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.

Dinosaur tracks from 132 million years ago discovered near Knysna

Scientists have uncovered more than two dozen dinosaur tracks dating back 132 million years in a small rock outcrop near Knysna, South Africa. These footprints, the youngest known in southern Africa, indicate dinosaurs persisted in the region into the early Cretaceous Period. The discovery challenges previous gaps in the local fossil record following ancient lava flows.

Scientists have determined that Nanotyrannus was a mature, separate species rather than a juvenile Tyrannosaurus rex. A new study analyzed a tiny throat bone from the original fossil, revealing growth patterns indicating adulthood. The findings, published in Science, challenge decades of debate over the dinosaur's identity.
