Des paléontologues ont mis au jour le crâne de stégosaure le mieux conservé jamais découvert en Europe sur un site à Riodeva, en Espagne. Le fossile appartient à un Dacentrurus armatus et remonte à la période du Jurassique supérieur, il y a environ 150 millions d'années.

Des chercheurs de la Fundación Conjunto Paleontológico de Teruel-Dinópolis ont identifié le spécimen lors de fouilles sur le site d'Están de Colón, dans la formation de Villar del Arzobispo. Le crâne offre des détails anatomiques rares, car de tels fossiles sont généralement trop fragiles pour subsister intacts pendant des millions d'années. Sergio Sánchez Fenollosa, chercheur au sein de la fondation et co-auteur de l'étude, a déclaré que cette découverte révèle des aspects jusqu'alors inconnus de l'anatomie du Dacentrurus armatus et aide à expliquer comment les crânes des stégosauriens ont évolué.

A crushed dinosaur fossil, long forgotten in a drawer, has been reconstructed by a Virginia Tech undergraduate, unveiling a new species of early carnivorous dinosaur. The specimen, named Ptychotherates bucculentus, belonged to the Herrerasauria group and lived near the end of the Triassic period. Its discovery suggests this ancient dinosaur lineage persisted until the end-Triassic extinction.

Study links T. rex tiny arms to powerful skull evolution

20 mai 2026 Rapporté par l'IA

The tiny arms of Tyrannosaurus rex likely evolved as giant predatory dinosaurs shifted to using their massive skulls and jaws for hunting, according to new research. Scientists examined dozens of theropod species and found a strong connection between shrinking forelimbs and robust skulls. The study suggests this change occurred as predators targeted enormous prey.

Preserved blood vessels discovered in fractured T. rex rib

Researchers have identified preserved blood vessels inside a fractured rib bone from Scotty, the largest Tyrannosaurus rex specimen ever found. The structures, revealed using synchrotron X-rays, formed during the dinosaur's partial healing process 66 million years ago. The findings, published in Scientific Reports, offer new insights into dinosaur physiology.
