dinosaur

Ancient Greek δεινός (deinós, "terrible, wonderful, mighty, terrible awesome") + σαῦρος (saûros, "lizard, reptilian") was created by paleontologist Richard Owen in 1842

Animals belonging to dinosaur branches, especially animals that existed during the Triassic, Jurassic and Cretaceous, are now extinct. [c from 1840]

(Prohibited) Dinosaurs are extinct reptiles. It existed between 230 million and 65 million years ago.

Many animals, often referred to as dinosaurs, are not dinosaurs, they are not real dinosaurs. These include pterosaurs, fish dragons, and paleontology. Dinosaurs are unpopular in scientific writing but still exist in media and everyday speech so please explain these.

On the contrary, not all the dinosaurs have been extinct in the Cretaceous-Quaternary extinction. Because survival is the ancestor of modern birds, they also belong to dinosaurs. However, except for some popular scientific books, birds are not usually described as dinosaurs.

When asked to an ordinary paleontologist familiar with vertebrate phylogeny, it may be said that the bird is a dinosaur. With appropriate terms, birds are dinosaurs of birds, other dinosaurs are dinosaurs other than birds, and birds (sounds strange) are technically considered reptiles. Is it too technical? Only semantics? Perhaps, still a good science. In fact, the majority of evidence supports birds as descendants of Manilaprán dinosaurs, which are similar (but not identical) to small dromosaurs. What is this evidence?

Given that: dinosaurs are the birds' ancestors. Assumption: As birds are endothermic, dinosaurs must be endothermic. Question: Yes, it must be correct at some point during the evolution of the bird. Where is the problem? Only one dinosaur is the ancestor of all birds and I do not know which is certain (though it is thought that Archeoptery is closely related). When a change in endotherm occurs before the bird's origin, other dinosaurs do not absorb heat. If it happened sooner, where is the evidence? Where do you draw the border between the sun's hot dinosaur and the endothermic ancestors? As a confusing question, there are definitely some of the most convincing evidence of non-bird dinosaurs that may be at risk

Birds may listen to people saying they are related to dinosaurs, but that is not true - birds are irrelevant to dinosaurs ... they are dinosaurs! In addition to the dinosaur group 65 million years ago, huge extinction eliminated all dinosaur groups - this dinosaur group is all the birds we are seeing today as well. But let's start from the beginning. Dinosaurs are diverse animals that first appeared before 344,340. Until there is almost no extinction they are dominant living beings in 135 million years of land. Although the cause of extinction is still a matter of discussion, the most likely choice seems to be the influence of asteroids (although volcanic eruptions are very likely).
