The first paper published on the TWs Point Foram-
inifera was by Dr. Rufus Bagg in 1912. The material for the
preaent thesis was collected from the south-east part of San
Pedro, California, along the blwf facing the harbor, fram
the same locality from which Dr. Bagg obtained his material.
The writer has identiffed one hundred and thirty-aeven dif-
ferent species and varieties, in addition to one new species,
and seven species which seem to be new, but of which there
is not a large enough series to be sure, In a comparison
with the Timms Point Foraminifera1 genera listed by Rankin
and Laiming, it was found that they had listed seven genera
not found by the writer, and that the writer had listed
twenty genera not found by Rankin and Lairming, The Australian
Kalimnan (Lower Pliocene) Foraminifera were found to be quite
different from the Timms Point Forminifera. The writer
believes that the Timms Point Foraminifera indicate a cold
epoah in the Pleistocene of Southern Califormia. Each species
and variety of the Foraminifera has been mounted in an indi-
vidual slide and filed with the Geology Departanent of the
University of Southern Californfa,
The Foraminifera of the
Timms Point Formation at San Pedro,
Los Angeles County, California
INTRODUCTION
Bsneml Purpose:
he general purpose of this paper 3.8 to study the
Forsminifera of the Tinrms Point formation. The material
irosn that formation which the writer examined was found to
be very rich in Foraminifera, with abundant aponge-apicules
ud aome Pelecypoda and Oatracoda. The individual forms were
Zdentified by means of literature describing and picturing
late qertiary and Quaternary Foraminifera. The collection of
Timms Point Foraminifera in the Department of Geologg of the
Wversity was also of value in identifying the forms. The
Foraminifera thus identified give a general idea of the Fora-
rfniiaral fauna of the whole Tinnns Point formation, as samples
of material from different levels of the formation were
examined. The work was carried on between September, 1937,
and Hay, 1938, at the University of Southern California.
The area examined, (see map), is located in the south-
eastern part of the town of San Pedro, Los Angeles County,
California, just east of the south end of Harbor Boulevard,
along the bluff facing the harbor, not far from the Nav Land-
. It is part of the sea cliff extending from a point
near Point Fermin northward along the east side of the town.

Specific Purpoae:
The specific purpose of this paper is to list all the
species and varieties found, both identified and new species,
Individuals of each specles and variety have been mounted in
separate slides and filed with the Department of Geology of
the University of Southern California, These slides have
been arranged according to the Cuahman arrangement of families
and genera. Also, the relative abundance of the forms is in-
dicated by the number of form of the different species and
varieties mounted in the slides, That is, one form indicates
that that species or variety is very rare; two, that it is
rare; three, that it is present; four, that it is common, and
five, that it is abundant. These Tinans Point Foraminifera,
furthemore, have been compared as far as was possible with
Australian Kalimnan (Lower Pliocene) Foramlnifera, which the
writer obtained by examination of Australian material from
Dr, A. J, TieJe'a oollection, Also, these Foraminifera have
been compared with the Tims Point Foraminifera1 genera found
by Rankin and Laiming. Finally, the writer has briefly oon-
sidered the climatic probzem of the California Early Pleis-
tocene with special reference to the Foraminifera of' the
Tinus Point formation,
Acknowledgements:
The writer wishes 'to express his apprecfation to
Dr. A, J, Tieje, Professor of Geology at the University of
Southern California, for suggesting the problem and for advice
4
and constructive criticism, Thanks are also due Dr, Thomas
Clements, head of the Department of Oeology at tbe same uni-
versity, for advice in completing the paper,
The writer also
wishes to express his thanks to Mr, Wilbur De Rankin, chief
micropaleontologiat at the Continental Oil Company, Los Ange-
lea, for material from the Timms Point formation, The writer
is also indebted to Dr, Joseph A, Cushman, Director of the
Cushman Laboratory for Foraminifera1 Research at Sharon,
Massachusetts, for identifying some of the species listed,
Historical Review:
Little has hitherto been written on this topic, The
first and very incomplete paper on the Foraminifera of the
Timms Point formation was published in 1912 by Dr, Rufus M,
Bagg, ~r.,' in the United States Geological Survey Bulletin
513, Although some Foraminifera are described, most of the
generic names used are now obsolete, and only one of the
pictured form is from Timu8 Point. Oalloway and wisslerS2
in a 1927 paper on the Lomita Wrry Foraminifera, list the
Lomita forms which also occur in the Timms Point fornation,

also list numerous Foraminifera from the Tbma Point forma-
tion, but only by genera. In a thesis presented in 1929 to
the Department of Geology of the University of Southern Cali-
fornia, William He ~arrandl also lists the Tinans Point Fora-
minifera directly transcribed frcnn Wissler. Cric1nnays2 in a
paper on Deadman's Island stratigraphy, gives a short list
of Foraminifera. Alex ~lark,3 in a paper on the Tinrme Point
formation, discusses only the megafauna. Manley Platland, 4
in a paper on the temperature and depth-distribution of some
Southern California fossil and Recent Foraminifera, lists
Foraminifera ranging fram the Lower Pliocene to the present,
some of which are conteunporaneous with the Timms Point forms.

