I just wanted to post this interesting information somewhere and decided to post it under the photo of this cold-blooded reptile: I know most people think that dinosaurs were more related to reptiles – like snakes – than to birds, but in fact they were not at all. They may have the same ancestry, but most reptiles developed at the same time as dinosaurs, while birds descent from two-legged dinosaurs. I already knew that. Still I was surprised when I saw the documentary movies “The Real Jurassic Park” and “Prehistoric Park Episode 4 and 5” in which they stated that dinosaurs and birds had more in common than dinosaurs and reptiles. Like birds and unlike reptiles they were warm-blooded – or at least that would be the only explanation why they could dominate over mammals for millions of years -, they built nests made of twigs, fossils make us think that they cared for their chicks – of all reptiles only crocodiles care for their young ones, but only for a very short amount of time -, judging by fossils their chicks must have been protected by downy feathers, most grown-up two-legged dinosaurs must have had feathers too, the structure of their leggs resembled the feet of ratites, like ostriches or emus and their intelligence must have been comparable to some specimens of birds rather than crocodiles, turtles, tortoises or snakes. After all for example velociraptor hunted in a pack and many other two-legged dinosaurs also lived in herds, while there isn’t a single reptile that has something like a real family-life. Scientists also found out that dinosaur-eyes must have worked like bird-eyes; i.e. they must have seen colours, which draws people to the conclusion that baby-dinos must have considered the first living creature they saw as their mother, while most reptiles don’t recognize either of their parents and actually don’t even care about the siblings with which they hatch.
