Fossils

Sotheby's is auctioning one of the largest and most complete T. rex skeletons ever found.

This T. Rex Fossil Could Fetch the Largest Sum of Any Dinosaur Ever Auctioned. Scientists Worry They’ll Lose the Chance to Study It

Bids on “Gus” will start at $19 million, a steep price for public institutions. Specimens in private collections can be harder for researchers to examine, and they’re practically impossible to include in studies in top-tier scientific journals

About two-thirds of the analyzed fossils were bent left, which means that the animals were curved right when they were alive.

Meet the Earliest Known ‘Right-Handed’ Animal, a Worm-Like Creature That Lived About 550 Million Years Ago

During the Ediacaran period, the critter wriggled around on the ocean floor of what’s now South Australia and preferred to turn right, a fossil analysis suggests

Dinosaurs and other animals might have eaten the fruits of angiosperms during the Late Cretaceous.

Early Flowering Plants May Have Relied on Dinosaurs to Eat Their Fleshy Fruits and Spread Their Seeds

According to fossils preserved by volcanic ash, the plants, known as angiosperms, began producing relatively large, blueberry-size fruits millions of years earlier than previously thought

After Decades of Debate, Scientists Say These Fossils Belong to the Largest Known Scorpion, Which Lived 415 Million Years Ago

Researchers have wondered whether Praearcturus gigas was a giant crustacean called an isopod or some other creature. A new analysis of museum specimens suggests that it was a scorpion that stretched more than three feet long

The bone was collected in December 1985 by the late geologist Mike Thomson, who described it as a "vertebra of large reptile" in his field notebook.

A Fossil From Antarctica Sat in a Drawer for 40 Years. It Turned Out to Be the First Dinosaur Bone Ever Found on the Continent

After being forgotten for decades, the mysterious tail vertebra has finally been identified as part of a titanosaur. The discovery helps researchers understand how dinosaurs may have traversed Earth’s southernmost regions

New Research

Did These Prehistoric Primates Really Bury Just Their Female Dead Deep in a Cave?

Researchers say that the fossilized bones of “Homo naledi,” so far found exclusively underground in South Africa, lack a key genetic male marker

This Strange, Feathered Dinosaur May Have Glided Between Trees Like a Flying Squirrel to Hunt Birds 120 Million Years Ago

A fossil of the creature provides the first evidence that microraptors lived in what is now northwestern China. Its discovery might also solve an ancient murder mystery

Two fossils of juvenile embolomeres—crocodile-like creatures, illustrated here—suggest that they did not undergo metamorphosis to become adults and that the ancestors of today’s birds, mammals, reptiles and amphibians might not have had a tadpole life phase.

A Vietnam Veteran Collected Fossils for 66 Years. One, Mislabeled ‘Baby Lamprey,’ Made Paleontologists Reconsider How Vertebrates Moved From Water to Land

The fossil turned out to be a hatchling of a crocodile-like creature, and it suggests, according to a new study, that early animals did not use metamorphosis to evolve to dwell on land

Scientists explored a tiny portion of the site during more than 30 dives with a submersible.

Scientists Discover the World’s Largest, Deepest Whale Graveyard, Where Cetacean Remains Have Been Piling Up for Five Million Years

The massive necropolis, located deep in the southeastern Indian Ocean, is teeming with marine life supported by the whale carcasses, including many suspected new species

Researchers weren't sure what drove some theropods, like T. rex, to evolve tiny arms relative to their body sizes.

Tyrannosaurus Rex and Other Terrifying Predatory Dinosaurs Had Itty-Bitty Arms. Scientists May Have Finally Figured Out Why

A new study suggests that certain theropods—two-legged, mostly meat-eating dinosaurs—had shrunken forelimbs as an evolutionary trade-off for their strong skulls

A limestone pigeon sculpture from Cyprus, dated between 600 and 480 B.C.E.

Pigeon Bones Found at an Ancient Cyprus Settlement Reveal That Our Relationship With These Birds Began Earlier Than We Thought

Before common pigeons were considered urban pests, people domesticated them and relied on them for meat, fertilizer, messages and more. A new study suggests humans have lived alongside the winged creatures for at least 3,400 years

Enormous dinosaurs like the Brachiosaurus in this illustration evolved multiple times over millions of years.

What Was the Biggest Dinosaur? Fragmentary Fossils Make It Hard to Tell

Pinning down the most titanic of the large sauropod dinosaurs is not an easy task, since the odds were generally against the biggest ones being buried and preserved

Paleontologists Discover an Ancient Marine Reptile They’ve Dubbed the T. Rex of the Sea, Crowning Another King of the Cretaceous

Scientists figured out that the predators were lumped in with a previously named mosasaur species. The new one, called Tylosaurus rex, could grow to 43 feet long, about the length of a school bus

Artist's reconstruction of newly described koala species. 

A Dimpled Koala Fossil Found in a Cave in Western Australia Revealed Why This Previously Unknown Species Went Extinct

The new study found that they lost their arboreal habitat due to a drying climate, a dire warning for the modern-day marsupials that face a similar threat

Nagatitan chaiyaphumensis was a long-necked, plant-eating dinosaur that lived in what is now Thailand between 100 million and 120 million years ago.

Cool Finds

A Man Spotted Strange-Looking Rocks Near a Pond in Thailand. They Turned Out to Be the Bones of a Massive New Dinosaur Species

Paleontologists have dubbed the long-necked, plant-eating creature “Nagatitan chaiyaphumensis.” It’s the 14th named dinosaur from Thailand, and it might be the biggest one ever found in Southeast Asia

About 50 organisms have been named for David Attenborough or elements of his legacy, from an orchid to a marine worm to one of the earliest known predators.

David Attenborough Has Inspired Countless Scientists. To Mark His 100th Birthday, Here Are Ten Living Things They’ve Named After Him

Researchers around the planet grew up watching documentaries hosted by the English broadcaster and naturalist, which sparked their love of the natural world. Now, their discoveries become tributes to his legacy

Cool Finds

This Bone-Crunching Octopus Was Nearly the Size of a Semitruck and May Have Feasted on Giant Reptiles 100 Million Years Ago

The massive invertebrates may have been top predators, according to an analysis of their fossilized jaws. The work suggests that ancient oceans weren’t completely ruled by spine-bearing creatures, as previously thought
