Paleontólogos encontraram o crânio de estegossauro mais bem preservado já descoberto na Europa em um sítio em Riodeva, na Espanha. O fóssil pertence à espécie Dacentrurus armatus e data do período Jurássico Superior, há cerca de 150 milhões de anos.

Pesquisadores da Fundación Conjunto Paleontológico de Teruel-Dinópolis identificaram o espécime durante escavações no sítio Están de Colón, na Formação Villar del Arzobispo. O crânio oferece detalhes anatômicos raros, uma vez que tais fósseis costumam ser frágeis demais para sobreviver intactos ao longo de milhões de anos. Sergio Sánchez Fenollosa, pesquisador da fundação e coautor do estudo, afirmou que a descoberta revela aspectos até então desconhecidos da anatomia do Dacentrurus armatus e ajuda a explicar como os crânios dos estegossauros evoluíram.

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

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.

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.
