OLIGOCENE FORAMINIFERA NEAR MILLRY, ALABAMA

By JOSEPH A. CUSHMAN and WINNIE MCGLAMERY

ABSTRACT

This paper records an Oligocene foraminiferal fauna from the 

Chickasawhay marl at a locality near Millry, Ala. Approximately 42 genera are present, including 71 species and varieties. 

Ten species are identified only as to genus. The fauna is similar 

to that found at Choctaw Bluff, Ala.

INTRODUCTION

Collections, especially for Foraminifera, were made 

in the spring of 1937 from a limestone exposure 1.4 

miles north of Millry, Washington County, Ala. 

These collections have been studied, and the results 

are presented here with illustrations of many of the 

species found.

The locality is in a road cut of State Highway No. 29, 

in sec. 17,T.8N.,R.3 W., where the following sequence 

is displayed:

In 1926 the exposure was referred by Cooke 1 with 

doubt to the Byram marl. Howe and Alexander 2 in 

1934 placed it in the lower Chickasawhay member of 

the Catahoula sandstone. In a later paper (1935), 

Cooke 3 refers this limestone to the Chickasawhay marl 

member of the Byram. The Chickasawhay marl is 

now classified as an independent formation.

from the locality are specimens of Ostrea mcksburgersis 

Conrad, taken from a railroad cut of the Tennessee & 

Northern Railway, which parallels the highway. The 

limestone is extremely fossiliferous, especially in the 

lower portion, but the state of preservation is too poor 

for identification of most of the macrofossils.

The foraminiferal fauna contains numerous species 

already recorded from the Choctaw Bluff local: ty 

previously described by us.4 A number of new spec; es 

from the present locality have been described el^ewhere 5 so that they might be available to workers 

pending the publication of this paper.

Several species are not well enough preserved to g: ve 

full specific characters. These are referred to under 

their generic names and figured for future reference, 

as more work in this area may result in the finding of 

complete and more abundant specimens.

Most of the species are identical with or closely 

related to those known from the Oligocene Byram mr.rl, 

and it is probable that these beds are of Oligocene age. 

As is usual, the softer clays yield a much richer fauna 

than the limestone, probably owing to the mechanical 

difficulties of breaking down and washing the harder 

material of the limestone.

Veiy rare and rather poor specimens from bed 3 

seem to belong to this variety, which is known from the 

Oligocene of Mississippi, Alabama, and Cuba and from 

the upper Eocene of Georgia, Alabama, South Carolina, 

Mississippi, and Texas.

Family VALVULINIDAE

Genus CLAVULINA D'Orbigny, 1826

Clavulina cf. C. tricarinata D'Orbigny

In our previous paper on the Oligocene Foraminifera 

from Choctaw Bluff (U. S. Geol. Survey Prof. Paper 

189-D, p. 104, pi. 24, fig. 3, 1938) a number of specimens 

were recorded and figured from the Oligocene. Very 

similar specimens, although less well preserved, occur in 

our present material, thus confirming the existence of 

this genus in the Oligocene of the Gulf Coastal Plain. 

The fragments occur in beds 2, 4, and 6, showing that 

they were persistent during the deposition although 

represented by a single fragmentary specimen in each 

bed.

Family MILIOLIDAE

Genus QUINQUELOCULINA D'Orbigny, 1826 

Quinqueloculina tessellata Cushman

Plate 4, figure 1

Quinqueloculina tessellata Cushman, U. S. Geol. Survey Prof.

Paper 129-F, p. 142, pi. 33, fig. 8; pi. 34, fig. 1, 1922. 

Cushman, U. S. Geol. Survey Prof. Paper 133, p. 54, 1923.

This species is known from the Oligocene Byram marl 

and Glendon limestone of Mississippi. Specimens are 

rare in bed 2 but are characteristic, as the figure will 

show.

Quinqueloculina sp.

