A few vertebrae and the upper arm bone of a previously unknown species of stegosaurus have been found in the Middle Atlas Mountains of Morocco. And despite the lack of a complete skeleton, scientists say that at 168 million years old it's the oldest known stegosaurus yet found.
Thousands of years ago, animals and the predators who tried to attack them became trapped in the La Brea Tar Pits, providing a treasure trove of fossils for research. Now, a detailed study of the predators found trapped in the tar is shedding light on why some are still found on Earth today but others went extinct.
The controversial listing for sale of a rare infant tyrannosaurus fossil has caused outrage in the normally sedate world of paleontology.
An international team of scientists has discovered a fossil graveyard containing what it describes as "extraordinary evidence" that an asteroid that hit the Earth around 66 million years ago was responsible for the extinction of the dinosaurs.

A newly discovered fossil site in China that dates back 518 million years contains more than 50% previously unknown species, according to a new study. The well-preserved Qingjiang site is helping scientists to fill gaps in the fossil record and provide a clearer picture of some of the earliest animal ecosystems.
Kangaroos and wallabies weren't around in Australia 125 million years ago, but small herbivorous dinosaurs that also bounded around on powerful back legs were. Researchers discovered five fossilized jaws from a previously unknown dinosaur in the state of Victoria that was about the size of a modern-day wallaby.
Tyrannosaurus rex wasn't always the king of the dinosaurs. Before they became towering predators, tyrannosaurs started out much smaller, and a newly discovered fossil is helping fill the gap between those two extremes.
If humans had lived 200 million years ago, they would have marveled at the largest dinosaur of its time. It's name means "a giant thunderclap at dawn."
The oldest known animal in the geological record has been identified, in a discovery that scientists are calling "the Holy Grail of palaeontology."
Heavy rains in Maryland recently unearthed a prehistoric find in an unusual place.
Finding fossils can be a fact of life for construction crews excavating in California. That's what happened when crews broke ground to begin the new Bay Area Calaveras Dam in 2013. They just didn't expect to find so many.
Rare prehistoric dinosaur footprints discovered in the UK have shed new light on the middle Jurassic period, according to a new report.
Fossils uncovered in Germany show that butterflies and moths may have been around for at least 200 million years.
