Docodon (meaning 'beam tooth') was an omnivorous mammal from the middle to upper Jurassic Period that lived in Europe and North America approximately 175.6 to 144 million years ago. Docodon likely inhabited woodland and stayed in trees out of the reach of predators. Weather Docodon was a true mammal is under debate, and some suggest it was an evolved therapsid or mammal like reptile.
