The extinction occurred in two pulses, with a brief rise of a recovery fauna (Hirnantia fauna) between pulses. The extinction patterns of trilobites are studied in this thesis in order to better understand selectivity of the -

Available Generic Names for Trilobites

Brisbane. ISSN0079-8835. Aconsolidated list of available generic names introduced since the beginning of the binomial nomenclature system for trilobites is presented for the first time. Each entry is accompanied by the author and date of availability, by the name of the type species, by a lithostratigraphic or biostratigraphic and geographic reference for the type species, by a family assignment and by an age indication of the type species at the Period level (e.g. MCAM, LDEV). A second listing of these names is taxonomically arranged in families with the families listed alphabetically, higher level classification being outside the scope of this work. We also provide a list of names that have apparently been applied to trilobites but which remain nomina nuda within the ICZN definition. Peter A.

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. -

Khan and 3Abdul Ghaffar 1Zoology department, Quaid-e-Azam campus, Punjab University, Lahore, Punjab, Pakistan 2Zoology Department, GC University, Faisalabad, Punjab, Pakistan 3Department of Meteorology, COMSATS Institute of Information Technology (CIIT), Islamabad ABSTRACT Fossil site Dhok Bun Ameer Khatoon (32o 47' 26.4" N, 72° 55' 35.7" E) yielded a significant amount of mammalian assemblage including two families of even-toed fossil mammal (Giraffidae, and Bovidae) and one family of odd-toed (Rhinocerotidae) of the Late Miocene (Samiullah, 2011). This newly discovered site has well exposed Chinji and Nagri formation and has dated approximately 14.2-9.5 Ma. This age agrees with the divergence of different mammalian genera. Sedimentological evidence of the site supports that this is deposited in locustrine or fluvial environment, as Chinji formation is composed primarily of mud-stone while the Nagri formation is sand dominated. Palaeoenvironmental data indicates that Miocene climate of Pakistan was probably be monsoonal as there is now a days. Mostly the genera recovered from this site resemble with the overlying younger Dhok Pathan formation of the Siwaliks while the size variation in dentition is taxonomically important for vertebrate evolutionary point of view and this is the main reason to conduct this study at this specific site to add additional information in the field of Palaeontology. A detailed study of fossils mammals found in Miocene rocks exposed at Dhok Bun Ameer Khatoon was carried out.
