Nesomomys is an extinct genus of omomyid that inhabited Turkey during the Eocene epoch. It is a monotypic genus known from a single species, N. bunodens. [1]
Anseranatidae, the magpie-geese, is a biological family of waterbirds. The only living species, the magpie goose, is a resident breeder in northern Australia and in southern New Guinea.
Haplorhini, the haplorhines or the "dry-nosed" primates is a suborder of primates containing the tarsiers and the simians, as sister of the Strepsirrhini ("moist-nosed"). The name is sometimes spelled Haplorrhini. The simians include catarrhines, and the platyrrhines.
Omomyidae is a group of early primates that radiated during the Eocene epoch between about 55 to 34 million years ago (mya). Fossil omomyids are found in North America, Europe & Asia, making it one of two groups of Eocene primates with a geographic distribution spanning holarctic continents, the other being the adapids. Early representatives of the Omomyidae and Adapidae appear suddenly at the beginning of the Eocene in North America, Europe, and Asia, and are the earliest known crown primates.
Tarsiiformes are a group of primates that once ranged across Europe, northern Africa, Asia, and North America, but whose extant species are all found in the islands of Southeast Asia. Tarsiers are the only living members of the infraorder; other members of Tarsiidae include the extinct Tarsius eocaenus from the Eocene, and Tarsius thailandicus from the Miocene. Two extinct genera, Xanthorhysis and Afrotarsius, are considered to be close relatives of the living tarsiers, and are generally classified within Tarsiiformes, with the former grouped within family Tarsiidae, and the latter listed as incertae sedis (undefined). Omomyids are generally considered to be extinct relatives, or even ancestors, of the living tarsiers, and are often classified within Tarsiiformes.
Plotopteridae is an extinct family of flightless seabirds with uncertain placement, generally considered as member of order Suliformes. They exhibited remarkable convergent evolution with the penguins, particularly with the now extinct giant penguins. That they lived in the North Pacific, the other side of the world from the penguins, has led to them being described at times as the Northern Hemisphere's penguins, though they were not closely related. More recent studies have shown, however, that the shoulder-girdle, forelimb and sternum of plotopterids differ significantly from those of penguins, so comparisons in terms of function may not be entirely accurate. Plotopterids are regarded as closely related to Anhingidae (darters) and Phalacrocoracidae (cormorants). On the other hand, there is a theory that this group may have a common ancestor with penguins due to the similarity of forelimb and brain morphology. However, the endocast morphology of stem group Sphenisciformes differs from both Plotopteridae and modern penguins.
Necrolemur is a small bodied omomyid with body mass estimations ranging from 114–346 g (4.0–12.2 oz). Necrolemur’s teeth feature broad basins and blunt cusps, suggesting their diet consisted of mostly soft fruit, though examination of microwear patterns suggests that populations from lower latitudes also consumed insects and gums.
Palaeophis is an extinct genus of marine snake that is the type genus of the extinct snake family Palaeophiidae.
Shoshonius is an extinct genus of omomyid primate that lived during the Eocene. Specimens identified as Shoshonius have been found exclusively in central Wyoming and the genus currently includes two species, Shoshonius cooperi, described by Granger in 1910, and Shoshonius bowni, described by Honey in 1990.
Teilhardina is an extinct marmoset-like omomyid primate that lived in Europe, North America and Asia during the Early Eocene epoch, about 56-47 million years ago. The paleontologist George Gaylord Simpson named it after the French paleontologist, Jesuit and philosopher Teilhard de Chardin.
Altanius is a genus of extinct primates found in the early Eocene of Mongolia. Though its phylogenetic relationship is questionable, many have placed it as either a primitive omomyid or as a member of the sister group to both adapoids and omomyids. The genus is represented by one species, Altanius orlovi, estimated to weigh about 10–30 g (0.35–1.1 oz) from relatively well-known and complete dental and facial characteristics.
Altiatlasius is an extinct genus of mammal, which may have been the oldest known primate, dating to the Late Paleocene from Morocco. The only species, Altiatlasius koulchii, was described in 1990.
Eremosuchus is an extinct genus of sebecosuchian mesoeucrocodylian. Fossils have been found from El Kohol, Algeria of Eocene age. It had serrated, ziphodont teeth.
K. Christopher Beard is an American paleontologist, an expert on the primate fossil record and a 2000 MacArthur Fellowship "Genius" Award Winner. Beard's research is reshaping critical debates about the evolutionary origins of mammals, including primates, routinely questioning current thinking about their geographical origins. Dr. Beard is the former Curator of the Carnegie Museum of Natural History, and Mary R. Dawson Chair of Vertebrate Paleontology, at University of Pittsburgh. He is currently Distinguished Foundation Professor, Senior Curator at the University of Kansas. He was co-author with Dan Gebo about an extinct primate from China. Dr. Beard also authored the book The Hunt for the Dawn Monkey: Unearthing the Origins of Monkeys, Apes and Humans. Beard was also part of the research teams that discovered Teilhardina, the earliest primate ever found in North America, and Eosimias, one of the earliest higher primates yet discovered. He worked with NASA to scan a Tyrannosaurus rex skull. Beard received his PhD from the Functional Anatomy and Evolution Program at Johns Hopkins University School of Medicine in 1989.
Lavocatavis is an extinct genus of prehistoric bird from the Eocene of Algeria. A fossilized femur was described from the Glib Zegdou Formation in 2011 and is the only known specimen of Lavocatavis. The species was designated L. africana.
Anaptomorphinae is a pre-historic group of primates known from Eocene fossils in North America and Europe and later periods of Paleocene Asia, and are a sub-family of omomyids. The anaptomorphines is a paraphyletic group consisting of the two tribes Trogolemurini and Anaptomorphini. Anaptomorphine radiation in Wyoming, one of the most detailed records of changes within populations and between species in the fossil record, has provided remarkable evidence of transitional fossils.
Cynohyaenodon is an extinct paraphyletic genus of placental mammals from extinct family Hyaenodontidae that lived from the early to middle Eocene in Europe.
Lesmesodon is an extinct genus of placental mammals from extinct family Proviverridae within extinct superfamily Hyaenodontoidea, that lived during the Early to Middle Eocene. It was found in France and in the Messel Pit in Germany. Lesmesodon was a weasel-sized carnivorous mammal.
Bownomomys was an early marmoset-like primate that lived in North America during the Early Eocene epoch, about 56-50 million years ago.
Eurotherium is an extinct paraphyletic genus of placental mammals from extinct family Hyaenodontidae that lived from the early to middle Eocene in Europe.
Nanotitanops is an extinct genus of Brontothere from the middle Eocene of China. It contains a single species, N. shanghuangensis. It is known only from isolated teeth, the smallest of any known Brontothere.
