Smilodectes is a genus of adapiform primate that originated during the Middle Eocene epoch in what is now North America.
Thought to have been extinct for 50 million years, there are still some that remain alive on Primeval Island. In fact, they are among the most common primate there, alongside Dinopithecus, Australopithecus, Homo Habilis, Paranthropus, Homo Rudolfensis, Ardipithecus, Pliopithecus and Gigantopithecus. They are also one of the smallest animals on the Island, alongside Archaeopteryx.
