There were more. In the Permian, Triassic, and early Jurassic periods there were mammal-like reptiles from which true mammals evolved, some of which were likely warm blooded.
Crocodiles and other reptiles are not dinosaurs. The family of reptiles separated from the animals that became dinosaurs several hundred million years ago and existed from that time, through the age of dinosaurs to the present. Dinosaurs evolved becoming warm blooded and to some extent covered with feathers. Reptiles remained cold blooded and scaly. The only living descendants of dinosaurs today are the birds.Crocodiles are, however more closely related to dinosaurs (and birds) than they are to most other reptiles, being members of the Archosauria.
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. Birds on the other hand are the only type of warm blooded, fuzzy reptiles alive today.Crocodilians are dinosaurs and birds closest living relatives.
It is not certain, as we have only fossilized bones which tell us little about dinosaurs' soft tissues and organs which we would need to determine warm-/cold-bloodedness, but generally assumed that dinosaurs were, like modern reptiles, cold-blooded. However, it has been recently discovered that at least some dinosaurs had live births, which is very surprising because it is most definitely not a trait of modern reptiles (modern reptiles lay eggs that hatch and do not have live births); this may lead to increased doubt over whether dinosaurs had many traits in common with modern reptiles, including being cold-blooded. Two groups of warm-blooded animals, mammals and birds, are descended from dinosaurs.
German Shepherds are dogs, dogs are mammals. Only fish and reptiles are cold blooded.
No, because dinosaurs did not have hooves.
Not only that dinosaurs are directly descended from reptiles and, under current taxonomy, are classified as reptiles.
Reptiles don't produce milk but mammals do. Its only because reptiles are cold blooded and mammals are warm blooded!
Not really,reptiles are solitary creatures, the only reptiles that I know of that travel together are dinosaurs
Only mammals have sweat glands. Dinosaurs were reptiles, so they did not have sweat glands.
Cold-blooded - just like all reptiles.
Dinosaurs are reptiles, so they breathe O2. Only plants breathe CO2.
no, only mammals and birds are warm blooded. reptiles, amphibians, insects etc. are cold blooded, like fish.
