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

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 whale is thought to be around 1,000 years old and could have measured more than 65 feet in length—but researchers are not sure exactly what it is.

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

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.

The ancient specimen is the largest known amber-preserved flower fossil to date.

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.

"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 dinosaur fossil, uncovered in the Gobi desert in Mongolia, was "beautifully preserved," providing paleontologists with a wealth of information.

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 contents of the ancient seawater trapped in rocks for 390 million years may also give scientists clues about the climate on ancient Earth.

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

Footprints of the extinct wild super-cow reveal the secrets of this long-lost animal's past.

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.

Researchers have identified what looks like a fossil from the extinct shark—and the discovery could provide evidence about its migratory habits.

Exquisitely preserved nervous system discovered in scalidophoran worms for the first time.

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

A new species of prehistoric marine reptile has been identified in the Wyoming badlands.

Paleontologist Ashby Gale told Newsweek that the tooth, belonging to the biggest shark species to ever live, dates back between 3.6 and 15.9 million years.

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.
