Fossils

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.

Researchers have found around 50 footprints at two sites on the island.

The researchers argue that green seaweeds like these are the descendants of all land plants that exist today.

"In recent years we have seen increasing evidence that Neanderthals were more sophisticated than previously thought," researcher Emma Pomeroy said.

The animal is one of the oldest tyrannosaur species ever discovered in North America.

The shark was likely similar in size to great whites, which grow to an average of around 15 feet.

Researchers identified digestive tracts in an extinct worm-like creature known as Cloudina.

The latest known fossils belonging to extinct human species dated to between 117,000 and 108,000 ago.

New discoveries in Bavaria of an ape with "orangutan arms" but human-like legs has the science community excited about connecting the dots of evolution between great apes and humans.

A recently published study describes the fossilized remains of a surprising assemblage of creatures from the Late Jurassic period, including the skull and teeth fragments from a large pliosaurus.

The creatures are invisible to the naked eye, measuring around 100 micrometers long—about as thick as a human hair.

The latest find is surprising because shark skeletons are made of cartilage—a rubbery tissue that doesn't preserve as well as bone.

The latest discovery comes four years after a similar find in the same region of Argentina.

The dinosaur could bite with about three times the force of large crocodiles or great white sharks.

The findings suggest that these early large, complex lifeforms were more like modern animals than previously thought.

The fossils are 15 million years older than any others belonging to the tyrannosauroid family that have been found in North America.

The evidence was found in a rock deposit in Central Africa, although some experts have urged caution over the claims.

The clutch of babies were likely still inside their eggs.

Scientists named them Xenomorphia, after the bloodthirsty, chest-splitting creatures from the Alien movies.

These sharks are now the most popular in the ocean.

The animal measured between 13 feet to 16 feet long and stood 3-and-a-half feet tall at the hips.

The dinosaur stood over 14 feet tall and weighed up to 10 tons.

The organisms have been named after former President Barack Obama and renowned British naturalist Sir David Attenborough.
