A Bit More on Tree Dwellers

Tree dwellers are capable of using simple tools. They will get at the meat of hard-shelled fruits by holding the fruit in their rear paws like a vise and cracking the shell with a rock. They've also been seen using sticks to swat at misbehaving pups.

On a somewhat related note, while I've detailed the two members of the genus Vulpithecus, there are likely higher taxa of vulpithicids and vulpithecoids with extant members. They may be more vulpes than pithecus or more pithecus than vulpes.
