What is "adinotherium"

Adinotherium (meaning "not terrible beast") is an extinct genus of Toxodontidae, large bodied hoofed ungulates which inhabited South America during the Miocene living from 17.5—11.61 Ma and existed for approximately . The long animal,with a 120 kg weight, looked like a smaller version of its rhinoceros-like relative Toxodon. Its front legs were somewhat longer than those of its relatives, making its hip and shoulder height about equal. A small horn atop Adinotherium's skull may have played a role in the mating season.
