The "Continental Mesozoic" Exhibit at the Novosibirsk State University Scientific and Educational Center "Evolution of the Earth" has added a new feature. This new element is a life-size model of a Tyrannosaurus rex skull, the most famous predator of the Cretaceous period. The skull was created on a 3D printer as part of the "Priority - 2030" Program. The T-Rex skull is in a display case along with models of the Siberian Psittacosaurus (pterosaur and Velociraptor), skeletons, reconstructions of various dinosaur eggs, stone slabs with imprints of bony fish, and plant fragments.
Tyrannosaurus rex was the largest land predator in the history of our planet and the most massive among other tyrannosaurs. The length of the body from the tip of the nose to the tip of the tail reached 10-12 meters it’s weight was from 7 to 10 tons. The teeth of this giant predator grew throughout its life and changed as needed. If the T-Rex lost a tooth, a new one would soon grow in its place. This process can be seen by looking closely at the model.
Tyrannosaurus rex bones have not been found in Siberia as there are no layers here that correspond to the period when these giants walked the Earth. The nearest layers of this age have been discovered in the Far East and Chukotka. In the Far East, there are known finds of teeth that are similar to the teeth of tyrannosaurs, but these fossils have not yet been described in detail. It is known that their relatives, the tarbosaurus, lived in Mongolia. Another relative of the tyrannosaurs, the kilesk, was discovered in Siberia. So far, only parts of its skull have been found. However, it has been established that these creatures lived long before the T-Rex, approximately167-165 million years ago.
