Attachment J Assessment of Existing Paleontologic Data Along with Field Survey Results for the Jonah Field
Attachment J Assessment of Existing Paleontologic Data Along with Field Survey Results for the Jonah Field June 12, 2007 ABSTRACT This is compilation of a technical analysis of existing paleontological data and a limited, selective paleontological field survey of the geologic bedrock formations that will be impacted on Federal lands by construction associated with energy development in the Jonah Field, Sublette County, Wyoming. The field survey was done on approximately 20% of the field, primarily where good bedrock was exposed or where there were existing, debris piles from recent construction. Some potentially rich areas were inaccessible due to biological restrictions. Heavily vegetated areas were not examined. All locality data are compiled in the separate confidential appendix D. Uinta Paleontological Associates Inc. was contracted to do this work through EnCana Oil & Gas Inc. In addition BP and Ultra Resources are partners in this project as they also have holdings in the Jonah Field. For this project, we reviewed a variety of geologic maps for the area (approximately 47 sections); none of maps have a scale better than 1:100,000. The Wyoming 1:500,000 geology map (Love and Christiansen, 1985) reveals two Eocene geologic formations with four members mapped within or near the Jonah Field (Wasatch – Alkali Creek and Main Body; Green River – Laney and Wilkins Peak members). In addition, Winterfeld’s 1997 paleontology report for the proposed Jonah Field II Project was reviewed carefully. After considerable review of the literature and museum data, it became obvious that the portion of the mapped Alkali Creek Member in the Jonah Field is probably misinterpreted. -

Condylarthra, Mammalia) by ROBERT M

I0024 NUMBER 246I APRIL 30, 1971 Deciduous Dentition of the Early Tertiary Phenacodontidae (Condylarthra, Mammalia) BY ROBERT M. WEST1 INTRODUCTION Isolated deciduous teeth are frustrating and often confusing finds for mammalian paleontologists. Accurate identification and interpretation of these teeth depend upon positive association with permanent teeth. Unfortunately deciduous teeth commonly are found separately, because they were either shed by the living animal in the course of maturation or they were lost after the death of a subadult individual. Additionally, rapid wear often removes most of their distinguishing features early in life, so many are virtually featureless, whereas permanent teeth, at a similar age, retain much of the surface topography. In the process of a study of the Paleocene to Eocene condylarth family Phenacodontidae, I encountered a large number of deciduous teeth both isolated and in jaws and frequently associated with at least one permanent tooth. The present paper describes and illustrates the decidu- ous premolar dentitions, as far as known, of three common genera of phenacodont condylarths (Tetraclaenodon, Phenacodus, and Ectocion). The presence of some deciduous teeth in place in jaws allows examina- tion of their relationships with one another and with the permanent teeth. It is also possible, under favorable circumstances, to postulate the sequence of replacement of deciduous teeth and eruption of the perma- nent teeth. 1Assistant Professor of Biology, Adelphi University, Garden City, New York. 2 AMERICAN MUSEUM NOVITATES NO. 2461 All measurements are given in millimeters, and the important features of the deciduous teeth are shown in the outline drawing (fig. -
Early Eocene Fossils Suggest That the Mammalian Order Perissodactyla Originated in India
ARTICLE Received 7 Jul 2014 | Accepted 15 Oct 2014 | Published 20 Nov 2014 DOI: 10.1038/ncomms6570 Early Eocene fossils suggest that the mammalian order Perissodactyla originated in India Kenneth D. Rose1, Luke T. Holbrook2, Rajendra S. Rana3, Kishor Kumar4, Katrina E. Jones1, Heather E. Ahrens1, Pieter Missiaen5, Ashok Sahni6 & Thierry Smith7 Cambaytheres (Cambaytherium, Nakusia and Kalitherium) are recently discovered early Eocene placental mammals from the Indo–Pakistan region. They have been assigned to either Perissodactyla (the clade including horses, tapirs and rhinos, which is a member of the superorder Laurasiatheria) or Anthracobunidae, an obscure family that has been variously considered artiodactyls or perissodactyls, but most recently placed at the base of Proboscidea or of Tethytheria (Proboscidea þ Sirenia, superorder Afrotheria). Here we report new dental, cranial and postcranial fossils of Cambaytherium, from the Cambay Shale Formation, Gujarat, India (B54.5 Myr). These fossils demonstrate that cambaytheres occupy a pivotal position as the sister taxon of Perissodactyla, thereby providing insight on the phylogenetic and biogeographic origin of Perissodactyla. The presence of the sister group of perissodactyls in western India near or before the time of collision suggests that Perissodactyla may have originated on the Indian Plate during its final drift toward Asia. 1 Center for Functional Anatomy & Evolution, Johns Hopkins University School of Medicine, 1830 E.

