1985-1992 Abstracts

A progress report on late Quaternary benthic foraminifera from the central continental shelf of western Canada

Patterson, R.T. (1989)

Geological Survey of Canada Bulletin 396, Contributions to Paleontology, p. 229-265.

Forty-two species of benthic foraminifera and planktonic foraminifera were identified in 296 samples from the Shell Anglo Murrelet L-15. Harlequin D-86, and Osprey D-36 wells of the Queen Charlotte Basin.  Two distinct temporal and four distinct depositional environments are recognizable.  Interpretations are, however, limited by major zones of faunal non-recovery, and sparse foraminiferal data.
In the upper parts of the Harlequin D-86 and Osprey D-36 wells, a well developed, essentially modern boreal benthic foraminiferal community was identified.  Because all species found in this zone range from at least the Pliocene and are extant, biostratigraphic resolution finer than the Pliocene-Quaternary is not possible.
Seismic data indicate that the upper and lower faunal zones identified in all three wells are separated by regional uncomformities that occurred in the Late Miocene and Pliocene.
The presence of characteristic neritic fauna and, in Murrelet L-15, three coal seams, indicate alternating shallow marine and nonmarine conditions during deposition.  The sediments in the lower parts of the wells were probably deposited no later than middle Miocene (Luisian Stage).
The Miocene foraminifers from the Harlequin D-86 and Murrelet L-15 wells are extensively diagenetically altered.  This suggests an increase in thermal and geochemical maturity northward in the Basin.


Patterson, R.T. (1990)

Geological Survey of Canada, Part F, Paper 90-1F

This ongoing study contributes to deciphering the paleogeography of the western shelf of Canada and the understanding of the potential hazards to offshore hydrocarbon exploration, Preliminary qualitative analysis of 39 samples extracted from 4 piston cones and 1 vibro-core has yielded a fauna of 95 species of benthic foraminifera. One of these species, Nanosylvanella palmulina Patterson, is new and not referable to any previously described genus.


Tortaguttus, a new unilocular foraminiferal genus

Barrick, R., Beverage, A., Patterson, R.T. and Schubert, J.

Tulane Studies in Geology and Paleontology, v. 22.

A new genus of unilocular foraminifera, Tortaguttus, is described, with Entosolenia sigmoidella var. timmsensis Cushman and Gray, 1946, as type species. The distinctive twisted carinae and radial aperture differentiate the new genus from other genera of the subfamily Ellipsolageninae A. Silvestri, 1923.


Re-examination of the statistical methods used to determine the number of point counts needed for micropaleontological quantitative research

Patterson, R.T. and Fishbein, E.

Journal of Paleontology, v. 63 (2).

Currently some controversy exists in the micropaleontological community concerning the statistically correct number of counts required for quantitative examinations, particularly with respect to the effect of variations in the number ofspedes between samples and the significance of varying fractional abundances on the reliability of results, This analysis of the various statistical methods used to determine the number of required counts has shown that the number of species has no relationship to the number of counts required to measure accurately fractional abundances, As part of the study, logarithmic contours plotting percentage abundance against the total number of specimens, which provide abundance errors at a 95 percent confidence level, have been generated. The plot is displayed logarithmically to emphasize the significance of rare microfossil elements that dominate most assemblages, and which are important in many paleoenvironmental studies. Based on the plot, it is recommended that researchers utilize counts of at least 50 for indicator species having a fractional abundance of approximately 50 percent or greater; 300 counts for species which comprise approximately 10 percent of a sample; 500-1,000 counts for species that make up 5 percent of a sample; and counts of several thousand for defining species that comprise 1 percent ofa sample. It is important to note, however, that where similar biofacies are involved, higher counts are required to accurately distinguish them. It is also recommended that researchers include fractional error abundances with their estimated abundances to provide an indication of their accuracy.


Reexamination of the benthic foraminiferal fauna from a Late Pleistocene marine terrace deposit near Goleta, California

Barrick, R., Beverage, A., Patterson, R.T. and Schubert, J.

