We find fossils today more than ever. Even this year is a very important year for fossils because we have already described 46 new species of dinosaurs only this year.

their beginnings were very humble they were very small the first dinosaurs that we know from the fossil records that are about 230 to 235 million years old they were tiny by comparison they were about the size of a cat or maybe the size of a dog and only later they became increasingly large and at the very beginning they were still competing against the crocodile ancestors and against synapsids which are the mammal ancestors and only

after a large mass extinction at the end of the Triassic period, about 200 million years ago, they out-competed all the other species and then became the rulers. And by that, I mean they conquered all... territory or terrestrial land. We find dinosaurs in the fossil record from all continents, even Antarctica or Australia.

They have conquered regions that were inaccessible for other animals because they had an elevated metabolic rate, so they were more active. They could run fast.

and also most of them at the beginning were bipedal and they carried their arms and legs under their body so they had straight arms and straight legs which made it easier for them to run and also the arms did not press against the lungs so they could breathe easily

While lizards, for example, they cannot run and breathe at the same time, so they have to hold their breath for a little while and then they run very fast, but then they have to catch their breath and only then they can continue to run. But dinosaurs like mammals today could run continuously.

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.
