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.
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 ...
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 ...
Researchers have uncovered fossils of giant predator worms, some of Earth’s earliest carnivorous animals that roamed the seas 518 million years ago.
The observations of California ground squirrels engaging in "carnivorous behaviors" were all recorded this year. About 42% of the 74 interactions witnessed between June and July involved "active ...
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.
Scientists have revealed fossils of a giant salamanderlike beast with sharp fangs that ruled waters before the first dinosaurs arrived. The predator, which was larger than a person, likely used ...
