Fossils

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

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

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.

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

From preserved plants to T. rex, the material found in these Late Cretaceous rocks has resulted in countless breakthroughs for paleontologists

British geologist and naturalist William Pengelly identified the object as a badger tooth.

Long Misidentified, This Seal Tooth Pendant Was Carefully Crafted by a Prehistoric Human Roughly 15,000 Years Ago

Discovered in 1867, the artifact raises new theories about the Magdalenian people who inhabited southwest England during the Late Upper Paleolithic period

This Nearly 300-Million-Year-Old Mummified Reptile Reveals the Evolutionary Origins of How We Breathe

Unusually well-preserved fossils have provided the earliest known evidence of a land vertebrate that could pump air in and out of its chest using muscles between the ribs—the same strategy used by modern mammals, reptiles and birds

An artistic rendering shows the mysterious animal, which researchers now say was a nautilus relative, in its prehistoric environment.

This Fossil Held the World Record for the Earliest Known Octopus. Turns Out, It’s Not an Octopus After All

New research suggests the 300-million-year-old specimen is actually a relative of the nautilus

These 17-Million-Year-Old Fossils Could Rewrite the Evolutionary Tree of Apes—Including Humans

Jawbone fragments and teeth from a previously unknown species hint that the evolution of modern apes occurred in what’s now North Africa or the Arabian Peninsula, rather than in East Africa

An artist's depiction of dogs living alongside humans at a site in Turkey 15,800 years ago

Scientists Identify the World’s First Known Dog, Which Pushes Back the Animals’ Genetic Record by About 5,000 Years

Two new ancient DNA studies suggest that domesticated dogs were widespread in western Eurasia more than 14,000 years ago
