New details about T. Rex found
New details about teenage Tyrannosaurus rex dinosaurs were brought to light, scientists say. Fossilized skeleton samples of T. rex found in Montana, USA were inspected by a crew of researchers. The two dinosaurs named Jane and Petey by the researchers were proved to be twice as long as a horse and were slightly taller than a horse.

Fossilized skeleton samples aided the researchers in charge to comprehend the history and development of the ancient animals on a deeper level. They detached thin parts from the leg bones of the two dinosaurs. Then, they studied the bone pieces under a microscope. The experts explained that examining the microstructure of the fossils provides significant information about the growth rate, age, and metabolism of the creature.

Based on their findings, young T. rex dinosaurs would move around swiftly and had teeth similar to a knife, while a fully-grown counterpart had teeth that could squash huge bones. In addition, an adult T. rex can grow up to 12 meters long and 5 meters tall.
