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 fed 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 Tillodontia, 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, Cenozoic Era. The only fossils that have been recovered are from the Willwood Formation, 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, 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 ...
