A Very Big Carnivore
Though Andrewsarchus is known only from one specimen, "based on skull anatomy, we can figure out where it fits on the mammalian family tree, and based on its position in relation to its closest relatives, we can reconstruct its anatomy and body size," said Flynn.
The reconstructions show that Andrewsarchus was big, standing 6 feet tall at the shoulder and looking more than a little like an oversized, hyper-predatory giant boar. Its teeth were adapted to eating meet, said Flynn, making Andrewsarchus "probably the largest meat-eating land mammal that ever lived."
