PREFACE.

The Foraminifera described in this bulletin were collected by the 

author from the Greensand series of the Upper Cretaceous of New 

Jersey, and include representatives from the Matawan, Moninouth, Bancocas, and Manasquan formations. They were determined, described, 

and presented as a thesis at the Johns Hopkins University for the 

degree of doctor of philosophy in the year 1895, and the types are 

deposited in the geological museum of that university, at Baltimore, 

Maryland. Some additional results of later study have yielded a 

number of interesting forms which are here described for the first 

time.

The author wishes to express his gratitude to Prof. W. B. Clark, who 

has kindly assisted in the work, and under whose direction the investigation has been carried on.

Acknowledgments are due the following persons who have furnished 

material for comparative study: Dr. G. Brown Goode, of Washington; 

Prof. Charles W. Johnson, of the Wagner Free Institute of Science, 

Philadelphia; Mr. T. W. Stauton and Dr. W. H. Dall, of Washington; 

Prof. Alonzo Linn, of Washington and Jefferson College, Pennsylvania; 

and Mr. Lewis Woolman, of Philadelphia.

The writer is also under great obligation to Mr. Frederick Chapman 

and Charles D. Sherborn, of London, England, for their kind assistance 

iu determining doubtful forms, and for their approval of the new species 

herein described.

THE CRETACEOUS FORAMINIFERA OF NEW JERSEY.

By R. M. BAGG, Jr.

INTRODUCTION.

The fossil Foraminifera of America have never received much attention, although some of the most distinguished European paleontologists have been at work upon this group for many years, and have 

published numerous monographs and special reports upon it. Within 

the last few years, however, several short papers have appeared upon 

the Cretaceous Forarninifera of Canada, Minnesota, New Jersey, and 

Alabama.

The first report upon the Cretaceous Foraminifera of Canada was 

published by Dr. G. M. Dawsou, 1 in the Canadian Naturalist for 1874. 

Four species of Foraminifera are described and figured in this report, 

namely: JMscorMna globularis, Planorbulina ariminensis, Textidaria glcil)- 

ulosa, and Tcxtularia pygmcva. These forms were discovered in the 

Cretaceous rocks of Pembina, Manitoba, which bear some resemblance 

to the "chalk" of Nebraska.

J. B. Tyrrell 2 has recognized in the Niobrara limestone of Manitoba 

some 25 different species of Foraminifera, a tabulated list of which 

appeared in the Transactions of the Royal Society of Canada and in 

the Annual Report of the Geological Survey of Canada :| for 1890 and 

1891.

Sixteen species of Foraminifera from the Cretaceous bowlder clays 

of central Minnesota were described and figured by Woodward and 

Thomas 4 in 1885. This report was reprinted, with additions of fossils 

from Nebraska and Illinois, in the Final Report of the Geological Survey of Minnesota.5

12 CRETACEOUS FORAMINIFERA OF NEW JERSEY. [BULL. 88.

The Journal of the 'New York Microscopical Society for April, 1S90, 1 

contains a short article on the Cretaceous Foraminifera of New Jersey, 

by Dr. Anthony Woodward. This paper is entitled Synopsis of the 

Cretaceous Foraininifera of New Jersey, and contains only a review 

of previous investigations. A second part, however, appeared in the 

same journal for 1S94,2 in which Dr. /Woodward describes 58 different 

species of Foraminifera from the New Jersey marl beds.

Still more recently a tabulated list of the Cretaceous and Tertiary 

Foraminifera of Alabama has been published in a special report of the 

Geological Survey of Alabama/1

The present memoir is a more thorough account than has previously 

been given of the Cretaceous Forainiuifera from the marl beds of New 

Jersey. It was presented as a thesis at the Johns Hopkins University 

in May, 1895, but has been somewhat revised and enlarged, and contains descriptions of a number of species from the upper beds of the 

Matawan formation, which are here given for the first time. The latter 

were collected by the author during the last summer, while he was 

engaged in geological mapping in southern New Jersey. The specimens were obtained at Marshalltown, Salem County, New Jersey, in a 

very fossiliferous bed of sandy marl, which has been dug as a fertilizer.

A large amount of material has been collected and examined in the 

preparation of this report, from the following localities:

Monmouth formation (Navesink division, or lower marl bed): Atlantic Highlands, Freehold, and Cream Eidge.

