Robert Milton Schoch is an American associate professor of Natural Sciences at the College of General Studies, Boston University. Following initial work as a vertebrate paleontologist, Schoch co-authored and expanded the fringe Sphinx water erosion hypothesis since 1990, and is the author of several pseudohistorical and pseudoscientific books.
Cimolesta is an extinct order of non-placental eutherian mammals. Cimolestans had a wide variety of body shapes, dentition and lifestyles, though the majority of them were small to medium-sized general mammals that bore superficial resemblances to rodents, lagomorphs, mustelids, and marsupials.
Taeniodonta is an extinct order of eutherian mammals, that lived in North America and Europe from the late Cretaceous (Maastrichtian) to middle Eocene.
Stylinodontidae is an extinct family of mammals from extinct superfamily Stylinodontoidea within extinct order Taeniodonta, that lived in North America from the early Paleocene to middle Eocene.
Dinocerata or Uintatheria, also known as uintatheres, is an extinct order of large herbivorous hoofed mammals with horns and protuberant canine teeth, known from the Paleocene and Eocene of Asia and North America. With body masses ranging up to 4,500 kilograms (9,900 lb) they represent some of the earliest known large mammals.
Oodectes is an extinct paraphyletic genus of placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene.
Meniscotherium is an extinct genus of dog-sized mammal which lived 54–38 million years ago. It was a herbivore and had hooves. Fossils have been found in Utah, New Mexico. and Colorado. Many individuals have been found together, indicating that it lived in groups.
Psittacotherium is an extinct genus of taeniodonts from extinct tribe Psittacotheriini within subfamily Stylinodontinae and family Stylinodontidae, that lived in North America from early to late Paleocene. With a weight between 35.6 kg (78 lb) and 71.2 kg (157 lb), and length of 1.125 m, it had similar size of a large dog.
Tillodontia is an extinct suborder of eutherian mammals known from the Early Paleocene to Late Eocene of China, the Late Paleocene to Middle Eocene of North America where they display their maximum species diversity, the Middle Eocene of Pakistan, and the Early Eocene of Europe. Leaving no descendants, they are most closely related to the pantodonts, another extinct group. The tillodonts were medium- to large-sized animals that probably fed on roots and tubers in temperate to subtropical habitats.
The San Jose Formation is an Early Eocene geologic formation in the San Juan Basin of New Mexico and Colorado.
Schowalteria is a genus of extinct mammal from the Cretaceous of Canada. It is the earliest known representative of order Taeniodonta, a specialised lineage of eutherian mammals otherwise found in Paleocene and Eocene deposits. It is notable for its large size, being among the largest of Mesozoic mammals, as well as its speciation towards herbivory, which in some respects exceeds that of its later relatives.
Viverravus is an extinct genus of placental mammals from extinct subfamily Viverravinae within extinct family Viverravidae, that lived in North America, Europe and Asia from the middle Paleocene to middle Eocene.
Protictis is an extinct paraphyletic genus of placental mammals from extinct subfamily Didymictinae within extinct family Viverravidae, that lived in North America from early Paleocene to middle Eocene.
Ectoganus is an extinct genus of taeniodonts from tribe Ectoganini within subfamily Stylinodontinae and family Stylinodontidae, that lived in North America from late Paleocene to early Eocene.
Hemipsalodon is an extinct genus of hyainailourid hyaenodonts from the subfamily Hyainailourinae that lived in North America during the middle to late Eocene.
Conoryctella is an extinct genus of taeniodonts from extinct tribe Conoryctellini within extinct subfamily Conoryctinae and extinct family Conoryctidae, that lived in North America during the early Paleocene.
Conoryctidae is an extinct family of mammals from extinct order Taeniodonta, that lived in North America and Europe from the early Paleocene to early Eocene.
Stylinodontinae is an extinct subfamily of mammals from extinct family Stylinodontidae, that lived in North America from the early Paleocene to middle Eocene.
Conoryctinae is an extinct subfamily of taeniodonts from extinct family Conoryctidae, that lived in North America from the early to middle Paleocene.
Wortmania is an extinct genus of taeniodonts from extinct subfamily Wortmaniinae within extinct family Stylinodontidae, that lived in North America during the early Paleocene.