Plate 4, figure 2

A few specimens similar to the one figured have evidences of longitudinal costae, but not enough are 

available to make it possible to give a definite specific 

determination or to be sure that these are really adult 

specimens.

A few poorly preserved specimens may be smooth 

forms, but they have not been included nor figured, 

though they indicate that other species are present.

Genus MASSILINA Schlumberger, 1893 

Massilina decorata Cushman

Howe and Wallace, Louisiana Dept. Cons. Geol. Bull. 2, 

p. 20, pi. 2, fig. 6, 1932.

This species is very rare in this material, occurring 

only in bed 5. The species is known from the lower 

formations of the Oligocene of Alabama and Mississippi 

and also from the uppermost Eocene of Mississippi.

Genus SPIROLOCULINA D'Orbigny, 1826 

Spiroloculina byramensis Cushman

Spiroloculina byramensis Cushman, U. S. Geol: Survey Prof. 

Paper 129-E, p. 101, pi. 25, figs. 4a, b, 1922.

A single broken specimen from bed 5 is the only 

representative of this species in our material but is very 

typical in its surface characters, with an ornamentation 

consisting of fine hexagonal depressed areas with raised 

edges. The species is apparently recorded only from 

the Byram marl of Mississippi.

Genus PYRGO Defrance, 1824 

Pyrgo oligocenica Cushman

Plate 4, figure 4

Pyrgo oligocenica Cushman, Cushman Lab. Foram. Research 

Contr., vol. 11, p. 26, pi. 4, figs. 5a, b, 1935.

A few specimens of this species were found in bed 5, 

one of which is figured. The only other record seems 

to be from the type locality in the Byram marl near 

Waltersville, Miss. Our specimens are slightly worn 

and do not show the costae as heavily developed as in 

the type specimen, with which they have been compared, but they are evidently identical with it.

Family OPHTHALMIDHDAE

Genus VERTEBRALINA D'Orbigny, 1826

Vertebralina advena Cushman

Cushman and Hanzawa, Cushman Lab. Foram. Research 

Contr., vol. 13, p. 44, 1937.

This species is represented in our material by the 

single specimen figured from bed 5. Other records are 

from the Oligocene of the Coastal Plain of Mississippi, 

all from the Byram marl, except that of Howe from 

the Ked Bluff Clay.
OLIGOCENE FORAMINIFERA NEAR MILLRY, ALABAMA 67

Family LAGENIDAE

Genus MARGINULINA D'Orbigny, 1826

Marginulina sp.

Plate 4, figures 6, 7

Three specimens only of a species, which is here 

figured, were found, but these are not enough to make 

it possible to apply a definite name. More should be 

available before it is described in full. They are from 

bed 5 of our section.

Genus DENTALINA D'Orbigny, 1826 

Dentalina pseudoinvolvens Cushman and McGlamery

Plate 4, figures 8, 9

Dentalina pseudoinvolvens Cushman and McGlamery, Cushman 

Lab. Foram. Research Contr., vol. 15, p. 45, pi. 9, figs. 

1, 2, 1939.

Test elongate, slender, slightly arcuate, very gently 

tapering, with the greatest diameter at the last-formed 

chamber, initial end with a short spine; chambers few, 

about six in the adult, inflated, somewhat pyriform, 

proloculum fusiform, later chambers increasing very 

gradually in size as added, more inflated on one side; 

sutures distinct, depressed, strongly limbate; wall 

ornamented with distinct, low, longitudinal costae, 

sometimes tending to become slightly spiral; aperture 

radiate, at the end of a slightly prolonged, tapering 

neck. Length, as much as 1.25 millimeters; diameter, 

0.15 to 0.18 millimeter.

The types are from bed 5, but the species also occurs 

in bed 3.

This species differs from the Cretaceous species D. 

irwolvens Cushman in the more separated and inflated 

chambers, deeper and more limbate sutures, and less 

prominent costae. It is veiy similar to a foim figured 

from the Miocene of Florida as Dentalina sp. (Florida 

Geol. Survey Bull. 9, pi. 9, figs. 3, 4, 1932).

