Independent speed calculations suggest that a reasonable cruising speed for Tyrannosaurus rex was 50 km (30 miles) per hour. Experts can count the number of rings to determine its age, as well as compare the spaces between rings to find out how fast the dinosaur was growing at different ages.

There are four basic pieces of evidence that lead the "yes" group of T. rex researchers to their conclusions. No, but we can look at various factors of things and make an educated guess. For instance, we know by looking at the general structure of Tyrannosa An interesting fact about the Brontosaurus was that it stood approximately 15 feet high at the hips, and had a length of about 90 feet. "Instead, they had growth rates and metabolisms intermediate to warm-blooded and cold-blooded organisms of today. The earliest known mammals were the morganucodontids, tiny shrew-size creatures that lived in the shadows of the dinosaurs 210 million years ago.
