Fossils of kinorhynch worms, also known as mud dragons, dating back more than 530 million years were recently unearthed in South China. Researchers say these ancient, microscopic worms fill in a huge evolutionary gap.
Fossils excavated from the fossil-rich Bighorn Basin in Wyoming shed new light on the different physical and behavioral traits of early carnivorous mammals known as hyaenodontids.
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.
Well-preserved mosasaur fossils represent a new smallish marine reptile that used binocular vision to hunt at night.
A new species of toothy pterosaurs named Cimoliopterus dunni sheds light on the evolution of these flying reptiles. However, its closest relatives are from England, suggesting the prehistoric animals were able to "island hop" as the North Atlantic Ocean widened during the Cretaceous.
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.
A fossil species of baleen whales sheds new light on the transition from ancient toothed whales to modern baleen whales.
Giant dinosaur footprints have surfaced along the Isle of Skye, suggesting long-necked sauropods once stomped across prehistoric Scotland.
Fossilized peach pits unearthed in China suggest the deliciously juicy fruits were around long before humans began domesticating them.
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.
Using a recently unearthed 90 million-year-old fossilized reptile skull, researchers reveal new insight regarding how snakes lost their limbs. It turns out the evolutionary characteristic of burrowing plays a key role.
A study of the porosity of ancient archosaur eggshells is tipping scientists off about the kinds of nests they once called home.
Using fossil teeth, researchers from Stony Brook University have found an ancient nectar-drinking bat was probably omnivorous.
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.