Dentalina cf. D. communis D'Orbigny

Plate 4, figure 10

A very few specimens from bed 5, one of which is 

figured, have a smooth surface. The chambers are 

somewhat irregular but in general increase rather uniformly in size as added. The aperture is at the outer 

angle of the last-formed chamber and is radiate.

Dentalina sp.

Plate 4, figures 11, 12

A few specimens of a peculiar form from bed 5 may 

belong to Dentalina,, although the apertural characters 

are missing, as all the specimens are broken at the end. 

The wall is smooth and the chambers are irregular in 

size.

Genus NODOSARIA Lamarck, 1812 

Nodosaria cf. N. catesbyi D'Orbigny

Plate 4, figures 13-19

In our paper on the Choetaw Bluff section, specimens 

very similar to those figured here were referred to 

D'Orbigny's species.6 The present material occurs in 

beds 3, 4, 5, and 6. The specimens show a considerable 

amount of variation and may be distinct from the 

Recent West Indian species. Two-chambered and 

three-chambered specimens are the rule, in which 

character they are like the Recent species, but our 

material includes four-chambered and even five-chambered specimens. It is possible that this may be a 

distinctive species of our Oligocene.

A few specimens seem to have a slightly flattened and 

irregular early part suggestive of Vaginulina. The 

later chambers in the two forms are very similar in 

shape, size, and ornamentation.

Nodosaria vertebralis (Batsch) ?

Plate 4, figure 20

The single specimen figured is from bed 3 of our 

section. It has more chambers, a thicker wall, and 

much stronger costae than the preceding species. 

More specimens are needed to make it possible to 

determine the species with certainty.

Genus VAGINULINA D'Orbigny, 1826 

Vaginulina sp.

Plate 4, figure 21

The single specimen here figured is from bed 3. It 

is a much flattened form with a strong keel on the 

dorsal border and with the ventral border truncate, 

suggesting some of the species referred to Planularia.

Genus LAGENA Walker and Jacob, 1798 

Lagena cf. L. lineata Williamson

Plate 4, figure 22

A very few specimens from beds 5 and 6 are rounded, 

usually with a slight spine at the base and with the 

surface covered by slightly irregular longitudinal costae. 

As is generally true of L. lineata, the shape is somewhat 

irregular, especially at the basal end, which may be 

asymmetrical.

Lagena striata (D'Orbigny) var. substriata Williamson

Plate 4, figure 23

A very few specimens with fine costae seem to belong 

under this variety. They are from beds 1 and 5. T^ie 

body of the test is slightly pyriform, and there is a very 

definite, somewhat elongate neck, slightly tapering to 

the apertural end.

68 SHORTER CONTRIBUTIONS TO GENERAL GEOLOGY, 1941

Lagena cf. L. slriato-punctata Parker and Jones

Plate 4, figure 24

The single specimen figured is from bed 3 and is the 

only one of the kind so far noted in our material. It 

resembles L. striato-punctata in the peculiar ornamentation of the surface, which consists of longitudinal costae 

characterized by punctae or tubular structures at 

regular intervals that give an unique appearance to the 

costae. In our specimen the short cylindrical neck has 

spiral costae.

Lagena sulcata (Walker and Jacob)

Plate 4, figure 25

A very few specimens from bed 5 are similar to that 

figured here, in which the test is broadly pyriform, 

broadest below the middle, thence gradually tapering 

to the acute apertural end. The surface has a comparatively few well-developed acute costae running 

from base to apex. At the apertural end in our specimens there is a slight enlargement just below the 

aperture.

Family POLYMORPHINIDAE

Genus GUTTULINA D'Orbigny, 1839 

Guttulina cf. G. lehneri Cushman and Ozawa

Plate 4, figures 26, 27

Rare specimens may be questionably referred to G. 

lehneri, which has already been recorded from the 

Oligocene of Choctaw Bluff.7 They occur in beds 1, 3, 

5, and 6 and show considerable variation.

