (HUCKRIEDE) andE. postera (KOZUR and MOSTLER) whichindicate late Carnian to middle Norian
but also with Middle Permian spathognathodids and gnathodids, and Scythian to Carnian neospathodids andgondolellids. Detailed correlation between conodont assemblages and ammonoid zones of Europe and North America
was carried out by MOSHER (1968,1970), SWEET et al. (1971),' KOZUR and641.

Upper Triassic Conodonts from Okinawa-Jima

MOSTLER (1971, 1972), KOZUR (1972) and
KRYSTYN (1973). In British Columbia
this species guides to the uppermost
Carnian Klamathites macrolobatus Zone
and the lowermost Norian Mojsisovicsites kerri Zone.. In Hallstiitter Kalk ofAustria this species also occurs fromthe Anatropites Bereich of the uppermost Carnian Tuval Stage and from the
Mojsisovicsites kerri Zone of the lowermost Norian Lac Stage. On the basisof the study of conodont assemblage,
KRYSTYN (1973) correlated the Anatropites Bereich of Europe to the Klamathites macrolobatus Zone of North
America. The conodont assemblage
treated herein contains no Epigondolella
abneptis HUCKRIEDE which appears inupper part of Tuval Stage and later
than Epigondolella nodosa. Accordingly,
this fauna may indicate the lower partof the Anatropites Bereich of Europe or
the Klamathites macrolobatus Zone ofNorth America. The age is almost
equivalent -with the conclusion by ammonoid assemblage.

Description;- This species is characterized by anteriorly high carina andelongated platform with nodes on anterior lateral margins. On immature
specimens platform expanded laterally
at central portion and abruptly tapered
anteriorly. Posterior end rounded andscooplike. Lateral margins upturned
at central portion and crenulated at
growth stage. Keel relatively narrowand high. Groove ends in flaring cavity.
On mature specimens platform almost
equivalent in width at posterior tocentral portion and gradually tapered
anteriorly. Crenulation or nodes onlateral margins developed in anterior
two thirds of platform. Keel low andbroad, bearing longitudinal striation andending in small pit. On large specimens
keel probably bifurcated.
Remarks;- Immature specimens of
this species are closely similar to thoseof Paragonodolella polygnathiformis (BuDUROV and STEF ANOV) in gereral aspect.
However, the lateral margins of platform of this species are thin and morestrongly upturned. Mature specimensof this species are rather similar to
Epigondolella abneptis (HUCKRIEDE). This
species, however, posesses more elongated platform and no nodes on posterior margin.

in the size of C. nodulifer. BELAYEV A(1971) added credence to KOLBE'S postulate by making actual field observations in the Equatorial Pacific. Subse·
quently, BELAYEVA (1972) has reported
additional species whose size is apparently dictated by upwelling.
The purpose of this note is to add to
our knowledge of single species whichshows considerable size variation relative to geographic location (in this study
Annellus californicus) and to offer some
speculation concerning the cause of thisparticular phenomenon. Our samples
were obtained from Miocene deep· sea
sediments of the eastern Equatorial
Pacific and from Miocene sediments on
the Noto Peninsula, western Honshu
Island, Japan (see Fig. 1 for locationsof samples used).

Introductory Note
The fact that individual Diatom
species vary considerably in size haslong been established in the literature.
Their mode of reproduction allows forsize variations in single species ranging
from less than 10 p to over 100 p. In
addition to this, size variations may be
a response to changing or differing
ecological conditions.
W HIM PEN NY(1936), for example, found size changes
in Rhizosolenia spp. as the season progressed. KOLBE (1954) postulated thatchanges in the rate of upwelling ofdeep water may be related to changes* Received July 15, 1974; read Oct. 19, 1974

from the equatorial Pacific came from sites 77 and 78 of DSDP Leg IX. The samples
on Noto Peninsula came from the Hojuji and Iida Formations.

