Fossils

The huge extinct shark teeth can measure several inches in length and can be worth thousands of dollars.

The creature is the earliest known species of a group of sea scorpions called mixopterid and could have been an important predator in the shallow seas of China.

A Florida man found a gigantic fossilized megalodon tooth while diving in Florida waters, months after getting attacked by a gator.

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 10-foot-long creature lived 43 million years ago; scientists named it for the Egyptian god of the dead.

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.

"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.

Experts from multiple European institutions have proven that fossilized teeth dating back 138 million years are from a previously unknown species of extinct sea crocodiles.

"It's my first whole megalodon tooth," said Jacob Danner, who spotted the fossil during an early morning walk.

The fossil of the "river boss" crocodile was found in Australia over 100 years ago.

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.

The collection of mammoth bones has been taken by the government of Yukon for further investigation.

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

The paleontologists who made the find believe that it could take years to exhume the remains completely.

Hundreds of specimens have been recovered so far, including a practically intact set of mastodon tusks.

The man was walking along a river when he made the amazing discovery, which experts estimate to be around 84 million years old.

The fossil of an armored shark found on the World Heritage Site of the Jurassic Coast of Dorset, England is of a "news species," scientists named it Durnonovariaodus maiseyi. The extremely rare fossil is about 150 million years old.

The Rubbish Paddlers said it was "amazing" to know that what is now Scotland used to be located near the equator with "beautiful corals like this one."

Paleontology hobbyists Derek Demeter and Henry Sadler made the extraordinary find, along with several others, on April 25.

The creature has been identified as a type of hadrosaur, but it is unlike any others in that category.

A fossil of the ancient shark, now named Dracopristis hoffmanorum, was found in 2013 by a team of researchers.

Finder Matthew Basak hopes to sell the tooth for $6,000 or more. Many are already on sale for thousands.

The film follows Mary Anning, an acclaimed (but often overlooked) English fossil hunter from the 1800s.

Researchers have discovered the fossilized remains of at least 40 different species of ancient shark in Mammoth Cave in Kentucky, dating back to around 325 million years ago.

"Diagnosis of aggressive cancer like this in dinosaurs has been elusive," said researcher Mark Crowther.

The fossilized excrement could help to shed light on what the extinct animal once ate.

The reptile is an early member of the animal group Ornithodira to which both dinosaurs and pterosaurs belong.

"The finding of the actual preserved stomach contents from a dinosaur is extraordinarily rare," said researcher Jim Basinger.

Researchers reviewed a group of fossils from an area of the Moroccan Sahara, which includes a host of large dinosaurs, pterosaurs, crocodilians, and other animals.