Journal of Paleontology, v. 63 (3).

A benthic foraminiferal fauna of 39 species was quantitatively examined from a late Pleistocene marine terrace deposit near Goleta, California. This foraminiferal fauna, dominated by Cribroelphidium microgranulosum, Buccella tenerrima, Bulirninella elegantissima, and Cribroelphidium tumidurn, is presently most common in cool, shallow (less than 12 m, but usually 0-5 m) subtidal environments north of Point Conception, California. This indicates slightly cooler water temperatures during the time of deposition than found near Goleta today, and agrees closely with the results of a previous paleoenvironmental interpretation of the section based on molluscan fossils.


Eight new unilocular foraminiferal genera

Patterson, R.T. and Richardson, R.

Transactions of the American Microscopical Society, v. 107 (3).

Although varied and diverse, unilocular foraminifera are among the least understood group of the foraminifera. Part of the problem has been the inadequate number of taxonomic divisions within this diverse group. A new taxonomic framework has been proposed to make the group more useful to taxonomists and stratigraphers. Several additional new genera are proposed herein. The new genera Hyalinonetrion (type species H. sahulense n. sp.) and Pygmaeoseistron (type species P. hispidulum) are included in the Lageninae. Five new genera also are included in the Ellipsolageninae. These include Cursina n. gen. (type species C. adornata n. sp.), Exsculptina n. gen. (type species L. sidebottomi), Favulina n. gen. (type species Entosolenia hexagona), Homalohedra n. gen. (type species Lagena guntheri), and Laculatina n. gen. (type species Lagena quadrilatera striatula). Bifarilaminella n. gen. (type species Lagena advena Cushman) is included in the Sipholageninae. Three additional new species are described: Favultna epibathra n. sp., Pytine petaloskelis n. sp., and Sipholagena structiloides n. sp.


Globulospinella, a new unilocular foraminiferal genus, and designation of a neotype for Palliolatella avita Patterson and Richardson

Patterson, R.T.

Journal of Paleontology, v. 107 (3).

Globulospinella, a new foraminiferal genus of the Lageninae, differs from other genera of the subfamily by having a surface sculpture consisting of numerous elongate processes on a globular test. Globulospinella porcuspina n. sp., the type species, is described. A neotype for Palliolatella avita Patterson and Richardson, the type species of Palliolatella Patterson and Richardson, is designated.


A taxonomic revision of the unilocular foraminifera

Patterson, R.T. and Richardson, R.

Journal of Foraminiferal Research, v. 17 (3).

Unilocular foraminifera are varied and diverse, yet among the least understood gronp of the foraminifera. Part of the problem has been the inadequate number of taxonomic divisions within this varied group. We propose a new taxonomic framework to make the group more useful to taxonomists and stratigraphers alike, and to eventually lead to a better understanding of the group as a whole.

Rather than subdividing the unilocular foraminifera into more than one family, we reinstate the family Lagenidae Reuss, 1862, to include all unilocular forms, and recognize three subfamilies. The first subfamily, Lageninae Reuss, 1862, encompasses genera that lack an entosolenian tube, including Lagena Walker and Jacob, and the reinstated Procerolagena Puri. The second subfamily, Ellipsolageninae Silvestri, 1923, accommodates genera with an entosolenian tube at some stage of the life cycle, including Oolina d'Orbigny, Cushmanina Jones, Fissurina Reuss, Galwayella Patterson and Pettis, I renita Jones, Lagenosolenia McCulloch, Parafissurina Parr, Pseudofissurina Jones, Pseudoolina Jones, Pseudosolenina Jones, Solenina Jones, Ventrostoma Schnjtker, Walterparria Jones, and Wiesnerina Jones. Four new genera are also included in the Ellipsolagenidae: Duplella (type species D. apexadina, n. sp.), Palliolatella (type species P. arita, n. sp.), Pristinosceptrella (type species P. hispida, n. sp.), and Vasicostella (type species V. helophoromarginata (Jones)). We also describe two additional new species belonging to this subfamily: Vasicostella singulara and Wiesnerina carinata.

