Google is a wasteland of crap for the usual reasons plus sites are full of rank speculation for SEO even though only a skull and some teeth were found. The Wikipedia page is a horrible read. Edited for readability.
Andrewsarchus is an extinct genus of ungulate that lived during the Middle Eocene in China. That's 47.8 and 41.2 million years ago. Only known from a largely complete skull as well as isolated teeth, It is notable for being estimated as the largest terrestrial, carnivorous mammal, but that status has been disputed. Andrewsarchus mongoliensis was named by Henry Fairfield Osborn in 1924 for a partial skull from the Irdin Manha Formation of Inner Mongolia. The genus was named in honor of Roy Chapman Andrews, the leader of the expedition on which it was discovered, with the Ancient Greek archos added to his surname.
