Fossils

The once-in-a-lifetime skeleton is the most complete gomphothere fossil from its time period discovered in Florida.

"I thought right away that it looked similar to a shark's tooth, but was confused because it was quite a large size," Rachel Shill Cook told Newsweek.

The fossil remains of the new species date to a period in the Earth's history that followed our planet's worst mass extinction event.

The fish, whose fossil was unearthed in South Africa, lived around 419 million years ago.

"We could not believe our eyes. Neither of us had ever seen a tooth this big," Leah McLamb told Newsweek. Today's largest white sharks grow up to 20 feet long.

Bones believed to be of the antique bison, an extinct species of bison larger than modern day bison that died out around 10,000 years ago, have been discovered.

A discovery suggests that an ancient species acquired a key evolutionary innovation before a mass extinction event, enabling related creatures to dominate the Earth for millions of years.

The Galápagos Islands are a remote archipelago in the Pacific Ocean home to a wide variety of unique flora and fauna species.

"Part of its root was sticking up a bit and I pulled it up," a diver said. "Later on the boat, I realized it was bite marks."

The ribs of the near-complete fossil, estimated to be at least 85,000 years old, were seen sticking out of the ground by an archaeologist and a local collector.

The footprint was found in Alaska's Aniakchak National Monument and Preserve, and is the first evidence of T. Rex in the region.

The six-foot-long Whatcheeria was discovered in a limestone quarry near the town of What Cheer, Iowa.

The extremely rare fossil belonged to an animal that has not been seen since the last Ice Age.

The fossils were well-preserved with soft tissue, an extremely rare discovery.

The casts have appeared after decades of obscurity where no copies of the long-lost fossil were known to exist.

The fossil, an ancestor of turkeys and grouse, was found in modern-day Nebraska, and lived around 11 million years ago.

Paleontologists working in Scotland have uncovered a near-complete skeleton of an early reptile from the middle Jurassic period.

"The critical context of the fossil" is lost when it is removed by non-scientists, paleontologist Justin Adams told Newsweek.

"Our finding helps fill in a previously missing piece of the puzzle," Tom Cullen, one of the researchers in the study, told Newsweek.

The sturgeon fossils, discovered at the Hell Creek Formation, were likely buried by a "huge tidal surge" from the asteroid that killed the dinosaurs.

The prototype wind turbine generated 359 megawatt-hours worth of electricity in 24 hours, more than any other has in the same amount of time.

Scientists have vocally protested the auction of large dinosaur specimens in the past, many of which sell for millions of dollars.

Paleontologists have so far uncovered the dinosaur's tail and its foot, and believe an entire skeleton lies within the rock, completely covered in skin.

Several species feed like this fossilized creature might have, regurgitating their guts before re-swallowing them.

Named Opisthiamimus gregori, its fossilized remains were entombed in rocks from a river floodplain dating back to the Late Jurassic in present-day Wyoming.

The two fossilized eggs, which were filled with clusters of calcite crystals, are from a new species of dinosaur.

Researchers have discovered remains of a massive coral reef in a desert plain they previously thought was featureless.

Teeth are the most common megalodon fossil to be discovered. Some are bigger than a human hand.

Based on the dimensions on the scanner, the team estimated the shape was "weighing in at 40 tons!"

Pachykrokolithus excavatum lived with the last dinosaurs, and the crocodile's eggshells were found in northeastern Spain.
