Paleontologists found 100 eggs and 80 skeletons from a dinosaur called Mussaurus at a site in Patagonia, suggesting the animals lived in groups.
By studying hair from giant prehistoric sloths called mylodons, experts have discovered the animals scavenged for meat in addition to eating plants.
Giant rhinos were roughly the size of six elephants and they moved back and forth across Asia as their climate changed.
A calculation widely used by scientists since 2002 did not stand up to the scrutiny of high school students on a field trip.
By studying ancient shark scales collected 3 miles under the Pacific waves, experts found that the animals almost went extinct 19 million years ago.
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.
The origin of the space rock that killed the dinosaurs has been a mystery. A new study suggests it wasn't an asteroid, but a comet fragment.
The “Dueling Dinosaurs” fossil is made up of intertwined T. rex and triceratops skeletons. The nonprofit organisation Friends of the North Carolina Museum of Natural Sciences bought it for $US6 million. The museum will display the fossils starting in 2022. Researchers there will examine the bones in detail and investigate […]
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 […]
A 67-million-year-old Tyrannosaurus rex skeleton named Stan sold for $US31.8 million at Christie’s auction house in New York City on Tuesday, making it the most expensive dinosaur skeleton ever sold. An anonymous buyer won the auction after 20 minutes of bidding. Only 50 or so T. rex skeletons have ever […]
New estimates suggest the megalodon – a giant, ancient shark – had a head about 15 feet long and a dorsal fin more than 5 feet tall. Researchers used the shark’s fossilized teeth and the proportions of its nearest living relatives, including the great white, to estimate the size of […]
Archaeologists in Mexico discovered a huge collection of mammoth skeletons buried under an airport construction site. At least 200 skeletons have already been unearthed, and many more await excavation. Paleontologists think that studying these mammoths could offer new insight into why the species went extinct 10,000 to 13,000 years ago. […]
Summary List Placement Have you ever wondered what the area around your hometown was like during the Cretaceous period, when the Tyrannosaurus rex roamed? How about before then, when Earth had just one supercontinent? Now you can find out. An interactive map developed by software engineer Ian Webster lets users […]
Researchers in Canada diagnosed a dinosaur with an aggressive type of bone cancer – the first time a dinosaur has received a confirmed cancer diagnosis. The dinosaur died “surrounded by its friends,” the scientists said, a finding that may offer insight into dinosaur social structures. Visit Business Insider’s homepage for […]
Earlier this month, paleontologists announced the discovery of the largest soft-shelled egg ever found. The researchers think the football-sized specimen, which was discovered in Antarctica, came from a giant, swimming reptile. But other scientists think the giant egg could have been laid by an early dinosaur. Visit Business Insider’s homepage […]