Itancocas formation (middle marl bed): Blue Ball, New Egypt, Viricentown, Swedesboro, Timber Creek, and Harrisonville; also from a 

well boring at Quinton.

Manasquan formation (upper marl bed, lower part): Viucentown.

It was hoped that a careful study of the Foraminifera found in these 

various marl beds might not only result in the addition of many new 

species to our American Cretaceous, but might also serve as a means of 

identification of these strata. Such has been found to be the case, 

although the fact that certain species are present in several or all the 

beds has been established, while many of them have continued through 

deposits of later age and are'found in existing oceans.4

The writer believes that the localities from which the fossils were collected for study are as typical as any which might have been chosen, 

although further investigation in many new localities can hardly fail to 

yield additional results.

The excellent state of preservation and the large size of many of the 

species are most striking and bear witness to the favorable conditions 

for their existence in the late Cretaceous sea.

 -.Specimens of three types have been analyzed, two of calcareous and 

one of arenaceous character, in order to determine the amount of silica

It is an interesting fact bearing on the origin of greensand that the 

writer has frequently found shells of Foramiuifera filled with glauconite. 

This has been especially noticeable in Polymorphina communis, which 

in some cases, where the shell is broken away, shows the interior filled 

with light-green glauconite still bearing upon its outer surface the 

smooth impress of the shell.

Many Cristellarije are partially filled with a light-brown clay suggesting the early stage in the formation of the glauconite grain. Upon 

a few grains of glauconite I have found clinging to the central portion 

remnants of the original shell, while the glauconite still shows an internal cast of the shell.

It is perhaps rather remarkable that among so many grains of glauconite so few perfect casts of Foraminifera are found and so small a 

number of intermediate stages, but it must be remembered that the 

shell wall of the forms is always thin and easily destroyed through 

solution in the percolating waters in such porous beds. Even among 

the Lamellibranchiata and Gasteropoda casts of the shells are much 

more abundant than well-preserved shells, except the heavier, ponderous 

shells of Exogyra, costata and Gryphcea vesicularis. From the size of 

the glauconite grains and the peculiarity of their shape it is pro.bable 

that the glauconite has grown by accretion around an original nucleus, 

so that the outline of the delicate shells is only exceptionally preserved.

Transverse sections of the glaucouite grains show a difference in 

color and texture between the internal and external parts, the inner

It is not the object of this paper to enter into any discussion of the 

much-disputed problem of the origin of'greeusand. This subject has 

been discussed by numerous writers, especially of late by Murray and 

Eenard 2 in their report upon the deep-sea deposits obtained by the 

Challenger Expedition. A statement of the results brought out by 

this investigation, with a short review of former theories, has been 

published by Prof. W. B. Clark 3 in his discussion of the origin of the 

greeusand of New Jersey. That both organic and inorganic materials 

must be present for the formation of greeusand has been established, 

but just what proportion of each is necessary is not so readily determined. The inorganic material occurring in the New Jersey marl beds 

is chiefly quartz and mica, and is supposed to have been derived from 

the crystalline rocks of Pennsylvania and northern New Jersey.

The greensands differ in the size of the sand grains, in the amount of 

rounding, and in the proportion of sand to glaucouite. In the Manasquan formation (lower part of upper marl bed) there is proportionately 

more glauconite than in any of the other beds, while the quartz grains 

are more rounded than in the lower beds of the Monmouth formation, 

though perhaps less so in the upper or Eedbauk series. So large an 

amount of quartz sand is present in this latter bed that glaucouite holds 

only a secondary place. For this reason no Foraminifera are known 

from the Eedbank sands, although it is probable that the upper and 

lower portions of the bed will furnish some when more thoroughly 

examined.

The Navesink marls contain more Foraminifera than the Manasquan 

beds, and in a somewhat better state of preservation, but it is in the 

limestone layer of the Eancocas formation (middle marl bed) that the 

greatest abundance of forms is found. This deposit, frequently consolidated, is made up of great quantities of bryozoan shells and vast numbers of perfectly preserved Foraminifera. Seventy-nine species have 

been determined from this horizon alone. Four species are'present in 

all four marl beds, namely: Nodosaria obliqua (Linne"), Nodosaria polygona Eeuss, Nodosaria zippei Eeuss, and Truncatulina lobatula (Walker 

and Jacob).

