Two US paleontologists have discovered that the dinosaurs whose fossil remains were found in 1942 actually belong to dwarf tyrants and not to young tyrannosaurs
The Tyrannosaurus rex continues to be talked about following the analyzes of fossil remains carried out by Nicholas R. Longrich of the University of Bath and Evan T. Saitta of the University of Chicago. The two American paleontologists conducted a study published in Fossil Studies in which a new truth about dinosaurs. The tracks found in Montana in 1942 belong to adults of the species Nanotyrannus lancensis (dwarf tyrants) and not to young T.rexes. The theory that the fossils were from young tyrannosaurs has been called into question through the number of bone growth rings.
If you look at the juveniles of other tyrannosauroids, they display many of the defining characteristics of adults. A very young Tarbosaurus, for example, shows the typical characteristics of adults, even if they are smaller in size. Nanotyrannus, however, looks nothing like an adult T. rex and grew in a completely different way than any other tyrannosauroid.
Research on dinosaurs and their fossils has also used another method
The two paleontologists also used another research method via the frontal bone of a young man tyrannosaurus of the San Francisco museum. This specimen had a skull approximately 45 cm long and a body approximately 5 meters long. In this regard, paleontologist Nicholas R. Longrich of the University of Bath stated:
Yes, it’s just one specimen and just one bone, but that’s enough to confirm that Nanotyrannus is not a juvenile T.rex. The skull bones of this animal are very particular and although fossils of young individuals are incredibly rare, this does not mean that they have not already been discovered.
The authors of the study intend to continue research on dinosaurs and their fossil remains to further demonstrate the validity of their analyses.
