So in nature, it's always better to be bigger because then you're less likely to become the source for other animals' food. And if you're big, then you're less likely to be hunted down, less likely to be killed, less likely to be eaten. And the dinosaurs had very special body shapes that enabled them to grow bigger than mammals today.

Yeah, so the largest of them all were the long-necked dinosaurs, and they could grow up to 100 feet in length, maybe even larger. Just because we find one that is about 100 feet long doesn't mean that that was the biggest. biggest specimen of this particular species. Chances are there might have been some specimens that were even larger and we just haven't found them yet.

But we know for sure that some of the long neck dinosaurs could grow up to about 100 feet long and maybe up to 100 tons in body mass. So that is quite enormous. And the largest predators like Tyrannosaurus, for example, they could grow up to 45 feet in length. and they could weigh as much as two elephants, African elephants.

The first dinosaurs, they started out as meat eaters and only later some of them became herbivorous. So they started eating plant matter. And that is true for the sauropods. No sauropod ever ate anything else but plants. So they were all vegetarians. But the so-called theropods to which Tyrannosaurs and Allosaurs belong, they were carnivorous. They were meat eaters.

yeah so that is a very good question and the short answer would be that in some cases we do actually find tissue we find skin impre skin impressions on rocks so we know that they had scales and some of the smaller theropods they actually had feathers and later on they they all become feathered like all the theropods the meat eaters and some of the um

herbivores they had so-called proto feathers so they look like hair but but um biologically they are more closely to feathers than hair but like the long neck dinosaurs a very big dinosaurs they had scales and tyrannosaurs they had scales so they didn't have feathers so we know that and then in some cases we actually can reconstruct uh the color but this is very limited to very few species

That is right. All dinosaurs share the same last common ancestor.

That is right. All dinosaurs share the same last common ancestor.

All birds are also. So birds are basically a very special kind of dinosaur. And they're the only surviving dinosaurs after the end Cretaceous mass extinction event when the asteroid struck Earth.
