Fossils discovered in Australia reveal hundreds of new species, a pollen-covered insect, parasitic larva, and fish with last meals in their stomachs.
Scientists have uncovered the first fossil of a Homo naledi child. This ancestor lived about 250,000 years ago, likely alongside modern humans.
Experts reevaluated the human fossil record from the era between 129,000 and 774,000 years ago. That yielded a new species of human ancestor.
Paleontologists found 100 eggs and 80 skeletons from a dinosaur called Mussaurus at a site in Patagonia, suggesting the animals lived in groups.
Tardigrade fossils are hard to spot due to their tiny size. But experts found an ancient tardigrade hidden in amber from the Dominican Republic.
Researchers once thought humans couldn't have migrated down from Siberia into North America during the last ice age. New findings suggest otherwise.
A study suggests our mysterious cousins, the Denisovans, first occupied Denisova Cave. Then Neanderthals and modern humans joined them later.
Did dinosaurs go extinct after a space rock hit Earth 66 million years ago, or were they already declining?
A species of human ancestor called Homo longi, or "Dragon Man," lived in China 146,000 years ago. It may have interbred with ancient humans.
A human ancestor called Nesher Ramla homo occupied Israel and Arabia alongside humans at least 120,000 years ago, a new study says.
Giant rhinos were roughly the size of six elephants and they moved back and forth across Asia as their climate changed.
Before the discovery of a dinosaur fossil in 2004, many paleontologists thought they wouldn't find any dinosaur remnants in Australia.
Experts already knew T. rex was slow, with a max speed between 10 and 25 mph. But a new study suggests these predators preferred to walk even slower.
A study estimates how many adult T. rexes could live in a given area. That enabled researchers to calculate the total number of rexes that ever lived.
Researchers just sequenced the world's oldest known DNA, which came from mammoth teeth found in the Siberian permafrost.
Scientists mapped the genome of a saber-toothed cat species named Homotherium for the first time. The ancient cat’s genes reveal that it was a highly skilled pack hunter that could pursue its prey over vast distances. Homotheriums lived on five continents and roamed for millions of years before it went […]
Megalodons – huge, prehistoric sharks – reached lengths of 50 feet, with heads the size of cars. The predators are super-sized compared to other sharks, both living and extinct. But how megalodons achieved that massive size is a mystery. A new study suggests the sharks’ size could be explained in […]
