Why do scientist think dinosaurs are reptiles?
The main possibilities are that: Dinosaurs were cold-blooded, like modern reptiles, except that the large size of many would have stabilized their body temperatures. They were warm-blooded, more like modern mammals or birds than modern reptiles.
What characteristics do modern birds have that dinosaurs do not?
Not only are birds much smaller than their dinosaur ancestors, they closely resemble dinosaur embryos. Adaptations such as these may have paved the way for modern birds’ distinguishing features, namely their ability to fly and their remarkably agile beaks.
What did birds and dinosaurs have in common?
Birds have scales like many dinosaurs and some dinosaurs may have had feathers. This suggests that there is a common ancestor between dinosaurs, birds, and reptiles. Furthermore, birds have scales on their feet!

What if dinosaurs were still alive?
Some cryptozoologists think there could be many prehistoric animals still around today, even though modern science tells us they are extinct. But if dinosaurs are still alive, that would be another class of amazing altogether!
Do dinosaurs still lurk in the wild?
There are no photographs or films of the creature, no bones or teeth, no evidence beyond stories and anecdote. Of course the fatal flaw in the idea that giant dinosaurs still lurk in remote jungles or cold, deep lakes is that all the evidence suggests they died out about 65 million years ago.
Well, birds are actually descendants of the carnivorous dinosaurs like Tyrannosaurus Rex and velociraptors. Therefore, by the “all descendants” clause, birds are also part of the group Dinosauria.

What are the modern day descendants of dinosaurs?
Modern-Day Dinosaurs: The Descendants Of Dinosaurs That Surround Us Today. Birds are actually descendants of the carnivorous dinosaurs like Tyrannosaurus Rex and velociraptors. Therefore, by the “all descendants” clause, birds are also part of the group Dinosauria, and in effect, are a kind of dinosaurs.
