The discovery of Anzu, which is named in part for a feathered demon from Mesopotamian mythology, provides detailed evidence of oviraptorosaurs in North America. (Most of these creatures have been found in Asia.) It also suggests that even until the end of their reign certain communities of dinosaurs were evolving and flourishing. This is contrary to earlier assumptions that dinosaurs were on the decline just before the astroid strike due to climate change.
