Deinonychus Antirrhopus was a raptorian that terrorized any prey that dared to come into its sight, that included humans. After the devastating tower of babel event struck the Earth, people broke apart and spread all around the world, the humans that expanded to North america (killing anything in their path) most likely had trouble when they came across this creature; it had to have resulted in some casualties. There has only been one full Deinonychus skeleton, and the complete sample was uncovered in the year of 2021; fairly recent. The Deinonychus was a ferocious carnivore that preyed on humans, north american mammals, tenontosaurus, and zephyrosaurus. Evolution scientists state that the Deinonychus Antirrhopus was covered in feathers; they back this up because it was covered in quill points. They also found “feather” impressions that look nothing like feathers, but exactly like animal skin that has been decaying in water. So the deinonychus was covered in, not feathers, but quills.
