Palaeochiropteryx tupaiodon is the most common mammal found at Messel. An additional species of Palaeochiropteryx, P. sambuceus, has been described from the middle Eocene of North America. [4] All other species belonging to Palaeochiropterygidae are known only from isolated teeth and jaw fragments from Europe, India, Turkey, and possibly North ...
