When the Mars 2020 rover lands on the Red Planet in February 2021, it will touch down in Jezero Crater, the site of a lake that existed 3.5 billion years ago. Now, two research teams have identified areas in Jezero Crater where the rover might find signs of ancient life.

New fossil treasure trove examined in TV special

When searching for dinosaur fossils, paleontologists know that there is a certain layer in the Earth where the fossils disappear. That layer marks when an asteroid slammed into Earth 66 million years ago, causing dinosaurs to go extinct and wiping out more than 75% of species.

Preserving the unique history of the La Brea Tar Pits

Black gooey methane bubbles pop on the surface of the Lake Pit outside the La Brea Museum in Los Angeles. It's the only warning of the sticky, heavy asphalt on the bottom of the pit.

Newly discovered stegosaurus fossil oldest in the world

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.

Why do coyotes still exist, but not saber-toothed cats?

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.

Early humans breastfed their young for a year, study says

Three million years ago, Australopithecus africanus was one of the first human ancestor species to live across the southern African grasslands and forests. A new study of fossil teeth suggests that like modern humans, they breastfed their babies for up to a year after they were born.

210,000-year-old human skull in Greece oldest found outside Africa

Two skulls found in a Grecian cave paint a surprising portrait of who lived there hundreds of thousands of years ago. One fragmentary skull has been dated to 210,000 years ago, and researchers believe that it is the earliest evidence of modern humans living in Eurasia, according to a new study. The other, more complete skull belonged to a Neanderthal who lived 170,000 years ago.

Dinosaur bones shimmering with opal reveal new species

A hunt for precious gemstones revealed the first fossil evidence of a dinosaur herd, including a previously undiscovered dinosaur species, in Australia. The new dinosaur fossil was found in an opal mine and has turned into the gem itself, making it the most complete opalized dinosaur skeleton in the world, according to a new study.
