Mesonychidae (meaning "middle claws") is an extinct family of small to large-sized omnivorous-carnivorous mammals.They were endemic to North America and Eurasia during the Early Paleocene to the Early Oligocene, and were the earliest group of large carnivorous mammals in Asia.
Ungulates were in high diversity in response to sexual selection and ecological events; most ungulates lack a collar bone. [49] Terrestrial ungulates were for the most part herbivores, with some of them being grazers. However, there were exceptions to this as pigs, peccaries, hippos and duikers were known to have an omnivorous diet.
Mesonychia ("middle claws") is an extinct taxon of small- to large-sized carnivorous ungulates related to artiodactyls. Mesonychians first appeared in the early Paleocene, went into a sharp decline at the end of the Eocene, and died out entirely when the last genus, Mongolestes, became extinct in the early Oligocene. In Asia, the record of ...
In 2014, physician Pedro Lucas Porcela Aurelio found the fossil in the town of Paraiso do Sul in Brazil's southernmost Rio Grande do Sul state. He donated it to a local university in 2021, kicking ...
A nearly complete skull fossil found in Egypt has revealed a new species of Hyaenodonta, an apex carnivore that mysteriously went extinct about 25 million years ago.
Their unusually shaped feet are quite similar to that of ungulates, and fossil evidence suggests that there once existed a larger diversity of elephant species whose body structure puts them in ...
Andrewsarchus (/ ˌ æ n d r uː ˈ s ɑːr k ə s /), meaning "Andrews' ruler", is an extinct genus of artiodactyl that lived during the Middle Eocene in what is now China. The genus was first described by Henry Fairfield Osborn in 1924 with the type species A. mongoliensis based on a largely complete cranium.
Fossils of the reptile were first found in China in 1972. But researchers have struggled to understand the animal’s feeding behavior and lifestyle because none of the skulls were well preserved.
