Are Any Dinosaurs Still Alive Today?

Yes. In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other nonavian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.

Many, shared, evolutionary characteristics can be found in the skeletons of birds and other dinosaurs. One can follow the development of these evolutionary innovations by following along the evolutionary tree of dinosaurs from larger groups into successively smaller ones.
Birds' hips have a hole in the hip socket, just like all other dinosaurs. This feature was inherited from the common ancestor of dinosaurs and allowed dinosaurs to walk with an upright posture. Next, the bones of birds are hollow, and the hind feet of birds have three toes that point forward and one toe that points backwards, just like the hollow bones and three-toed feet inherited from the common ancestor of all meat-eating or theropod dinosaurs, including Tyrannosaurus.

Finally, the wrist of birds is built around a crescent-shaped bone called the semi-lunate carpal, just as the wrist of Velociraptor is. This wrist bone was inherited from the common ancestor of birds, Velociraptor, and other dinosaurs that belong to the group called maniraptors. As documented by these characteristics, birds evolved from the first dinosaur, the first theropod dinosaur, and the first maniraptor. So scientifically, birds are members of all of these groups of dinosaurs.

So, in an evolutionary sense, birds are a living group of dinosaurs, and although no nonavian dinosaurs, such as Tyrannosaurus or Triceratops, still exist, dinosaurs are not extinct! You see dinosaurs flying around in the sky and perching in trees every day!

believe there still roaming the earth to this day when i was about 10 i lived near a quarry and in the distince i could see a "raptor" type formed creature i didn't relize what it was because the passanger pigeon "was" extinct but there still living i beleive there still here !

There are millions of dinosaurs flying every day. Some are even served as dinner every day.

[paulfortune]

Ahem... velociraptor had feathers, could glide, likely climb trees, and has a very similar skeleton to a hawk or eagle.

[pussyianity]

Talking about dinosaurs that still exist to this day ??




Cough cough "crocodile" cough cough .

[hackersavageitsmoosemil]

I saw 1 before when I was 9 I got scared to grap it

[latiuwu]

Thay are alive this video was posted 5 years ago we still have proof thay hide some were idk but thay are alive

[aneurysm.]

Ark fans: allow us to introduce ourselves.

[chadhullraidenstrife]

I'll take real evidence over words any day

[colourmegone]

My understanding of the word species is that we are no far from primates at all, we ARE primates.

[Lynx]

Well pretty sure that sea dinosaurs still exist

[abhiv-sri]

I think that we see tiger, elephant etc animals are alive what happened the when these all animals are died when Dino saur are died and the dinosaur were alive than we call dinosaur as animals and animals as dinosaur.

[PeppoMusic]

Are the distinctions made between dinosaur and non-dinosaur not kind of arbitrary? Since modern day birds also posses plenty of characteristics that aren't very dinosaur-like. Also, what about some of our reptiles like crocodiles? With evolution being a gradual process and our fossil record only being a small account of all species ever lived, where do you draw the line? Wouldn't 'descendant' be more accurate? Since birds are farther from your average theropod than we are from primates.

[PeppoMusic]

Oh yeah, thanks for correcting me, forgot about that. But that makes his comparison to primates even more problematic in my opinion.

[clonecommanderrex]

the plant eating dino could have evolved to lizard and other reptiles

[verbenaphibikharkongor]

Are there any dinosaurs in real caught by YOUTUBERS ?

[jonathanwaugh]

Please show me the proof that evolution is real. Its a totally unproven theory
