An article published in the journal “Scientific Reports” describes a research on the bite force of Tyrannosaurus rex. Researchers Gregory Erickson and Paul Gignac created computer models based not only on fossils but also on the study of dinosaurs’ living relatives, crocodiles and birds, to estimate T.rex’s bite characteristics concluding that it could crush its prey’s bones.
An article published in the journal “Scientific Reports” describes the discovery of a new tyrannosaurid, a group of carnivorous theropod dinosaurs that included the famous T. rex. Called Daspletosaurus horneri, it was discovered in Montana and has an age of about 75 million years. The fossils’ excellent state of preservation allowed an analysis that suggests that it had sense organs on its snout similar to those of crocodiles and was a descendant of Daspletosaurus torosus.
An article published in the journal “Current Biology” describes a research on a dinosaur belonging to the genus Psittacosaurus that lived in modern China at the beginning of the Cretaceous period, about 120 million years ago. A team from the University of Bristol examined the skin remains of a very well preserved specimen cataloged as SMF R 4970 concluding that its coloration provided it some camouflage.
