Tillodontia
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 feed on roots and tubers in temperate to subtropical habitats. Description Tillodonts had rodent-like incisors, clawed feet and blunt, cusped teeth. They were mostly medium-sized animals, although the largest of them (such as ''Trogosus)'' could reach the size of a large bear. The cranium ranged in length from and had a characteristic elongated rostrum, an elongated mandibular symphysis, and a shortened basicranial region. The second upper and lower incisors are large in most species, the first upper and lower premolars are small or absent, the fo ...

Azygonyx
''Azygonyx'' was a small tillodont mammal, likely the size of a cat to raccoon, that lived in North America during the Paleocene and Eocene in the early part of the Cenozoic Era. The only fossils that have been recovered are from the Willwood and Fort Union Formations in the Bighorn Basin of Wyoming, United States, and date to the Clarkforkian to Wasatchian, about 56 to 50 million years ago. Fifty-six collections that have been recovered thus far include the remains of ''Azygonyx''. ''Azygonyx'' survived the Paleocene Eocene Thermal Maximum along with other mammals like ''Phenacodus'' and ''Ectocion'', both of which were ground-dwelling mammals. ''Azygonyx'' probably was a generalist terrestrial mammal that may have roamed around the ground, but was also capable of climbing trees. Etymology The genus name comes from the "''a''-" meaning absent, "''zygos''-" meaning joining, and "''onyx''" meaning claw referencing the unjoined claw-like incisors. Taxonomy ''Azygonyx'' is plac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meiostylodon
''Meiostylodon'' is an extinct genus of tillodont that lived during Paleocene. The lone type species, ''M. zaoshiensis'', is known only from three isolated teeth found at Zaoshi, Chaling County, Hunan Province in the People's Republic of China.B.-Y. Wang. 1975.

''Vertebrata PalAsiatica'' 13(3):154-162 These isolated fossil teeth are stored at the Paleozoological Museum of China The Paleozoological Museum of China (PMC; ) is a museum in Beijing, China.

Trogosus
''Trogosus'' is an extinct genus of tillodont mammal. Fossils have been found in Wyoming, California, and British Columbia, and date from the Eocene between 54.8 and 33.7 million years ago. ''Trogosus'' was a bear-like herbivore with a large, short skull and flat feet, and had a skull long with an estimated body weight of . It had large, rodent-like incisors, which continued growing throughout the creature's life. Judging from the heavily worn molar teeth The molars or molar teeth are large, flat teeth at the back of the mouth. They are more developed in mammals. They are used primarily to grind food during chewing. The name ''molar'' derives from Latin, ''molaris dens'', meaning "millstone to ..., ''Trogosus'' fed on rough plant material, such as roots and tubers.
