Fossils

"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.

Bloodthirsty rivalry may have driven the rapid evolution of these fearsome beasts.

The creatures had heads like crocodiles and tails like fish.

They predate mammals, dinosaurs, and even fish.

This was from long before the dinosaurs.

These rocks formed at the bottom of ancient lake beds between three and four billion years ago, when the Martian surface was abundant in water and its climate was warmer.

The asteroid and its after-effects ushered in a great extinction event that wiped out some three quarters of all plant and animal life, including dinosaurs and most birds.

Around 550 million to 540 million years ago, there was a remarkable explosion in the diversity and complexity of animal life on Earth.

Researchers say the fossil underscores how little we know about these mysterious ancient beasts.

The fossil is from one of the most successful species to have lived on Earth.

Scientists now believe humans stalked and then confronted a giant ground sloth thousands of years ago in New Mexico.