HISTORICAL SUMMARY.

The value of the greensand marls for fertilizing purposes has been 

known in Few Jersey for more than a century. In 1768 a laborer, while 

digging a ditch in a meadow near Marlboro, threw out a substance 

which was pronounced to be marl. Some of this marl was spread upon 

the land with good results, but no particular attention seems to have 

been paid to the discovery until the year 1811, when its value began to 

be appreciated.

The discovery of fossils in the marl beds was made soon after, and 

in 1820 some of these fossils were described by Say, 1 and others by 

Mortou 2 in 1829. . The first mention of Foraininifera was made by Isaac Lea 3 in 1833, 

in his Contributions to Geology, when he described Flabellina xagittaria as Palmula sayittaria from the Cretaceous deposit of Timber 

Creek, New Jersey, in which he considered the form a new genus of 

the family Spherulacea of Blainville. The genus Palmula Mr. Lea considered as intermediate between the genus Saracenaria of Defrance 

and the genus Textularia of the same author. This same species was 

described by Dr. S. G. Mortou 4 in 1842 as Planularia cuneata.

In the American Journal of Science for 1841 5 Prof. J. W. Bailey 

gives a brief note on. the discovery of fossil Foraininifera in New Jersey, 

and states that "a large portion of the calcareous rock defined by 

Prof. H. D. Eogers(i as the third formation of the upper secondary is 

made up of great quantities of microscopic shells belonging to the 

Foraininifera."

Sir Charles Lyell,7 on his visit to America in the year 1841, noticed 

the occurrence of Forammifera in the Cretaceous marl beds of New 

Jersey, and mentioned three very common types, Cristellaria, Eotalia 

(Kotalina), and Nodosaria.

In his Origin of Greensand, and its Formation in the Oceans of 

 the Present Epoch, 8 Prof. J. W. Bailey refers to the deposits at Mullica 

Hill and Mount Holly, New Jersey, as being very rich in greensand 

casts of Polythalamia.

Mr. W. M. Gabbj in Descriptions of New Species of American Tertiary and Cretaceous Fossils, a describes one of the NodosariiB from. 

Mullica Hill as a new species under the name Dentalina pulckra, but 

which is known to be Nodosaria zippei Eeuss.

microscopic organisms was published in 1861 by Prof. A. B. Eeuss, 1 one 

of the most distinguished of European paleontologists. In this article, 

entitled Die Foraminiferen der senonischen Griindsandes vou New 

Jersey, Professor Eeuss described some 28 different species of Foraniinifera, but mentioned neither the* horizon nor the localities from 

which they were obtained. While a few of these forms were figured in 

this report, the majority are given in other works.

Hermann von Credner 2 in 1870 published an article entitled Die 

Kreide von New Jersey, which contained a general review of the 

Cretaceous of New Jersey. In this report two Foraminifera from the 

Bryozoa bed at Brownville, Flabellina cordata Eeuss and Nodosaria 

sulcata Niisson, are described.

Subsequent to Professor Credner's report in 1870 no work was done 

upon the Foraminifera of New Jersey until the year 1894, when Dr. 

Woodward :i published the second part of his Cretaceous Foraminifera 

of New Jersey. In this report some 58 species of Foraminifera from 

Timber Creek, Mullica Hill, New Egypt, and Bruere's pits, on Crosswicks Creek, are described but not figured.

The material investigated at the geological laboratory of the Johns 

Hopkins University has furnished nearly twice as many species as previously reported, and six of these are considered to be new. A preliminary report of this investigation, containing a description of the new 

forms and a tabulated list of other species identified, was published 

by the author 4 in 1895.

The Foraminifera described in this bulletin are deposited in the geological museum at the Johns Hopkins University, Baltimore, Maryland.

BIBLIOGRAPHY.

Within the last ten years several bibliographies of the Foraminifera 

have appeared, which have been of invaluable assistance in the preparation of this report. The best bibliography Avhich has yet been published is that of Prof. Charles D. Sherborn, entitled A Bibliography 

of the Foraminifera, Kecent and Fossil, from 1565 to 1888. (London, 

1888.) This excellent catalogue is based upon the bibliography given 

by Prof. H. B. Brady in the Challenger report, but has been greatly 

enlarged and revised.

