In Jurassic Park 1 why does dr grant think dinosaurs have more in common with birds than with reptiles?
In "Jurassic Park," Dr. Alan Grant believes that dinosaurs share more characteristics with birds than with reptiles due to evidence of feathers and other avian traits found in some dinosaur fossils. He points to similarities in skeletal structure, nesting behaviors, and certain physiological traits that suggest a closer evolutionary relationship. Additionally, advancements in Paleontology and the study of modern birds support the idea that birds are the descendants of theropod dinosaurs. This perspective challenges the traditional view of dinosaurs as merely large, cold-blooded reptiles.
What else can I help you with?
Were the dinosaurs in Jurassic Park depicted accurately?
No, sadly they were not. We now know that dinosaurs (most of them) had feathers, like the Velociraptor. We found out because many feathers were found in amber from 75 to 80 million years ago during the Cretaceous era, with evidence that they were from both dinosaurs and birds.

What dinosaur is a reptile?
Yes, Dinosaurs were reptiles. Did you know Dinosaurs closest living relatives may be birds?EDIT: Birds ARE dinosaurs and therefore Birds are also reptiles!When most people think of reptiles they think of cold blooded, scaly, sprawling lizards and crocodiles.

Yes, dinosaurs did evolve from reptiles. They are part of a group called archosaurs, which also includes modern birds and crocodiles. Dinosaurs evolved from a group of reptiles called archosauriforms during the Triassic period.
What year did dinosaurs evolve from reptiles?
Evolution is generally a gradual process, such that it is generally difficult to classify transition species one way or the other. Would you say birds are reptiles? Birds are dinosaurs. Dinosaurs and reptiles share a common ancestor, probably dating to some time in the early Triassic. That would be around 250 million years ago.