We propose a new third subfamily, Sipholageninae, to include those unilocular genera with double walls connected by a network of pillars. This subfamily contains Sipholagena Moncharmont-Zei and Sgarrella and Pytine Moncharmont-Zei and Sgarrella.


Four new foraminiferal (protozoa) genera from the Rio Grande Rise, Southwest Atlantic Ocean

Patterson, R.T.

Transactions of the American Microscopical Society, v. 106 (2).

Based on wall microstructure as indicated in thin section and other morphologic features, some new foraminiferal genera are proposed. Magnesoina, a new genus of the Prolixoplectidae, differs from other genera of the family in having the final chambers uniserially arranged. The type species of the genus is Listerella antillarum, The family Prolixoplectidae is emended to include genera with a late uniserial stage. Strtctocostella, a new genus of the Stilostomellidae, differs from other genera of the family by its costate test. The type species of the genus is Ellipsonodosaria modesta prolata. Torulumbonina, a new genus of the Nodosariinae, with type species Frondicularia btkintensis, differs from other genera of the subfamily by its non-palmate chamber arrangement and knob-encircled aperture. Pleuroskelidion, a new genus of the Pleurostomellidae, differs from other genera of the family by its costate test. The type species is Pleuroskelidion unda n. sp.


Arcellaceans and foraminifera from Lake Tecopa, and eastern California Pleistocene Lake

Patterson, R.T.

Journal of Foraminiferal Research, v. 17 (4).

An assemblage of 22 foraminiferal species and a single species of Arcellacea is documented from Lake Tecopa, a dry Pleistocene lake bed in southeastern California. As the lake was never in direct contact with the ocean, the close affinity of this assemblage to the fauna inhabiting coastal marine waters off California suggests colonization via avian transport. The presence of a well developed foraminiferal fauna in Lake Tecopa augments previous paleolimnological interpretations based on fresh water ostracode and diatom data and also provided by petrographic analysis. The presence of foraminifera in Pleistocene lake sediments also provides further evidence that foraminifera are not always indicative of marine facies.


Galwayella, a new foraminiferal genus and new names for two foraminiferal homonyms

Patterson, R.T. and Pettis, R.

Journal of Foraminiferal Research, v. 16 (1).

Galwayella, a new genus of the Oolininae differs from other genera of this family by its distinct trigonal cross-section. The type species of the new genus is Lagena trigonoelliptica Balkwill and Millett, 1884.

New names are proposed for two homonyms in the Oolininae and Nodosariinae: Lagenosolenia incomposita for Lagena marginata (Montagu) var. spinifera Earland, and Dentalina ariena for Dentalina intorta (Dervieux).


Amplectoductina, a new foraminiferal genus in the Siphogenerinoididae:

Patterson, R.T.

Tulane Studies in Geology and Paleontology, v. 16 (1).

Amplectoductina, a new genus of the Tubulogenerininae, is distinguished by its entirely uniserial chamber arrangement. The type of the new genus is A mplectaductina carnatolintra.


1986 Karreriella obturaculoides, a new foraminiferal species

Patterson, R.T.

Tulane Studies in Geology and Paleontology, v. 5 (2).

In Quaternary samples from the Rio Grande Rise in the southwest Atlantic Ocean, a benthic agglutinated foraminiferal species occurs that has also been observed in other medium to deep-water Atlantic (Cushman, 1922), Gulf of Mexico (Flint, 1897), Indian Ocean (Boltovskoy, 1978) and Pacific (Taylor, in preparation) localities. It has been variously referred to Gaudryina filiformis Berthelin, G. pseudofiliformis Cushman and G. bradyi Cushman. However, a careful examination of type illustrations indicates no affinity of the present specimens to these, or any other described species. Thus, a new species is required to accommodate these specimens.