Another bibliography, less exhaustive, compiled by Dr. Anthony 

Woodward, was published in the Fourteenth Annual Keport of the 

Geological and Natural History Survey of Minnesota for the year 1885.

There has lately been published in the Smithsonian Miscellaneous 

Collections An Index to the Genera and Species of the Foraminifera, 

by Charles D. Sherborn. This exhaustive work, invaluable to all students of Foraminifera, is in two parts, and forms a portion of Volume 

XXXVII of the Smithsonian reports. The first part was published in 

November, 1893, and included all names from A to N, while the second 

portion, published in 1890, completes the alphabetic list of forms from 

N to Z. The most distinguished specialists in the Foraminifera have 

been, consulted by Professor Sherborn in the preparation of this laborious Avprk, and too much praise can not be given the author for the completeness and accuracy of its contents.

The following is a list of works consulted in the preparation of this 

report. 'No attempt is made to give a complete bibliography; only

DESCRIPTIVE TERMS.

The following descriptive terms, adopted in this memoir, are taken, 

with some modification, from the report on the Recent Foraminifera of 

Great Britain, by Prof. W. C. Williamson. 1 The figures employed have 

been copied, but the lettering has been changed.

The length is measured in the direction or axis of growth, as indicated by the line A B in fig. 1 of PI. I, and^the breadth by a line at 

right angles to the former one, C D in the same figure.

The above terms are applicable for evolute and convolute types, but 

in certain forms, either monothalamous and rounded or when the 

growth of chambers is around a central aperture, it is more convenient, 

to use the term diameter.

The separate divisions of a shell or test are spoken of as segments, 

designated in fig. 1 of PI. I as P, I, andU, of which P is the primordial 

and U the ultimate segment, while I, holding an intermediate position, 

is known as an intermediate segment. That part of the external surface nearest the end of the ultimate segment is called the anterior 

margin (fig. 1, a), while the opposite end is referred to as the posterior 

margin (fig. 1, p). These terms have a direct reference to the direction 

of growth.

The various segments are separated from one another by partitions 

called septa, and these are usually indicated externally by more or less 

definite constrictions known as septal lines (fig. 1, s). In old age these 

constrictions often become filled up and appear as ridges instead of 

depressions. The septal plane is the superficial area of each septum 

and corresponds in dimensions with the entire breadth of the constricted 

portion of the shell (fig. 1, sp).

Each .septum is provided °with one or more openings known as septal 

apertures, which serve as a means of communication between contiguous segments. The perforation of the anterior end of the ultimate 

segment is spoken of as the oral aperture (fig. 1, o a).

The different views of the shell are referred to as the anterior, lateral, 

and periphero-lateral aspects. The anterior aspect is seen by looking 

down upon the septal plane of the ultimate segment; the lateral aspect 

shows the shell from one side, as in fig. 1; while the periphero-lateral 

aspect is seen in depressed forms where the shell is viewed from its 

thin edge, as in fig. 3 of PI. II. When the segments are arranged in a 

complete circuit around the primordial cell they constitute a convolution. Each convolution joins a contiguous one by a spiral line called 

the spiral suture (PI. I, fig. 2, m). In the simplest case these convolutions 

are arranged in a single plane, but in more coinplex types each convo1 On the Recent ForaminLfcra of Great Britain, Ray Society, London, 1858, pp. 14-18.
26 . CRETACEOUS FORAMINJFERA OF NEW JERSEY. [BULL. 88.

lution is formed in a different plane, and a trockoid type of shell results, 

as in Discorbina (fig. 4). The Avord " rotaliforin " is used to express a 

form in which all of the segments are visible upon the superior surface, 

but only those of the last convolution are visible upon the inferior 

surface.

Each side of the shell in convolute types presents a lateral surface 

(fig. 3, L L). The sides of the shell at right angles to these lateral surfaces constitute the peripheral margin (fig. 3, x x}. The margin is very 

varied in shape, and the angle formed by its outline is called tlie peripheral angle.

The depression formed in the center of the shell is caLed the umbilicus. Sometimes, instead of being depressed the early chambers are 

raised or elevated into a sort of boss by deposit of exogenous material, 

but the area is always referred to as the umbilical area, whether raised 

or depressed.

