Underneath the treetop canopy of a Late Cretaceous forest around 68 million years ago, an arboreal dromaeosaurid perches on a gnarled tree bough. In the background, the heads of two sauropods of the species Alamosaurus sanjuanensis poke up from the understory further below.

The raptor here is a fictional species of my own creation, though it would not surprise me if such a tree-dwelling dinosaur did turn up in the fossil record sooner or later.
