The Deinonychus were less than three feet long from head to tail, but their emerald plumage made them seem larger. Long wispy feathers sprouted from their heads and ran in a row down their backs.
The two-legged dinosaurs fled in all directions, screeching and hissing. Their mouths were filled with more than sixty sharp points, lined up like the teeth on a saw.
“They look like birds,” Callie observed.
“Yeah, birds with arms and hands instead of wings,” Tim said. “They’re acting more like a pack of dogs, though. Coyotes maybe.”
