Paleontologists

Scientists think a Nanotyrannus or a young Tyrannosaurus rex might have eaten the bird.

A 66-Million-Year-Old Feather Trapped in Dinosaur Poop Might Help Explain Why Some Birds Survived Mass Extinction

Discovered in Montana in 2016, the cherry-size coprolite contains feathers, bones and evidence of the bird’s last meal before the creature was eaten by a theropod

Researchers estimate the T. rex was walking at a speed of roughly 3.4 to 4.5 miles per hour.

These Four Giant Dinosaur Footprints Discovered in North Dakota Might Represent the First Trackway Made by an Adult T. Rex Ever Found

A high school teacher first spotted the remarkable trail while volunteering on a paleontological dig. Researchers suspect a hulking, full-grown dinosaur marched through the then-swampy landscape roughly 66.5 million years ago

Miracinonyx trumani that lived in modern-day Wyoming hunted mainly herbivores, such as the Saiga antelope illustrated here, according to the study.

For Decades, Scientists Thought an ‘American Cheetah’ Once Roamed North America. Turns Out the Extinct Cat Wasn’t a Cheetah

Ancient DNA from fossils found in Wyoming and Canada’s Yukon Territory suggests the wild cat more closely resembled modern pumas than modern cheetahs

To Researchers’ Surprise, This Giant Dinosaur Laid Eggs in a Cold Climate

A new study suggests that titanosaurs used rotting vegetation to keep their eggs warm much like crocodiles do today

An artist's interpretation of what Chosha praecursor might have looked like while splitting its time between water and land 324 million years ago in what is now Texas.

This Ancient Insect Had 24 Legs—and Could Help Explain How the Ancestors of Modern-Day Bugs Took Over the Land

A previously undescribed critter that lived 324 million years ago appears to have been a transitional species that lived between land and sea. It could help researchers fill an 80-million-year gap in the fossil record of how crustaceans evolved into insects

Anderson Taylor stands behind display cases in the Cambridge Natural History Museum in Cambridge, Illinois.

An 11-Year-Old Boy in a Small Midwestern Town Just Became the Guinness World Record Holder for Being the Youngest Museum Curator

Four years after Anderson Taylor began collecting specimens, he opened the Cambridge Natural History Museum in Cambridge, Illinois, offering school tours and attracting visitors from across the region

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

Illustration of what Praearcturus gigas may have looked like

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

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

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

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

Mountains in Montana’s Makoshika State Park, where some of the Hell Creek Formation lies.

250 Places to Celebrate America

The Hell Creek Formation Is North America’s Legendary Boneyard. See the Top Five Discoveries Found in the Iconic Fossil Bed

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

An artistic rendering of the successfully hunted straight-tusked elephant, which would have been an incredible source of food for Neanderthals

After Nearly 80 Years of Doubt, Scientists Say a Spear Lodged Between Elephant Ribs Offers Evidence That Neanderthals Hunted Big Game

In 1948, amateur archaeologists unearthed the remains, which should have shifted researchers’ views of Neanderthals. But poor documentation sowed skepticism in the scientific community

Two researchers wore goggles, snorkels and wet suits while exploring the underground stream.

These Snorkeling Scientists Stumbled Upon a Surprising Trove of Fossils in a Texas Water Cave

They found remains of animals that have never been uncovered in Central Texas. The fossils hint that the region was warm, moist and forested 100,000 years ago

Spinosaurus was the largest and most aquatic of the spinosaurs, a group of dinosaurs with crocodilian snouts.

Was Spinosaurus Really a ‘Hell Heron’? Digging Into the Star of Netflix’s ‘The Dinosaurs’

With an incredible sail and heavy bones that might have acted as ballast, Spinosaurus seems primed for snatching fish. The creature has long captivated the public, from its early mysteries to the recent discovery of a new species

When tickets went on sale for the “Pokémon Fossil Museum" exhibition, eager fans overwhelmed the Field Museum’s website.

This Museum Is Using Pokémon to Teach Visitors About Fossils. Fans Are Waiting for Hours to Snag Tickets

“Pokémon Fossil Museum” in Chicago compares “fossil Pokémon” from the popular franchise to the real-world creatures they’re based on

An artistic representation of Sonselasuchus cedrus, which may have lived in the forests in what is now Arizona around 215 million years ago

This Ancient Reptile Started Life on All Fours. As It Grew, It Stood Upright and Started Walking on Two Legs Instead

Scientists have identified a strange early crocodile relative that may have looked somewhat like a flightless bird

Spinosaurus mirabilis prowled around what is now Africa some 95 million years ago.

This Massive, Meat-Eating Dinosaur Was a ‘Hell Heron’ That Waded Into Shallow Waters to Nab Slippery Fish

Paleontologists unearthed a new species of Spinosaurus in the Sahara Desert in Niger, a discovery that adds to the debate over whether the prehistoric creatures were fully or semi-aquatic

Based on Andrewsarchus’ skull size and the skull-to-body-size ratios of other hoofed predators called mesonychids, scientists estimated in 1924 that the beast was more than 12 feet long and about 6 feet tall. Reassessments of Andrewsarchus’ evolutionary tree, however, suggest this estimate is inaccurate.

This Giant Carnivore Ran on Hooves. Scientists Are Investigating Its Massive Skull and Crushing Teeth to Decipher the Beast’s True Nature

For more than a century, paleontologists have been piecing together how the mysterious predator Andrewsarchus is related to other mammals, like the extinct “hell pigs” and “wolves with hooves”

Paleontologists have found early examples of theropods, the group that would eventually include tyrannosaurs. But precisely how another group of dinosaurs, known as the bird-hipped ornithischians, evolved remains a major question in paleontology.
