About 210 million years ago, the supercontinent of Pangea was just starting to break up. At the time, dog-sized dinosaurs hid from the predators at the top of the food chain: reptiles called phytosaurs and rauisuchids. Now, with the discovery of an ancient tooth, scientists have found that these predators may have interacted with each other far more often than previously thought.
New research has found that dinosaurs, massive prehistoric meat-eaters, rapidly gave rise to the thousands of bird species that we see today.
A newly discovered armored fossil from New Mexico has just been confirmed as a new species in the ankylosaurid dinosaur family. Researchers from Alberta now suspect that the armored giant is not only related to its cousins up north, but perhaps even made Alberta its stomping grounds as well.
New research shows that the same meteorite that caused dinosaurs to go extinct also decimated the evergreen flowering plants of the time, but the harsh conditions that followed the killer impact favored fast-growing, deciduous plants, and helped ancient forests bloom.
A newly discovered species of pterosaur has been named after the dragon-like creatures from the visually stunning 2009 movie Avatar, as it happens to sport s similar skull to the four-winged creatures of the sci-fi blockbuster.
Scientists have unearthed Spinosaurus aegyptiacus, which was not only the biggest and baddest of all the carnivores, but also appears to be the first known swimming dinosaur, according to new research.
A new species of titanosaurian dinosaur was recently discovered in Tanzania, shedding light on a unique species that thrived during the final period of the dinosaur age.
Scientists have discovered the skeleton of a previously unknown, utterly massive dinosaur in Argentina that may possibly be the largest dinosaur ever to walk the Earth.
A hiker discovered a set of 125-million-year-old dinosaur footprints in Utah, and soon the public will be given the chance to see these extraordinary tracks.
Giant toothless pterosaurs once dominated the skies, and new research suggests that these ancient creatures played an important role in the Late Cretaceous ecosystem.
Experts have recently discovered a very old dinosaur that is not only the first named dinosaur fossil to be discovered in Venezuela, but also in all of northern South America. It also provides some new clues about what happened after the Triassic extinction, the first of two major dinosaur extinction events.
Researchers are suggesting that some dinosaurs likely survived the mysterious mass extinction of the Earth's prehistoric giant lizards because they had shrunk. Theropods, the dinosaur lineage that experts believe was the precursor to modern birds, were likely the only dinosaurs to shrink over time, according to a recent study.
It's not exactly Jurassic Park's perfectly preserved mosquito in amber, but it's still an incredible find. Researcher have uncovered fossils of blood-suckers dating back to an estimated 130 million years ago, making them the oldest fossils of blood-feeding insects ever found.
Fossils of feathered dinosaurs are no longer as terribly rare as they once were, even if they still are exciting finds. However, so far all feathered dinosaurs have been the flesh-eating two-legged raptors theorized to be the ancestors of modern birds. Now paleontologists have found evidence that some large plant eating dinos also sported bristly feathers, changing the rules for predicting who likely had plumage.
What's worse than one Tyrannosaurus rex? Three. Newly discovered T. Rex tracks show that three of these ancient predators stalked together across a mud flat in ancient Canada supposedly in search of prey, backing the theory that they hunted in packs, according to a new study.
