Are dinosaurs still alive today?
Today, paleontologists have made a pretty much open-and-shut case that dinosaurs never really went extinct at all; they merely evolved into birds, which are sometimes referred to as “living dinosaurs.” … Granted, Phorusrhacos went extinct millions of years ago; there are no dinosaur-sized birds alive today.