The terms superior and inferior lateral surface are constantly referred 

to and should be clearly understood. When a form continues its convolutions in a single plane both sides remain similar and there is no 

distinction between the upper and lower lateral surfaces, but when the 

coils are arranged spirally, as in trochoid types, there is a difference 

bet\veen the surfaces and it becomes necessary to indicate by the terms 

"superior" and "inferior" the surface referred to.

The term superior lateral surface (fig. 4, S L S) is the one in which 

the primordial segment is situated, Avhile the opposite side, in which 

the form is extending its growth, is the inferior lateral surface (fig. 4, 

I L S). There are some exceptions to this rule, as, for example, in certain Truncatulina types, which are approximately fiat upon the side 

that bears the primordial segment, as if the shell were cut in halves, 

the line of division passing through the center of the primordial segment. In such cases the lower (flat) surface becomes the superior 

lateral side.

The term distal end refers to the portion of the shell which carries the 

oral aperture and is usually farthest removed from the primordial segment. The portion of the shell in which the primordial segment is 

situated is called the proximal end.

It is often necessary to speak of a given type of shell, and therefore 

the following terms are employed in this report:

1. Nodosarian (PI. I, fig. 1). Chambers typically arranged in a 

straight, row.

2. Nautiloid (PI. I, figs. 2 and 3). Chambers wound in a horizontal 

manner, forming an equilateral spire.

3. Trochoid (PI. I, fig. 4). Chambers wound around one side of the 

primordial segment in an inequilateral spire.

4. Textularian (PI. I, fig. 5). Chambers arranged alternately in an 

elongated series (biserial).

5. Milioline (PI. I, fig. 6). Chambers wound spirally about an 

imaginary axis.

This is a very common form at Yinceutown, and is frequently found 

adhering to Flabcllina sagittaria, although often occurring on other 

shell fragments. Although the primordial chamber is generally the 

smallest and the ultimate the largest, there is no regularity of arrangement in regard to size of the chambers.

It was with some difficulty that the position of this form, was determined. The structure of the shell substance alone separates it from 

Trochammina irregularis Carpenter,2 but solution of the shell in hydrochloric acid failed to reveal any trace of arenaceous or siliceous material, although in some ca^es there A^as an inner coating of amorphous 

material remaining insoluble in the acid.

A form, similar to the one under discussion is figured by Quenstedt3 

and described by him as Bullopora rostrata in the following words: 

"This consists of simple, small, dark hemispheres, united with each 

other through lengthened tubes. This tube often projects from the end 

cell like a beak, whence I have given it its name. Generally the pustules (chambers) increase in size, with now and then smaller ones 

between, while the primordial cell is similar to those succeeding." 

This species is described by Schwager 4 as Placopsilina rostrata, and is 

placed under the calcareous perforate division of the Dentaloidea.

In the original description of the genus Placopsiliua 1 no mention is 

made of the nature of the test, whether of arenaceous or calcareous composition, but later authorities (Brady 2 ) consider the genus under arenaceous types of the Lituolidoe.

The tubulated structure of 'the genus Webbina, simulating the arenaceous Trochainrninai, is quite striking, and its calcareous composition 

in this case led to a discussion by Dr. W. J. Sollas,3 "On the perforate 

character of the genus Webbitia," etc., and the later establishment of 

a new genus, Vitrewebbina, by Frederick Chapman,4 which I have 

adopted as a solution of the difficulty presented by this isomorphous 

form.

This beautiful species is one of the very largest forms of Foraminifera found in the New Jersey Cretaceous marl beds, and was described 

by Gabb as early as 1860, under the name Dentalina pulchra. Owing 

to its great length it is very easily broken, so that only a few of the 

largest specimens are perfect. It was very Avell described by Keuss in 

1844 (loc. cit.), who said that its length was sometimes 1£ inches, the 

number of chambers twenty to thirty, the costai seven to fourteen, and 

that there were secondary riblets occasionally set in between the main 

costse and running a short distance along the surface of the shell.

Eeuss also pointed out the similarity of Nodosaria, septemcostata and 

N. undecimcostata Geinitz, and considered the two latter as identical 

with N. zippei. Dr. Anthony Woodward considers this species identical with N. raphanistrum, but the two species are sufficiently distinct 

to justify the retention of the original name given by Professor Beuss.

This species has a very wide geological range and distribution in the 

Cretaceous, and occurs in every marl bed of Few Jersey.

