Vertebrate Paleontology Of The Koum Basin, Northern Cameroon, And Archosaurian Paleobiogeography In The Early Cretaceous, John Deforest Congleton Jr.

Earth Sciences Theses and Dissertations

The Koum basin is located in West Africa and is a half­graben filled with Cretaceous and younger sediments. It formed in response to tectonic stresses that preceded the development of the Benue trough and the final connection of the North and South Atlantic Oceans. The Cretaceous sediments, up to 3000 meters thick, represent lacustrine, fluvial, and alluvial fan deposits, and suggest an axially­drained half-graben sedimentation model.

Archosaur fossils recovered from the eastern Koum basin include the teeth of two terrestrial crocodylians (cf. Araripesuchus wegeneri and cf. Sebecosuchia) teeth of sauropod and two kinds of theropod dinosaurs (cf. Spinosauridae and Theropoda …

Stromatolites Of The Lower Cambrian Deep Spring Formation; Mount Dunfee, Esmeralda County, Nevada, Lynn Oliver

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Middle Member of the Lower Cambrian Deep Spring Formation at Mount Dunfee, Nevada contains a diverse assemblage of stromatolites that formed on a tide- and storm-dominated, siliciclastic-influenced, carbonate shelf. The stromatolites formed in a shallow subtidal environment within and near active oolite shoals under strongly focused currents. The stromatolites occur in four different lithofacies: (1) bioherms of digitate stromatolites, (2) bioherms and biostromes of inclined stromatolites, (3) isolated forms of massive and hemispheroidal stromatolites, and (4) a biostrome of cryptomicrobial boundstones. The first three lithofacies are interpreted as microbial reefs. They had topographic relief, formed in active agitated waters, …

Efficiency In Collecting Fossils, Kenneth M. Ball, Leo Carson Davis

Journal of the Arkansas Academy of Science

Two hundred seventy-two kilograms of sediments and fossils were collected from 1 meter square plots on lake beach and river gravel bars to compare the efficiency of surface collecting with that of intensive laboratory processing. Collecting fossils by visual inspection of the outcrop required an average of 14 minutes 56 seconds per square meter and resulted in 319 vertebrate and 1320 invertebrate fossils. The ratio of time spent collecting and processing sediments to time spent in surface collecting fossils was 4.66:1. The ratio of invertebrates produced by the intensive laboratory process to invertebrates produced by surface collecting was 4.80:1. Vertebrate …

Middle Eocene Foraminifera From The Piney Point Formation Of The Virginia And Maryland Coastal Plain, Megan S. Jones

OES Theses and Dissertations

This study examines the foraminiferal fauna, both benthic and planktonic, of the outcropping (45 samples) and subsurface (31 samples) middle Eocene Piney Point Formation in Virginia and Maryland. The primary objective of this study is to further refine the depositional history of the Salisbury Embayment which is represented by the middle Eocene Piney Point Formation. Ninety-six species of benthic and planktonic foraminifera were identified in this study. Of these, several are characteristic of the middle Eocene: Asterigerina texana, Hanzawaia danvillensis, Ceratobulimina exima, Cibicides westi, Chiloguembelitria columbiana, C. stavensis, Testacarinata inconspicua and Pseudohastigerina wilcoxensislmicra. While these were relatively abundant, diagnostic middle …