LIST OF FORAMINIFERA FOUND
Tbe following is a list of the Foraminifera found in
the Tim Point formation by the writer, They are listed
according to the arrangement of families and genera by Dr,
Joseph A, Cushman, and the new species are described and pic-
tured, A few references are given for each Identified form
wherever possible, but no attempt has been made to aake the
reference list complete.

COMPARISON WITH THE RANKIN-LAIIYII[lVG LIST
We D, Rankln and B. G, Laiming in a paper on the Foram-
inifera of Tinrms Point and Deadman's lslandB1 list a total of
one hundred and eighty-eight different species,
all, however,
unnamed, and listed merely as, for example, Lagena, 15
species, The writer has listed one hundred and forty-five
different apeciea, eight of which are thought to be new.
Rankin and Laiming also list seven genera not found by the
writer. These are, one apeciea each of Acervulina, Clavulina,
Cuneolina, Lenticulina and Nodogenerina, two species of
Cassidulinoides, and five of Dentalina. The writer, on the
other hand, has listed twenty genera not found by Rankin and
Lakaing. These include one species each of Cancris, Dorothia,
Dyocibicides, Clbicidella, Ehrenbergina, Globulina, Massilina,
Miliolinella, Plarrularia, Pseudopolgmorphina, Pyrulina, Sig-
mmorphina, Spiroloculina, and Valvulineria, two species of
Gtuttulina, Planulina, Pyrgoella, and Robertina, four species
of Angulogerina and five of Discorbis, The large number of
genera not found by Rankin and Laiming but found by the wri-
ter is, in part, due to the fact that some new genera have
been erected since tneir paper was written.

Pliocene) formation as far as the writerIs inveatigationa
go,
are not like those of the Californian Lower Pleistocene,
though, to same extent the Foraminifera of Californiafs Lower
Pliocene are like its Lower Pleistocene. For instance, the
families most numerous in the Australian material are the La-
genidae, Rotaliidae, and Nonlonidae, whereas those most
mrmerous at Ths Point are the Cassidulinidae, Anomalinldae,
and Miliolldae. F'urthermore, some genera are fouqd in the
the Australian material that are not found in the California
Pleistocene, such as Siphogenerinoldes, Operculina, and Amphis-
tegina.
Climatic Zmpllcations of the Foraminifera:
The Australian Foraminifera indicate a warmer climate
than that of the Californian Lower Pleistocene.
The numerous
Nonionidae in the Australian material would indicate Zone 2,

This would imply a bottom temperature of from 21.43 degrees

temperature of from 13.20 degrees Centigrade to 8.50 degrees
Centigrade,
Such a view would agree with many previous views.
Accorbillg to Ralph
the mollusc evidence indicates
subboreal conditions in Southern California in the Upper
Pliocene to Lower Pleistocene, He also states: %atest
Pleistocene faunas of the same regions are of a type more
tropical than those now inhabiting the shores of the Pacific
2
coast of the United States."
James P, Smith seems to agree
with this in a paper on the climatic relations of the Tert-
iary and Quaternary faunas of California, He writes: n~
subboreal temperature extended down nearly to San Diego in
the Lower ~uaternary." Also: "The Upper San Pedro fauna
is southern in kinship, with many species now living only in
the Panama region." Alex ~lark,3 in his paper on the Timms
Point formation, states that there are exposed typical cool-
water fauna above the silts and a warmer-water transitional
fauna below, Manley Natland, however, states that there is
a gradual warming of the waters in which the sedimentary
beds were deposited from the Lower Pliocene on up, this implying

that the change in temperature is entirely due to the shal-
lowing of the sea. He thus seems to neglect the Pleistocene
glacial periods, so that the above statement suggests a much
too sweeping generalization.
On the whole, the Foraminifera of the Tbms Point
formation are so abundant in Casaidulina (a cool-water genus),
at all stratigraphic levels, that the writer believes the
Timms Point formation was almost certainly laid down during
a cold portion of the Pleistocene, probably during a glacial
epoch.

Abstract (if available)

Abstract The first paper published on the Times Point Foraminifera was by Dr. Rufus Bagg in 1912. The material for the present thesis was collected from the south-east part of San Pedro, California, along the bluff facing the harbor, from the same locality from which Dr. Bagg obtained his material. The writer has identifed one hundred and thirty-seven different species and varieties, in addition to one new species, and seven species which seem to be new, but of which thereis not a large enough series to be sure, In a comparison with the Timms Point Foraminiferal genera listed by Rankin and Laiming, it was found that they had listed seven genera not found by the writer, and that the writer had listed twenty genera not found by Rankin and Laiming, The Australian Kalimnan (Lower Pliocene) Foraminifera were found to be quite different from the Timms Point Forminifera. The writer believes that the Timms Point Foraminifera indicate a coldepoch in the Pleistocene of Southern California. Each species and variety of the Foraminifera has been mounted in an individual slide and filed with the Geology Department of the University of Southern California.