In the large amount of material examined in the preparation of this 

report an interesting case of dimorphism was observed in one of the 

specimens of Nodosaria zippei. The shell which has been previously 

referred to begins as a textularian with two chambers side by side, 

each bearing the same number of costte as the original form and united 

above into a straight typical nodosarian chamber. It was found in the 

green marl of Blue Ball, where the Nodosariai are so perfectly preserved that rnucronate forms still retain their spines in almost perfect 

condition.

Locality. Manasquan formation, Viucentown, New Jersey.

Geological distribution. Cretaceous to Kecent.

This form is commonly associated with Truncatulina lobatula or 

Truncatulina ungeriana, or with both, and has a similar distribution.

Truncatulina liaidingerii Brady, 1884; Chal. Kept., Vol. IX, p. 663, PI. XCV, fig. 7, a-c.

Test circular, biconvex, trochoid; volutions three, chambers marked 

by slightly depressed septa on inferior side, about twelve segments in 

the last convolution; aperture a small marginal slit.

Diameter, 0.58 mm.

Locality. Kancocas formation, Vincentown, New Jersey.

Geological distribution. Cretaceous to Kecent.

The above species is similar to Truncatulina ungeriana, but differs 

from it in being more vaulted and less depressed at the umbilicus. It 

is also a smaller form and is not so abundant, being rather rare in the 

middle marl bed. There is, furthermore, no distinct groove following 

the whorls upon the superior side, and the perforations are smaller 

than in Truncatulina ungeriana.

Test plano-convex, moderately vaulted; last volution consisting of 

seven or eight chambers, with very slightly depressed septa; septa more 

curved upon the superior (flat) surface; aperture a small, neatly shaped 

arch at the margin of the ultimate segment.

Geological distribution. Carboniferous to Recent.

The above species shows great variation. Professor Brady considers 

that the more convex varieties merge into Truncatulina refulgens, while 

flattened forms resemble Truncatulina wuellerstorji. The regular-built 

convex varieties constitute the Truncatulina boueana of d'Orbigny, and 

the less regular the Truncatulina variabilis of the same author,

sutures somewhat depressed upon the inferior (vaulted) surface; peripheral margin sharp; aperture an inframarginal opening near the base of 

the ultimate segment.

Diameter, 0.5 mm. '

Locality. Manasquan formation (?), Vincentown, New Jersey.

Geological distribution. Cretaceous (Upper 1?) to Recent.

There is a possibility that this is an Uocene fossil, as it was obtained 

from some of the uppermost greeusand of the New Jersey Cretaceous, 

which carries a number of Eocene fossils, together with some of late 

Cretaceous age. The specimens came from the upper marl bed at Vincentown, and only a very few forms were found.

umbilicus, consisting of three convolutions. The last volution consists of from ten to twelve limbate chambers. Septa arched; aperture 

a m'edian semilunar slit.

Diameter, 0.78 mm.

Locality. Rancocas formation, New Egypt, New Jersey; Manasquan

Pliocene deposits of Kar Nicobar by Schwager, but does not mention 

its earlier occurrence. It is an intermediate form between Truncatulina lobatula and Anomalina ariminensis.

separated by straight septal lines below; aperture elongate, slightly 

removed from the margin.

Diameter, 0.45 mm.

Locality. Raucocas formation, Blue Ball, Timber Creek, New Jersey.

Geological distribution. Cretaceous to Recent.

This is not a common species, but was described by Prof. A. E. 

Eeuss under the name Eotalina nitida, which he considered to bo a 

young form of Eotalina umbilicata d'Orbigny. Dr. W. B. Carpenter 

considers that the Eotalina umbilicata of the Chalk is identical with 

Eotalina soldanii of the Vienna Tertiaries. Prof. H. B. Brady states 

that Pulvinulina micheliniana has its isomorph in Truncatulina refulgens, 

from which species it is distinguished by the more or less excavated 

umbilicus and the projecting apical margins of the segments. In the 

Challenger Eeport, however, Eotalina nitida is not given under the 

synonyms of Pulvinulina micheliniana, but Dr. Woodward has so considered it in his report on the Cretaceous Foraminifera of New Jersey, 

and it seems probable that this view is correct.

PULVINULINA KETICULATA Eeuss, var. CARINATA Bagg.
