Fifty million years ago, horses were certainly not the tall and regal animals they are today. In fact, they were about the size of your average pig, and boasted three or four thick-nailed toes, not hooves to boot! Now, a well-preserved fossil of an ancient pregnant mare is helping paleontologists learn more about what traits of ancient horses still persist in the animals today.
New fossil evidence is pointing to the possibility of a sixth mass extinction event in Earth's past, and this one may have helped usher in the largest "great dying" that that ever occurred. If that is right, the Permian period may have actually been hit with a two-punch knockout that caused more species loss than the infamous extinction of the dinosaurs.
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.
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.
Experts recently uncovered the fossil of a marine reptile whose remains had been gnawed on by long-gone scavengers of the ocean floor. This fossil is one of the first ancient parallels to modern "whale falls" and could help researchers better understand what corpse-eater ecosystems were like nearly 160 million years ago.
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.
Computerized tomography (CT) scans have revealed clues of the terrifying last moments of two baby mammoths' deaths. The conclusions that can be drawn from these scans are detailed in a recent study.
Paleontologists have discovered one of the most pristine patch of dinosaur tracks ever seen, and multitude of tracks indicates a massive herd roamed through Alaska 70 million years ago.
The long-dead 25-million year old seabird boasted a wingspan 21 feet wide, with even one of its wings dwarfing a California condor or a royal albatross.
The triceratops didn't always have the magnificent rack of horns that they are so well known for. The beaked dinosaur once sported a longer beak and shorter horns, but over the course of evolution it developed a more impressive and deadly display, according to a recent study.
A 9-year-old boy from Michigan unearthed a 10,000-year-old mastodon tooth from a creek near his home.
An international team of scientists discovered a world first when scanning a 250 million-year-old fossilized burrow from the Karoo Basin of South Africa: two unrelated vertebrate animals nestled together after being trapped by a flash flood event.
The first complete chemical analysis of feathers from the Archaeopteryx, a fossil linking dinosaurs and birds, reveals its plumage consisted of a light color with a dark edge and tip rather than all black, as previously believed.