Guttulina cf. G. problema D'Orbigny

Plate 4, figures 28-31

This species has also been recorded from the Oligocene 

of Choctaw Bluff. Some of the specimens seem to tend 

toward G, lehneri, but the two can usually be easily 

distinguished. They occur with G. lehneri in beds 1, 

3, and 5.

Genus GLOBUIINA D'Orbigny, 1826

Globulina gibba D'Orbigny

Plate 4, figure 32

This widely distributed and variable species occurs 

in considerable numbers in all six beds of the section. 

It was found also at Choctaw Bluff.

from the upper Eocene to the Miocene of the Gulf 

Coastal Plain. It occurs in bed 6.

fig. 2, 1932.

Specimens from beds 1, 3, and 4 are very similar 

indeed to Recent specimens of this variety. It has 

previously been recorded as a fossil from the Pleistocene, Pliocene, and Miocene of the Gulf Coastal Plain, 

although specimens from the earlier Tertiary of Europe 

have been referred to it. Living specimens are often 

found attached to other objects, and one of our specimens is attached in a similar way to a shell fragment.

Test slightly longer than broad, both ends broadly 

rounded, periphery broadly rounded, thickness slightly 

less than the breadth; chambers few, only slightly 

inflated, increasing rapidly in size as added, lastformed chamber making up at least half the surface in 

the adult; sutures distinct, sigmoid in the adult, little 

if at all depressed, very slightly Umbate; wall ornamented with numerous short spines, rather evenly scattered 

over the whole surface; aperture terminal, radiate. 

Length, 0.60 to 1.25 millimeters; breadth, 0.40 to 

1.00 millimeter; thickness, 0.35 to 0.85 millimeter.

The holotype is from bed 3, but the specie1* occurs 

also in bed 5.

This species differs from Globulina, gibba D'Orbigny 

var. tuberculata D'Orbigny in the much more distinctive 

spines and more elongate test, which is also slightly 

compressed.

OLIGOCENE FORAMINIFERA NEAR MILLRY, ALABAMA 69

This species occurs in some numbers in beds 3 and 5. 

The transverse outline is squarely truncate and often 

slightly keeled. In some specimens very fine longitudinal costae are weakly developed. No specimens were 

found that could be referred to the closely allied P. 

advena Cushman, which was found at Choctaw Bluff.

section. It is a widely distributed species in the Oligocene of the Gulf Coastal Plain and occurs at many 

localities in the upper Eocene of the same area.

Test planispiral, involute, periphery rounded, lobulate, umbilical area somewhat depressed but with a 

central boss; chambers very distinct, 8 to 10 in the 

adult whorl, slightly inflated, increasing rather evenly 

in size as added; sutures very distinct, deeply excavated, 

limbate, very slightly curved in the earlier stages, 

nearly straight and radial in the last-formed portion; 

wall mostly smooth, finely perforate, the inner portion 

of the sutures toward the umbilical region, and the 

central boss ornamented with fine granular projections; 

aperture, low, elongate, at the base of the last-formed 

chamber. Length, 0.40 to 0.45 millimeter; breadth, 0.30 

to 0.40 millimeter; thickness, 0.20 millimeter.

The holotype is from bed 5 of the section.

This species differs from N. advenum Cushman in the 

more lobulate and more rounded periphery, less deeply 

excavated sutures, and fewer chambers.

The holotype has two supplementary chambers near 

the periphery between the last two chambers of the 

main coil, but this is entirely an accidental feature.

Foram. Research Contr., vol. 15, p. 47, pi. 9, figs. 5a-c,

1939.

