Dinosaurs had a banner year in 2015. Several new species were unearthed, each revealing some interesting characteristics of these fascinating prehistoric creatures.
Following the mass extinction of dinosaurs, mammals were able to rapidly diversify and radiate without the threat of predation.
An extinct group of marine reptiles known as plesiosaurs had a very unique body structure. New computer simulations suggest the animals likely used it to move through the water like a penguins.
A new dinosaur species with a "sail" on its back was recently unearthed in northeastern Spain. Researchers say this mysterious "sail" helped the dinosaur regulate its body temperature or store fat.
Researchers from University of Queensland have identified one of Australia's newest dinosaurs, Kunbarrasaurus. This dinosaur's unique characteristics suggest it is a distinctly different species than previously classified.
Scientists have discovered a new member of the Ceratopsia dinosaur family, but it lacked horns and was the size of a small dog.
When dating volcanic ashes from the Late Triassic Period from Argentina, researchers discovered dinosaurs evolved more rapidly than previously thought. In fact, the prehistoric animals evolved roughly five million years or less after their ancestors emerged.
Giant dinosaur footprints have surfaced along the Isle of Skye, suggesting long-necked sauropods once stomped across prehistoric Scotland.
Ceratopsian dinosaur from the Late Cretaceous period of eastern North America evolved differently when isolated from their western relatives by a division of water 66 million years ago.
A study of the porosity of ancient archosaur eggshells is tipping scientists off about the kinds of nests they once called home.
A recent analysis of eight fossilized teeth revealed the true identity of a dinosaur species incorrectly classified years ago. It turns out that Dimetrodon borealis actually represents the first Canadian Dimetrodon, or terrestrial animal with steak knife-like teeth.
After reevaluating the ankle bones of modern birds and comparing them to dinosaurs, researchers confirmed a developmental pattern linking the two species.
A new duck-billed dinosaur, named Probrachylophosaurus bergei, which possessed a relatively short skull crest, represents an evolutionary link between its non-crested and large-crested ancestors.
Researchers University of Kansas recently uncovered fossils representing the largest known feathered raptor. The species has since been named Dakotaraptor and it's closing the gap in the evolutionary gap between dinosaurs and modern birds.
