Experts have shown what the cubs of carnivorous dinosaurs that lived on Earth 70 million years ago looked like.
Paleontologists at the University of Edinburgh have published the results of a study of the fossilised remains of a jaw bone and claw of a Tyrannosaurus rex cub found in Canada.
The remains belonged to a small tyrannosaurus – cousin of the legendary T-Rex.
According to 3D scanning data, the tyrannosaurus baby hatched from the egg was about 90 cm in length, and in adulthood reached 12 meters.
