The fossilized discovery […]

Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by finding a key piece of evidence: asteroid dust inside the impact crater. Death by asteroid rather than by a series of volcanic […]

Artist’s rendering of a comet headed towards Earth. New theory explains possible origin of the Armageddon-causing object. It forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s known, left behind a crater off the coast of Mexico that spans 93 miles […]

Braincase and endocast of Thecodontosaurus antiquus. From CT scans of the braincase fossil, 3-D models of the braincase and the endocast were generated and studied.

By cutting into fossils and examining growth rings, scientists learned how predatory dinosaurs got so big. Tyrannosaurus rex was one of the biggest meat-eating dinosaurs of all time — it measured up to 42 feet long from snout to tail and would have weighed in at around 16,000 pounds. And it […]

Pterosaurs with these types of beaks are better known at the time period from North Africa, so it would be reasonable to assume a likeness to the North African Alanqa.

Duckbill dinosaurs evolved in north America, spreading to South America, Asia, Europe, and finally Africa. Credit: Raul Martin The first fossils of a duckbilled dinosaur have been discovered in Africa, suggesting dinosaurs crossed hundreds of kilometers of open water to get there. The study, published in Cretaceous Research, reports the new dinosaur, Ajnabia […]

Buriolestes schultzi brain. Credit: Márcio L. Castro The study of the brain of extinct organisms sheds lights on their behaviors. However, soft tissues, like the brain, are not usually preserved for long periods. Hence, researchers reconstruct the brains of dinosaurs by analyzing the cranial cavities under computed tomography. It demands […]