Test slightly longer than broad, slightly evolute, 

periphery broadly rounded, slightly lobulate in the last 

portion, ventral side slightly umbilicate, dorsal side 

slightly umbonate; chambers distinct, about ten in 

the adult whorl, somewhat inflated, more so in the lp,stformed portion of the adult whorl, increasing gradually 

and rather evenly in size as added; sutures distinct, 

earlier ones strongly limbate, curved, not depressed, 

later ones very slightly curved, depressed; wall smooth 

and polished, very finely perforate; aperture a low 

opening at the base of the last-formed chamber, just 

ventral to the periphery, sometimes with a slight, overhanging Up. Length, 0.40-0.50 millimeter; breadth, 

0.35-0.40 millimeter; thickness, 0.20 millimeter.

This species is common in our section and occurs in 

beds 1, 4, 5, and 6. The holotype is from bed 1.

This species differs from Nonionella danvillensis 

Howe and Wallace in the less prominent umbo on the 

dorsal side, lack of the elongate projection on the 

ventral side, and thinner test.

Genus ELPHIDIUM Mont fort, 1808 

Elphidium sp.

A very few poorly preserved specimens evidently 

belong to this genus but do not warrant specific 

determination.

Nodogenerina? sp.

Plate 5, figure 13

A single specimen from bed 4 is difficult to place. 

It is uniserial, distinctly and coarsely perforate, with a 

terminal aperture. There is no true phialine lip, 

although there is a very slight thickening about the 

elongated aperture. The early chambers are rounded 

in section, but later ones become progressively more 

compressed.

Family BULIMINIDAE

Genus BULIMINELLA Cushman, 1911

Buliminella cf. B. elegantissima (D'Orbigny) var.

Numerous specimens of a form like that figured show 

the coils extending down and covering the initial end. 

Such specimens occur in beds 1, 3, 5, and 6. They are

evidently related to the more definitely spiral form that 

is more like the Recent species and that occurs at 

Choctaw Bluff. This variety may be found to be 

characteristic of this part of the Oligocene.

This is evidently a characteristic species of the Oligocene. The type locality is Waltersville (VicksburgX 

Miss., and it is a fairly common species at Choctaw 

Bluff. It occurs in some numbers in beds 3 and 5.

Entosolenia laevigata (Reuss) 

Plate 5, figures 19-21

This species has already been recorded from Choctaw

in the series, but the characters as shown in our figure 

are closely held.

Test elongate, somewhat compressed, about three 

times as long as broad, sides for the most part nearly 

parallel or decreasing in breadth toward the apertural 

end, which is somewhat truncate, initial end triserial, 

bluntly pointed, periphery rounded; chambers numerous, very distinct, about three pairs of biserial ones in 

the adult, slightly inflated; sutures distinct, curved, 

slightly depressed; wall thin and nearly transparent, 

very finely perforate, smooth and polished; r,perture 

rather large, comma-shaped, oblique, with a slight lip. 

Length, 0.45 to 0.50 millimeter; breadth, 0.12 to 0.15 

millimeter; thickness, 0.10 millimeter.

The holotype is from bed 5 of the section. It occurs 

also in bed 6.

This species differs from Virgulina bramlettei Galloway 

and Morrey in the shorter chambers, less coarsely perforate wall, and larger aperture. The form from 

Choctaw Bluff,9 and also that from the Meson (Oligocene) of Mexico, 10 referred to V. bramlettei are probably V. alabamensis.

from Choctaw Bluff and seem definitely to place this 

species as a characteristic form of the Oligocene of 

Alabama. The specimens vary considerably, both in 

general shape and amount of twisting.

described from the typical Byram marl at Byram, 

Miss. It occurs in the Chickasawhay marl at Choctaw 

Bluff in considerable numbers. In the present material 

it is found in typical form in beds 1, 3, and 5. The f,dult 

character of having the last-formed chamber very thin 

on one side and caving in is a peculiar feature unlike 

that of any other species. From the present records it 

seems to be a characteristic Oligocene species of this 

region.

Valvulineria paucilocula Cushman, Cushman Lab. Foram. Research Contr., vol. 11, p. 37, pi. 5, figs. 7 a-c, 1935.

