Paleontology

In a new documentary, paleontologists find that animals experienced a "wall of death" caused by a water surge after the asteroid hit, as "hell" rained down.

The rat-like creature — called a cynodont after its huge canine teeth — walked the earth with dinosaurs in the Triassic period.

Nick Longrich, a senior lecturer in evolutionary biology, told Newsweek that largely complete Triceratops specimens are "surprisingly rare."

The bobcat-sized creature has been called an evolutionary experiment, being the first known mammal to consume only meat.

Dortoka vremiri's aquatic environment and home in the relatively sheltered Hateg Basin helped it pull through the mass extinction.

Scientists found evidence of life created in the Cambrian Explosion in volcanic rocks drawn from deep within the Earth's mantle.

The largest megalodons lived in cooler waters found far away from the equator, scientists believe.

Bone fragments found in Italy were revealed to be from an ancient gray wolf that lived over 400,000 years ago.

The neotheropod fossil, found by professor Mark McMenamin, is thought to have belonged to a dinosaur measuring up to 30 feet long.

The 170 million-year-old fossilized reptile is believed to have been one of the largest animals to have flown in Earth's history.

The sharks lived between 20 million and 3.6 million years ago and it is thought they could grow up to 60 feet long.

The extinction of the planet's biggest sharks offers fascinating insights into their contemporary apex predators, great whites.

The fossilized remains of a 33-foot-long ichthyosaur, an extinct marine reptile, were uncovered in the U.K.

Evolutionary adaptations have excited researchers that have discovered a connection between mammals today and predators from about 300 million years ago.

A woman noticed the "interesting" and unusual artifact while picking up trash along a Virginia beach.

A local museum told Newsweek the juvenile skeleton of the Parrosaurus missouriensis will be on display for visitors to see starting next month.

The dinosaur, dubbed Berthasaura leopoldinae, represents a new species.

The footprints were found at Picket Wire Canyonlands, which is home to the largest dinosaur track site in North America.

The viral video led many to claim it as evidence of Noah and his Ark, but paleontologists told Newsweek there's a far more likely explanation.

The discovery is the oldest known footprint ever found of hominins.

Julian Gagnon was out with his parents at Dinosaur Hill Nature Preserve in Rochester Hills, Michigan when he came across what he thought was a "dragon's tooth."

The fossils, which date to between 66 and 68 million years ago, could also represent a new species altogether, according to paleontologists.

Comparing the Ulughbegasaurus to the ancestor of the T. rex is like comparing a grizzly bear to a coyote, said a researcher who helped identify the huge reptile.

The approximately 2,200-pound dinosaur is believed to have been the apex predator of its ecosystem.

The animal, estimated to be 10 feet long and weighing around 1,320 lb, would likely have been a top predator like the killer whale of today.

The site contains the preserved remains of Jurassic-era echinoderms, including starfish, sea urchins and sea cucumbers.

"It was surprising, and I didn't really understand the impact of it in the beginning," said the woman who found the fossil while visiting her son on the dig.

The YouTuber, who has found hundreds of tiny shark teeth and several whale skulls, began posting videos on his channel Mamlambo Fossils two years ago.

Researchers estimate that the species could have reached 25-40 meters (82-131 feet) in length.

The boy and his family were vacationing on a South Carolina beach when the huge fossil was uncovered.
