In Depth
Protypotherium might have looked like a long legged rabbit, but it was actually a notoungulate, a group of mammals unrelated to rabbits. The biggest confusion about Protypotherium is regarding its diet since it possesses all forty-four mammalian teeth, yet no real specialisation towards a specific diet. While Protypotherium is usually interpreted as being a browser of vegetation, there is commonplace speculation about how it might have been a scavenger of carrion as well.
