It was becoming more arid, the tropical forests were disappearing from the northern latitudes, and there was an increase in seasonality. Research of the Chadronian (37- 33.7mya) in the Great Plains region of North America has documented the persistence of several mammalian taxa (e.g. primates) that are extinct in other parts of North America. -
The Natural Science Underlying Big History
Review Article [Accepted for publication: The Scientific World Journal, v2014, 41 pages, article ID 384912; printed in June 2014 http://dx.doi.org/10.1155/2014/384912] The Natural Science Underlying Big History Eric J. Chaisson Harvard-Smithsonian Center for Astrophysics Harvard University, Cambridge, Massachusetts 02138 USA [email protected] Abstract Nature’s many varied complex systems—including galaxies, stars, planets, life, and society—are islands of order within the increasingly disordered Universe. All organized systems are subject to physical, biological or cultural evolution, which together comprise the grander interdisciplinary subject of cosmic evolution. A wealth of observational data supports the hypothesis that increasingly complex systems evolve unceasingly, uncaringly, and unpredictably from big bang to humankind. This is global history greatly extended, big history with a scientific basis, and natural history broadly portrayed across ~14 billion years of time. Human beings and our cultural inventions are not special, unique, or apart from Nature; rather, we are an integral part of a universal evolutionary process connecting all such complex systems throughout space and time. Such evolution writ large has significant potential to unify the natural sciences into a holistic understanding of who we are and whence we came. No new science (beyond frontier, non-equilibrium thermodynamics) is needed to describe cosmic evolution’s major milestones at a deep and empirical level. Quantitative models and experimental tests imply that a remarkable simplicity underlies the emergence and growth of complexity for a wide spectrum of known and diverse systems. Energy is a principal facilitator of the rising complexity of ordered systems within the expanding Universe; energy flows are as central to life and society as they are to stars and galaxies. -

So far, the reconstruction of its locomotor behavior has varied from terrestrial bounding to semi-arboreal scansoriality and squirrel-like arboreal walking, bounding and claw climbing. In order to elucidate substrate preferences and positional behavior of this extinct archontan, the present study investigates quantitatively selected postcranial characters of the ulna, radius, femur, and ungual pha- langes of P. tricuspidens and P. n .sp. from three sites (Cernay-les-Reims, Berru, Le Quesnoy) in the Paris Basin, France. These species of Plesiadapis was compared to squirrels of different locomotor habits in terms of selected functional indices that were further explored through a Principal Components Analysis (PCA), and a Discriminant Functions Analysis (DFA). The indices treated the relative olecranon height, form of ulnar shaft, shape and depth of radial head, shape of femoral distal end, shape of femoral trochlea, and dis- tal wedging of ungual phalanx, and placed Plesiadapis well within arboreal quadrupedal, clambering, and claw climbing squirrels. -
New Fossil Discovery Illuminates the Lives of the Earliest Primates 24 February 2021
New fossil discovery illuminates the lives of the earliest primates 24 February 2021 Royal Society Open Science. "This discovery is exciting because it represents the oldest dated occurrence of archaic primates in the fossil record," Chester said. "It adds to our understanding of how the earliest primates separated themselves from their competitors following the demise of the dinosaurs." Chester and Gregory Wilson Mantilla, Burke Museum Curator of Vertebrate Paleontology and University of Washington biology professor, were co-leads on this study, where the team analyzed fossilized teeth found in the Hell Creek area of northeastern Montana. The fossils, now part of the collections at the University of California Museum of Paleontology, Berkeley, are estimated to be 65.9 Shortly after the extinction of the dinosaurs, the earliest million years old, about 105,000 to 139,000 years known archaic primates, such as the newly described after the mass extinction event. species Purgatorius mckeeveri shown in the foreground, quickly set themselves apart from their competition -- like Based on the age of the fossils, the team estimates the archaic ungulate mammal on the forest floor -- by that the ancestor of all primates (the group specializing in an omnivorous diet including fruit found including plesiadapiforms and today's primates up in the trees. Credit: Andrey Atuchin such as lemurs, monkeys, and apes) likely emerged by the Late Cretaceous—and lived alongside large dinosaurs. Stephen Chester, an assistant professor of anthropology and paleontologist at the Graduate Center, CUNY and Brooklyn College, was part of a team of 10 researchers from across the United States who analyzed several fossils of Purgatorius, the oldest genus in a group of the earliest-known primates called plesiadapiforms. -

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. -

Barnes Contributions in Honor of David P. Whistler WANG | BARNES 900 Exposition Boulevard Los Angeles, California 90007 Natural History Museum of Los Angeles County Science Series 41 May 28, 2008 Paleocene primates from the Goler Formation of the Mojave Desert in California Donald L. Lofgren,1 James G. Honey,2 Malcolm C. McKenna,2,{,2 Robert L. Zondervan,3 and Erin E. Smith3 ABSTRACT. Recent collecting efforts in the Goler Formation in California’s Mojave Desert have yielded new records of turtles, rays, lizards, crocodilians, and mammals, including the primates Paromomys depressidens Gidley, 1923; Ignacius frugivorus Matthew and Granger, 1921; Plesiadapis cf. P. anceps; and Plesiadapis cf. P. churchilli. The species of Plesiadapis Gervais, 1877, indicate that Member 4b of the Goler Formation is Tiffanian. In correlation with Tiffanian (Ti) lineage zones, Plesiadapis cf. P. anceps indicates that the Laudate Discovery Site and Edentulous Jaw Site are Ti2–Ti3 and Plesiadapis cf. P. churchilli indicates that Primate Gulch is Ti4. The presence of Paromomys Gidley, 1923, at the Laudate Discovery Site suggests that the Goler Formation occurrence is the youngest known for the genus. Fossils from Member 3 and the lower part of Member 4 indicate a possible marine influence as Goler Formation sediments accumulated. On the basis of these specimens and a previously documented occurrence of marine invertebrates in Member 4d, the Goler Basin probably was in close proximity to the ocean throughout much of its existence.
