This list of the Paleozoic life of Pennsylvania contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Pennsylvania and are between 538.8 and 252.17 million years of age.
A new species of dinosaur has been identified more than a decade after a large number of ancient skeletons were found in Spain -- and researchers expect more species to be discovered. The ...
Dinosaur skull found in New Mexico is a cousin of T. rex — and even bigger, experts say Dig at ancient cemetery reveals colorful masks and artifacts. See the finds from Egypt
The holotype of S. angustirostris is a skull and postcrania, so the cranium of the species is well-described. Bell et al. re-evaluated the entire species in a 2011 publication with Acta Palaeontologica Polonica. Their description found the skull to be generalized among hadrosaurines, and are much larger than any skulls of S. osborni. The most ...
A nearly complete and intact dinosaur skeleton has been excavated in France. The specimen is a Titanosaur, one of the largest dinosaurs of its time. 70 million-year-old giant dinosaur skeleton ...
The species is known mainly from a single skull, plus a few extremely thick skull roofs (at 22 cm or 9 in thick). More complete fossils would come to be found in the following years. Pachycephalosaurus was among the last species of non-avian dinosaurs on Earth before the Cretaceous–Paleogene extinction event.
