Why did T Rex have small arms
The precise purpose of T.
rex’s relatively tiny arms has long been mysterious.
Over the years, scientists have suggested that they might have been used to grasp struggling prey, to help resting dinosaurs push themselves up from the ground, or to grip tight to mates during sex..
What a T rex actually looked like
rex with feathers, so we can infer it.” Scientists hypothesize that the skin of the T. rex wasn’t scaled, but more like the skin of a turtle. They also had footprints similar to their bird relatives.
Were dinosaurs warm blooded or cold blooded
The diagram above shows energy usage in a number of animal groups, including birds, mammals, dinosaurs and modern reptiles. Dinosaurs were “mesotherms,” neither warm- nor cold-blooded, a new study finds.
Did the T Rex have color vision
Sight: T. rex had an eye about the size of a softball, one of the largest eyes ever developed in the animal kingdom – past or present. This would have included plenty of space for black-and-white and color receptors; since its ancestors (crocs) and its descendants (birds) see in color, scientists think T. rex did, too.
Are dinosaurs still alive today
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
Are cats warm blooded
Dogs and cats are homeotherms, meaning they maintain a fairly constant body temperature of 101 to 102 degrees, according to James H.
Are there any cold blooded humans
Humans are warm-blooded, with our body temperature averaging around 37C. Warm-blooded simply means we can regulate our internal body temperature, independent of environment, while cold-blooded animals are subject to the temperature of their surroundings.
Do cold blooded animals feel pain
With regard to pain or suffering, there is no difference between warm-blooded and cold-blooded animals.
Are all dinosaurs cold blooded
Dinosaurs were cold-blooded, like modern reptiles, except that the large size of many would have stabilized their body temperatures. They were warm-blooded, more like modern mammals or birds than modern reptiles.
Could T rex have had feathers
Scientists now believe that all tyrannosaurs had feathers; while small species like Dilong would have been covered with them, the adult T. rex probably had just patches for display. The advantage T. rex had on its ancestors was its growth spurt.
Are humans warm blooded
Humans are warm blooded, meaning we can regulate our internal body temperature regardless of the environment.
Did any dinosaurs have feathers
Did dinosaurs have feathers? Yes! When the first perfectly preserved specimens of feathered dinosaurs were found in China in the 1990s, it was proved beyond doubt that these ancient animals were the ancestors of modern-day birds.