ATKINS2 INTRODUCTION Fossil vertebrates from the upper part of the Bridger Formation (Mid- dle Eocene) at Tabernacle Butte in the northeastern part of the Green River Basin have been collected and studied primarily by personnel of the University of Wyoming and of the American Museum of Natural History. P. 0. McGrew and others (1959) described the stratigraphy and the fauna known at that time. Supplementary reports have since been published by Simpson (1959a, 1959b), M. C. McKenna and Simp- son (1959), and McKenna, P. Robinson, and D. W. Taylor (1962). The present paper adds data on mammalian material collected by the Ameri- can Museum of Natural History parties in 1959 and 1967. During the senior author's study of the phenacodont condylarths in the American Museum of Natural History collection, McKenna pointed out a specimen recovered from the "Hyopsodus Hill" locality (Locality 5 of McGrew and others) in 1967. Examination of this specimen confirmed its tentative identification as Phenacodus, a genus not previously known to have survived later than the time of the Lost Cabin fauna (early 1 Department of Geological and Geophysical Sciences, Princeton University, New Jersey; present address: Department of Biology, Adelphi University, Garden City, New York. 2 Department of Biological Sciences, Columbia University, New York. 2 AMERICAN MUSEUM NOVITATES NO. 2404 Eocene) in North America. -

The mollusc fauna is strongly indicative of varied tropical estuarine environments probably vegetated with mangroves, but may also contain material derived from underlying mangrove facies. Both coastal marine and terrestrial mollusc and vertebrate faunas are also represented. The terrestrial community contained indicators of subtropical rainforest lowland with broad river banks and lakes, but some reworking of materials seems likely. The early-middle Ypresian Falun de Pourcy probably reflected ongoing estuarine/mangrove conditions that characterised the late Sparnacian period. Preliminary species lists of mollusc and vertebrate fossils are given, together with a comparison of mollusc feeding guilds to those of a modern Indo-Pacific estuary system. -
Walking with Whales.Pdf
news and views Walking with whales Christian de Muizon Whales must have evolved from land-based mammals, but fossil evidence of some of the steps in between has been patchy. Newly discovered skeletons with legs fill in the gaps. n page 277 of this issue, Thewissen and colleagues1 describe their discovery of u.p. Opartial fossil skeletons from the earliest cetaceans — a group of mammals that today consists of whales, porpoises and dolphins. The fossils, which are some 50 million years Diacodexis old and were found in Pakistan, take us a huge step forwards in understanding the origins and evolutionary relationships of Phenacodus Pachyaena whales. Until now, the limbs of all known u.p. early cetaceans reflected an amphibious or 2–6 wholly aquatic lifestyle . But the newly Pakicetus discovered fossils show that the first whales l.p. were fully terrestrial, and were even efficient runners. They also reveal that cetaceans are Pakicetus Diacodexis Sus more closely related to the oldest known even-toed ungulates — a group of hoofed Ambulocetus mammals that includes cows, hippos, pigs, Figure 2 Ankle bones (astragali) of hoofed 17 camels and giraffes — than to any other Pelvis and mammals and primitive whales.

Eberle The Paleocene–Eocene Thermal Maximum (PETM) represents a rapid global warming at the Paleocene–Eocene (PE) boundary. Research by others in Wyoming’s Bighorn Basin has demonstrated that certain mammalian taxa (e.g., the ‘condylarths’ Ectocion and Copecion, and the perissodactyl Sifrhippus [=Hyracotherium]) experienced a decrease in body size during the height of the PETM. To date, this phenomenon has not yet been documented in North American PE boundary-spanning mammalian faunas outside of the Bighorn Basin. -
Paleocene Mammals and Albert Silberling
Paleocene Mammals and Albert Silberling Albert Silberling in the Redrock Mountain area near Harlowton, 1949. he town of Harlowton is located in the Fort Union Geological Photo courtesy of Jackie Silberling Formation, which was created about 65 million years ago, shortly after the dinosaur extinction. This once shallow inland sea was Tformed from rivers originating in the southwestern mountain slopes of Montana. These rivers transferred and deposited sediment collected from the swampy, subtropical eastern coastal plains into the shallow sea. As the rivers shifted over time, swamp vegetation and peat were covered with thick deposits of sand, silt, and clay, which would later form coal. These deposits cemented and compacted into sandstone, siltstone, and mudstone—soft materials that easily erode—leaving few outcrops of more weather-resistant rocks. The area surrounding Harlowton is also famous for its Paleocene fossils. In 1902, Princeton University paleontologist Earl Douglass and Albert Silberling, a local homesteader and self-taught paleontologist, discovered the fossil remains of primitive mammals in a quarry southwest of Harlowton. Paleontologists excavated that quarry and three others over the next four decades and these sites yielded the remains of at least 23 species, including a squirrel-like animal called Ptilodus, the most successful of all mammals.

It co- existed with massive sauropods, such as the Apatosaurus and Diplodocus, Geo-Facts: as well as the meat-eating Allosaurus. -