The Diatom species Annellus cali/ornicus TEMPERE has received considerable
attention in the literature as a stratigraphic marker (HANNA, 1932 ; REINHOLD,
1937; WbRNARDT, 1967; NAKASEKO etaI., 1972; BURCKLE, in press, to mention
only a few). OPDYKE et aI. (1973) and
BURCKLE (in press) have pointed· outthat this species is a rather· reliable
marker for the Early/Middle Miocene
boundary-its first appearance occurring just before the beginning of the
Middle Miocene.
In addition, this species has received
considerable attention because of its
peculiar morphology. HANNA (1932)
was one of the first to point out thatthe species was like a hoIIowcylinder,
open at both ends. This observation
was challenged by RYDE (1962) whose
careful work showed the existence ofa sieve plate in the central region.
Accordingly, RYDE transferred this form
to the genus Craspedodiscus. With theaid of the Scanning Electron Microscope, WORNARDT (1970)iIIustrated thiscentral sieve plate but showed that it

originated as an invagination of theinner wall. Hence the taxonomic position of this form is still somewhat in
doubt and, for this reason, we retain
the name Annellus cali/ornicus.

Methodology
Samples were prepared after the
method described by SCHRADER (inpress) .. Approximately 1 gram of sample
was placed in a 1: 1 solution of acetic
acid and hydrogen peroxide. The residue was centrifuged seven times and. further concentrated by differential
settling in beakers of 10 cm height.
Disposable pipettes were used to transfer the Diatoms in suspension to apermanent slide.
Each slide was scanned for Annellus
cali/ornicus. Specimens were spottedwith mechanical stage coordinates andwhere possible, two measurements oneach specimen were made-length andwidth (see Fig. 2 for definition of theseparameters).

The Data
Fifty-five specimens were measured
from the Equatorial Pacific and 69
specimens from the Japanese Noto Peninsula section (Hojuji and Iida Formations). Widths for the Equatorial Pacificspecimens ranged from 14.2 to 92.9 flwith a mean of 54 fl. Lengths range from10 to 43.1 fl and · a veraged 33.4 fl. The
standard deviation on width and length
measurements were 13.6 and 4.7, respec tively. The Japanese specimens had

The valu es we obtained indicate thatthe differences between the two sample
sets are significant at the 99% level.
Such values permit us to concluded
that the differences are real.
Discussion
It is interesting to specu late on those
influences, ecological or otherwise, that
may operate to produce such size differences. WHIMPENNY (1936) invokedseasonality as a cause.
KOLBE (1954)
invoked changes in the rate of upwelling (and, thus, changes in nutrient concentration) as a causative factor.
From a consideration of the geographic distribution of our samples themost obvious cause may be temperature.
Many organisms do increase in siz~from the equator toward the poles. A
second suggestion is that the size dif-.
ferences may be due to different habi-:

tats. The Equatorial Pacific specimens
lived in an open ocean environment,
quite distant from land. The Japanese
specimens were enclosed in sediments
representing a near shore (shelf) environment. Coastal environments normally have much greater concentrationsof dissolved nutrients. This factor may
contribute to the larger size of theJapanese specimens.
Still, a third possibility is that selective solution has destroyed the larger
forms of A. cali/ornicus in the Equatorial Pacific-leaving only the smaller
forms behind as a residue. Of these
possibilities, we prefer to speculate on
the first two. It seems unreasonable
to invoke dissolution as a factor.
Such a conclusion implies that theJapanese samples represent a more
complete population. If this is so thenthe lower limit and widths and lengths
for the Japanese samples (43.3 and 34.1
p., respectively) should be close to thosefor the Equatorial Pacific samples (14.2
and 10 p., respectively). The fact thatthey are not suggests that dissolution
is not a major factor in the differences
between these two populations.
This leads us to conclude that one orboth of the first two factors may haveoperated to cause the size differences.
It seems reasonable to conclude further
that changes in size with time may
cast some light upon temporal changes
in the environments of deposition.
