Today is National Fossil Day, acknowledging the great importance of these ancient remains. These days, researchers use fossils to trace the evolution of life's ancestors, looking to birds in particular in an effort to better understand how evolution shapes our world.
The 200 million year-old fossil of a toothy bipedal dinosaur was recently discovered in Venezuela, and it's the first carnivorous hunter ever found in the region. Researchers are now saying that it was likely one of the survivors of the end-Triassic mass extinction event, making it a pioneer of "king lizard" dominance.
Dinosaurs were the largest animals ever to walk the Earth, and with thousands of them roaming around competing for the same food resources, it's a wonder they managed to survive. But new research indicates that differing dino diets allowed them to peacefully coexist, especially at dinnertime.
Although we can now appreciate that dinosaurs led to the rapid rise of birds over the course of millions of years, one of the last nagging doubts about their link may be settled by a new study that shows how dinosaur arms evolved into bird wings.
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.
