Scientists used to believe that dinosaurs were cold blooded, like modern reptiles. However, the fact that birds clearly evolved from dinosaurs and the fact that birds are warm blooded put that belief into question. Examination of the growth rings in dinosaur bones shows a steady growth rate, which is indicative of warm bloodedness.
What else can I help you with?
Are dinosaurs warm blooded animals or cold blooded animals?
Dinosaurs are a group of reptiles, therefore they are cold-blooded.
Are dinosaurs warm blooded animals or cold blooded?
Dinosaurs are a group of reptiles, therefore they are cold-blooded.
Invertebrates are warm and cool blooded animals?
dinosaurs are the animals which are warm blooded.
Do dinosaurs have could or warm bould?
It is unknown whether dinosaurs were warm or cold blooded. Evidence suggests the former, because some lived in cold climates year round, they grew at a similar rate to warm blooded animals, and their descendants, birds, are warm blooded.
Were dinosaurs cold blooded?
they are believed to be related to birds according to evolution. Dinosaurs were considered luke-warm blooded because they could survive in the cold and the warm. Though another theory is the evolution with birds, I think this is a good answer.
What are dinosaurs warmblooded vertebrates called?
No, they were not. There were many other warm blooded species before them. I'm not sure of specific names, but I know that birds were along much longer than the dinosaurs, and birds are warm blooded. Let me clarify from above. According to the currently accepted Evolution Theory, birds evolved from dinosaurs. Birds are warm blooded but dinosaurs, as far as the scientists can tell, were cold blooded.
What dinosaur is cold blooded vertebrate that usually lays eggs?
All dinosaurs, including birds, which are considered a group within the clade Dinosauria, laid eggs.It is unknown whether dinosaurs were warm blooded or cold blooded. Possibilities include:All dinosaurs were warm blooded, and none were cold bloodedAll dinosaurs were "lukewarm" blooded, meaning they had some control over their body temperatures, but not as much as modern warm blooded animals, like mammals or birds.All dinosaurs were cold blooded.Some types of dinosaurs were warm blooded while others were lukewarm or cold blooded.The growth rate of dinosaurs as revealed by their fossilized bones and the fact that their anatomies suggest very active lifestyles, which cold blooded animals would not be able to maintain, among other pieces of evidence, strongly suggest that at least theropods were warm blooded, if not all dinosaurs. Theropods were three toed, bipedal dinosaurs, most of which ate meat. Examples includes T-rex, Velociraptor, Allosaurus, Troodon, and Ornithomimus.In other words, it appears most likely that all dinosaurs laid eggs, but they were warm blooded.
Were there any warm blooded dinosaurs?
All Dinosaurs where Warm-Blooded. It has been discovered because they are mostly predetors and would be hunting continuously, so it would be venerable if it was recharging in the sun if it was a cold-blooded herbivore and would be venerable. So paleontologists think Dinosaurs where Warm-blooded.
was the stegosaurus warm or cold-blooded?
Stegosaurus was a dinosaur, and paleontologists continue to find more evidence that dinosaurs were warm blooded. Thus, Stegosaurus was probably warm blooded.
Is dinosaurs warm-blooded?
There are a number of arguments for dinosaurs being warm blooded, cold blooded, or somewhere in between. Their growth rate, and evidence of high levels of activity, as well as the fact that Leallynosaura has adaptations for the Antarctic winter other than hibernation, suggest that they were warm blooded.
How would the dropping tempuratures impact the dinosaurs?
Well because the dinosaurs were adapted to warm weather and they were cold blooded.
Is a T Rex warmblooded or cold blooded?
Apatosaurus was a dinosaur, and relatively recent research suggests that dinosaurs were in fact warm blooded. Sauropods such as Apatosaurus appear to also have been warm blooded.
