The hyrax skeleton is remarkably similar to the protorohippus skeleton. Both have simple tapir-like teeth and four front toes and three rear toes. It's possible that some of these finds were in fact early hyrax which have been wrongly attributed to the protorohippus imo. Mystery three toed tracks have been found all over North America. Is there a clever species of modern hyrax which is able to stay undetected from science?