Globofissurella and Cerebrina, two new foraminiferal genera in the Lagenidae

Patterson, R.T.

Journal of Micropalaeontology, v. 5 (2).

Globofissurella, a new genus of Oolininae, differs from other genera of the subfamily by its costate test and fissurine aperture. The type species Globofissurella scotti sp. nov., and an additional species, Globofissurella bulabrum sp. nov. are also described. Cerebrina gen. nov., type species Cerebrina perplexa sp. novo differs from other genera of the subfamily Oolininae by its reticulate surface sculpture and fissurine aperture.


Occurrence and reliability of internal morphologic features in some Glandulinidae (Foraminiferida)

Taylor, S., Patterson, R.T., Choi, H.

Journal of Foraminiferal Research, v. 15 (1).

Specimens of some glandulinid foraminifers have been critically examined to assess the validity of recently defined genera and their separation from Glandulina. The genus Tappanella, with T. arctica as type species, differs from Glandulina in the prominent biserial stage of the specimens examined. The genus Euglandulina, type species E. inusitata, is here restricted to those species with an asymmetrical entosolenian tube, attached to one wall of the terminal chamber. The formerly invalid genus Barnardina and type species B. thanetana have been validated by provision of a diagnosis and description. Glandulinoides, type species G. yunnanensis, from the Triassic of China, differs from these genera in the short centrally located entosolenian tube and absence of a biserial early stage.


Arcellaceans ("Thecamoebians") in small lakes of New Brunswick and Nova Scotia: modern distribution and Holocene stratigraphic changes

Patterson, R.T., MacKinnon, K., Scott, D., Medioli, F.

Journal of Foraminiferal Research, v. 15 (2).

Sediment-water interface samples from five lakes in New Brunswick and three lakes in Nova Scotia were quantitatively examined for both living and total populations of Arcellaceans. Two major assemblages (I and II) were recognized, both characterized by three main species: Difflugia oblonga, Lagenodifflugia vas, and Pontigulasia compressa. Assemblage I is divided into five sub-assemblages characterized by occurrences of minor species. Assemblage II basically has only three species with low abundances. The assemblage variations within Assemblage I are difficult to link with specific variables since we know relatively little about individual species. However, individual occurrences of two species can be linked to specific conditions: Difflugia bidens relates to increased sediment input and Difflugia tricuspis occurs with high concentrations of floating algae. The division between Assemblage I and II appears to be a function of seasonal temperatures. The high diversity Assemblage I occurs where summer temperatures reach values greater than 18C (that is, above the thermocline) while Assemblage II occurs below the thermocline where temperatures do not exceed 6C. Oxygen values in both assemblages are the same and, as in Lake Erie, low oxygen values do not appear to be a limiting factor. To complement the surface studies, cores from six of these lakes were also examined. Most lakes were formerly marine basins when sea level was much higher and the marine freshwater transition demonstrated the sharpest assemblage changes. Centropyxis aculeata usually dominated the transition sections. Arcellacean assemblages illustrated few changes once freshwater conditions were established in New Brunswick even though climatic changes are known in the same interval. However, assemblages in the Nova Scotia lakes changed sharply below the surface with D. tricuspis becoming much more common; this indicates more floating algae in these lakes in pre-modern times. Most of the species encountered here have been illustrated by us previously; however, three species found here were not illustrated in our Lake Erie study-Lesquereusia spiralis, Difflugia urceolata elongata, and Difflugia urens, n. sp.-and are fully illustrated here together with all the other species.


Abditodentrix, a new foraminiferal genus in the family Bolivinitidae

Patterson, R.T.

Journal of Foraminiferal Research, v. 15 (2).

Abditodentrix, a new genus of the Bolivinitidae, differs from other genera of the family by its distinct truncate margin, reticulate ornamentation, and reduced toothplate. The type species of the new genus is Abditodentrix asketocomptella, n. sp.
