Eighty million years ago, a ferocious predecessor of Tyrannosaurus Rex stalked the western shore of an ancient seaway that flooded through North America, slicing the continent in two.
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.
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.
Ocean acidification caused a mass extinction of marine life 66 million years ago, research into tiny shell fossils has shown. This could have implications for the current climate crisis, which is also making the oceans more acidic.
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. The asphalt seeps have been there for thousands of years, stemming from a nearby underground large petroleum reservoir called Salt Lake Oil Field.
Fifty-five paintings by a chimpanzee -- whose works have been acquired by the likes of Pablo Picasso, Joan Miró and the Duke of Edinburgh -- will go on sale at a London
Google kicked off the first day of Hispanic Heritage Month with a Doodle tribute to Mexican-American botanist and explorer Ynés Mexía.
After she hatched 66 million years ago, Victoria was the queen predator of her time during the Cretaceous period. But the Tyrannosaurus rex was struck down in her prime, before reaching her 30s, by an unlikely culprit.
Another puzzle piece has been recovered in the quest to understand a close and relatively recent addition to the human family tree.
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.
An international group of scientists has surveyed more than 2,500 coral reef systems across 44 countries to determine how to save them in the face of damage caused by climate change and humans, according to a new study.
About 19 million years ago, the world's largest parrot lived in New Zealand and used its massive beak to crack open food, according to a new study.
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.
A college student made the discovery of a lifetime on a recent paleontology dig when he unearthed a partial Triceratops skull.
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.
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.
Inside a Crimean cave was a gigantic ancient mystery just waiting to be uncovered: a bird so large that it weighed nearly as much as an adult polar bear.
Several weeks ago, construction workers digging near a Denver, Colorado, retirement home made a startling discovery: dinosaur bones.
Though today hyenas are often found stalking the African savannas and deserts, these predators once lived in a very different part of the world.
As cyclones and droughts are expected to grow in frequency and intensity while global temperatures rise, humankind's closest relatives will become increasingly vulnerable to extinction, scientists say.
After five fossil-less years, T. rex is roaring back to the Smithsonian.
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.
A previously extinct species of bird returned from the dead, reclaiming the island it previously lived on and re-evolving itself back into existence, scientists have said.
