More than 500 million years ago, funny-looking Ediacaran organisms dominated the planet's oceans. The nature of these creatures have been a long-standing mystery, but now scientists say they are actually Earth's first animals.
A new extinct species of shark was identified using fossilized bone found in California, North Carolina, Peru and Japan. The 20-million-year old fossil coudl be related to the infamous Megalodon.
Pareiasaurs were massive herbivores that ruled the Earth long before dinosaurs. Despite their stumpy limbs, researchers have found China natives were actually world travelers, able to mingle with relatives in Russia and South Africa.
Prehistoric claw marks found inside Australia's Tight Entrance cave reveal a bit more about the continent's extinct predator, the marsupial lion. It turns out the animals were agile hunters that reared their young inside the cave.
Stegodon dinosaurs are thought to be prehistoric cousins of modern elephants. A team of scientists in Pakistan recently unearthed a 1.1 million-year-old tusk belonging to one of these prehistoric animals in a central province of Punjab.
Fossils of a giant, flightless bird have finally been analyzed, and confirm a prehistoric species known as Gastornis roamed the Arctic 53 million years ago. While the climate was much different then, scientists warn that climate change could one day invite more diverse species to the North.
A new species of dinosaur thought to be the oldest Jurassic dinosaur ever found in the U.K. was named Dracoraptor hanigani or “dragon robber." Researchers say this find is remarkably valuable, as it sheds light on the diversification of dinosaurs in the early Jurassic – a period that remains rather hazy to paleontologists.
The American Museum of Natural History in New York City has a newly unveiled dinosaur skeleton that is the world's largest. It has been identified as a new species of titanosaur, but scientists haven't named it yet.
A complete dinosaur skeleton of a baby Chasmosaurus has revealed some interesting characteristics of horned dinosaurs, which are characterized by a large bony appendage known as a frill.
A dinosaur species known Protoceratops andrewsi sported an ornamental head appendage called a frill that was likely used to attract suitable mates and helped to assert social dominance.
Fossils unearthed from the Sahara Desert in Tunisia reveal the largest-known ocean-dwelling member of the crocodile family tree. This prehistoric predator dates back 130 million years, changing the way scientists view the mass extinction that is thought to have occurred at the end of the Jurassic period, 145 million years ago.
Exceptionally well-preserved fossils of three 10-armed squid ancestors were recently found in Germany. The specimens reveal how these creatures were able to swim through Jurassic seas so effectively.
Paleontologists suggest recently discoverd foot scrapes across several Colorado outcrops were made by large dinosaurs that competed in dance-offs to woo their mates.
A meter-long shell belonging to a glyptodont – a giant prehistoric kind of armadillo – was found recently along a riverbank in Buenos Aires, Argentina.
