Extinction

A retired chicken farmer found the rocks in the mid-1990s and donated it to the Australian Museum, where researchers have now named the newfound species Arenaerpeton supinatus.

The pair of newfound species, as well as two previously known species unearthed in the same place, rewrite what we knew about these prehistoric predators.

The fossil of an ancient sea squirt found in a collection at the Utah Museum of Natural History turned out to be the oldest of its kind.

Bones from the two ancient predatory species were found in the La Brea tar pits in what is now West Hollywood and showed signs of bone disease not normally seen in wild animals.

Scientists have solved the mystery of what Anomalocaris canadensis, an extinct apex predator, may have eaten.

The cave has been untouched for around 42,000 years. It also contained the bones and teeth of hyena pups, suggesting they raised their young there.

A team of researchers uncovered a tiny mosasaur fossil in the gray shale rocks of southern Utah — a discovery that could teach us more about this ancient sea beast's evolutionary history.

The newly discovered duck-billed dinosaur, Gonkoken nanoi, likely grew to around 13 feet long and weighed up to 1 ton, new analysis reveals.

Researchers believe the creature, named Nihohae matakoi, used its horizontal teeth to thrash at prey before gulping it down.

Scientists studied the fossilized teeth of megalodon and determined that the jumbo-size extinct species of shark was warm-blooded.
