Paleontologists have found the best-preserved stegosaur skull ever discovered in Europe at a site in Riodeva, Spain. The fossil belongs to Dacentrurus armatus and dates to the Late Jurassic period around 150 million years ago.

Researchers from the Fundación Conjunto Paleontológico de Teruel-Dinópolis identified the specimen during excavations at the Están de Colón site in the Villar del Arzobispo Formation. The skull offers rare anatomical details because such fossils are usually too fragile to survive intact over millions of years. Sergio Sánchez Fenollosa, a researcher at the foundation and co-author of the study, said the discovery reveals previously unknown aspects of Dacentrurus armatus anatomy and helps explain how stegosaurian skulls evolved.

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

May 20, 2026 Ti AI ṣe iroyin

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.
