This arboreal #FossilFriday is Megaladapis edwardsi, an extinct giant lemur which lived about 5,000 years ago. Primates, such as Megaladapis, probably originated as tree-dwelling animals, and most of them still spend at least part of their time there. Among primates, we humans are unusual in living entirely on the ground. Primates and their closest relatives, the bats, have flexible ankles, built for climbing trees.
