== Description == left|thumb|Skeletal reconstruction This animal, of the size similar to that of today's American Mink (it was about 40 centimeters long excluding the tail), was equipped with a rather unusual morphology if related to that of its closest relatives. Contrary to shapes like Protypotherium, Interatherium possessed short and robust legs, and a long body and similar to that of a weasel. The front legs were equipped with four fingers. The ointment phalanges were compressed laterally, and some of these were divided.
