This specimen is a very beautiful museum quality footprint, possibly that of Albertosaurus. It shows all the features common to the family of Tyrannosauridae. Albertosaurus was a smaller dinosaur than was Tyrannosaurus rex, but still had the same features of short, puny arms, a massively built short body, a big head and pillar-like legs to support its great weight. This monster weighed over three tons.

This particular specimen is smaller in size than are most of the tyrannosaurid forms of therapod dinosaurs. This specimen is possibly a juvenile form of Albertosaurus that roamed the Blackhawk Formation coal swamps of the Late Cretaceous Period of the Mesozoic Era. This footprint represents a beautiful museum specimen. This animal was eight meters long.

This footprint is unique because of the claw marks shown at the tip of each digit. This tyrannosaurid, possibly belonging to the albertosaurs, was a smaller dinosaur than the Tyrannosaurus, but shows many of their common features. This one had a massively built head and short body with pillar-like legs to support its great body weight. It has been suggested that the Albertosaurus tiny arms were used by the males to hold onto the females while mating.

A very beautiful museum specimen, this therapod dinosaur footprint was extracted from the ancient coal swamps of 65 million years ago. This specimen represents very possibly an albertosaur species of the Tyrannosauridae family. Their arms were puny in comparison to their body size. The small tyrannosaur shows all the features common to the family.
