This dentition suits the omnivorous diet of most modern procyonids. However, the diet of the giant panda, Ailuro-poda melanoleura, consists almost exclusively of bamboo shoots, and it is probable that this animal is more closely related to the bears than to the raccoons.
name: Plesictis time: Early Oligocene to Early
Miocene locality: Asia (China), Europe (France) and North America (USA) size: 2 ft 5 in/75 cm long This tree-living hunter had big eyes, perhaps for nocturnal hunting, and a long tail for balance. It was similar to the modern cacomistle (Bassaricus sumich-rasti), and may have been its direct ancestor. It probably led the same life-
