Unfortunately, these elements dont exist in dinosaur fossils themselves. Each of them typically exists in igneous rock, or rock made from cooled magma. By using radiometric dating to determine the age of igneous brackets, researchers can accurately determine the age of the sedimentary layers between them.

How accurate are dinosaur models?

Palaeoart images of dinosaurs are only ever as accurate as the fossil evidence available. Despite the anatomical errors and other inaccuracies, Parkers illustrations are so beautiful and detailed that they remain favourites among dinosaur fans and experts alike.

Can at Rex eat a human?

rex surely would have been able to eat people. There are fossil bite marks, matching the teeth of T. rex, on the bones of Triceratops and duck-billed dinosaurs such as Edmontosaurus, which were both over 50 times heavier than an average person. But that doesnt mean we would be hunted to extinction.