Test rounded, somewhat compressed, periphery 

broadly rounded, dorsal side slightly convex, ventral 

side slightly concave in the center; chambers distinct, 

five in the adult whorl, of rather uniform shape, increasing regularly in size as added, the last-formed 

chamber making up on the ventral side nearly one-half 

the surface; sutures distinct, slightly depressed, gently 

curved; wall thin, coarsely and distinctly perforate 

except in a clear area above the aperture on the ventral 

side; aperture an elongate, arched opening on the ventral side, with a flattened, somewhat angular projecting 

lip above it. Length 0.35 to 0.40 millimeter; breadth, 

0.30 millimeter; thickness, 0.20 millimeter.

The types of this species are from the Oligocene 

Byram marl, 8 feet above ledge at water's edge, under 

suspension bridge on Pearl River, Byram, Miss. It is 

fairly common in our material from beds 1, 4, 5, and 6 

of the section. As it has not previously been recorded 

since the first reference, the complete description is 

repeated here. It should be a good species for correlation of the Oligocene.

Test trochoid, somewhat longer than broad, dorsally 

flattened or somewhat concave, ventrally convex 

except for a slight depression in the umbilical region, 

periphery lobulate, rounded in edge view; chambers 

distinct in the adult whorl, four or five in number, 

increasing somewhat in length as added, on the ventral 

side strongly convex, on the dorsal side with the outer 

half convex, the inner half strongly excavated; sutures 

distinct, depressed, strongly curved dorsally, les^1 so 

ventrally; wall very coarsely perforate; aperture or the 

ventral side, nearly'umbilical, with a rather thick projecting lip above the aperture itself. Length, 0.30 

millimeter; breadth, 0.20 millimeter; thickness, 0.15 to 

0.18 millimeter.

The types are from the Byram marl, 30 feet above a, 

limestone ledge, bottom of hill 011 road ascending from 

Waltersville (Vicksburg), Miss., to National Cemetery.

It is interesting to find this distinctive species in our 

material from Alabama. It is from bed 5. No other 

record of it has been made since the original description, 

which is repeated above.

This common Oligocene species, known from all the 

formations of the Vicksburg of Mississippi, is found in 

our present material from beds 3, 4, 5, and 6. The 

early stages may be confused with E. albamensis 

Cushman and McGlamery, but the later development 

of the two species is distinctive.

This species is recorded from all marine formations 

of the Oligocene Vicksburg group of the Gulf Coastal 

Plain, occurring in Mississippi, Alabama, Florida, and 

Texas. It is recorded from the Oligocene Meson 

formation of Mexico and has lately been recorded by 

Bermudez from the upper Eocene of Cuba. It is found 

in considerable numbers in our material and is represented in all six beds. It seems strange that it should 

not have appeared in our material from Choctaw Bluff, 

but was apparently absent there.

Indo-Pacific species. They occur in beds 1, 3, 4, 5, 

and 6. Two specimens are figured. It has already 

been recorded from the upper formations of the Oligocene of Mississippi and the Marianna limestone of 

Alabama. Hadley records it from the Oligocene of 

Cuba.

Family ORBITOIDIDAE

Genus LEPIDOCYCLINA Gttmbel, 1868

Specimens of orbitoid Foraminifera were submitted 

to Dr. T. Wayland Vaughan, who has given us the 

following notes in regard to them:

Red 2.

Lepidocyclina sp., species not identifiable. 

Bed 6.

Lepidocyclina (Eulepidina) cf. L. undosa Cushman var.

More discoid than L. undosa, not so selliform. 

Geological horizon: Oligocene, middle or upper—not 

lower Oligocene.

I have ground three ppecimens from bed 6 to the equatorial 

plane and have exposed the embryonic and equatorial chambers 

in each. Two of the specimens ground on one side are not at all 

saddle-shaped, as are most specimens of Lepidocyclina undosa, but 

in the same lot there are other specimens that are selliform. 

Although the flat specimens are not typical L. undosa, I should 

hesitate to apply another name to them.—T. W. V.
