A fossil of a Diegoaelurus jawbone was recovered from a construction site in Oceanside, California.

Paleontologists Uncover the Oldest Sabertoothed Predator

Fossil jaw shows earliest evidence of a specialized carnivore with scimitar-shaped fangs

Researchers excavated fossils from a site in Turkey that helped them fill in some of the history of a previously unknown continent called Balkanatolia. 

Fossils Help Scientists Identify a ‘Lost’ Continent

Millions of years ago, a giant island called Balkanatolia shifted and connected Asia to Europe, allowing animals to migrate

Authors of the new study say SUE the T. rex is actually a T. imperator, or tyrant lizard emperor. 

Why a New T. Rex Study Is Riling Up the Paleontology World

Established scientists are casting serious doubts on new research suggesting that the infamous, ferocious dinosaur is actually three different species

Nick Pyenson, the Smithsonian Institution’s curator of fossil marine mammals, compares the skeletons of ancient whales to the life-sized model of a North Atlantic right whale displayed at the National Museum of Natural History in Washington, DC. Whales have been evolving for more than 50 million years, and long before becoming ocean-dwelling giants, the earliest cetaceans walked on land. 

This Cliff Face Is Packed With Fossilized Whale Remains

An exposed prehistoric seafloor is a hotspot for relics, and now an international team is helping unravel their mysteries

Why Smuggled Fossils Are Hurting Paleontology

Parachute science and lingering colonialism in fossil studies have negatively impacted the discipline

More than 200 preserved footprints trek across the canyon's limestone surface and give clues about what life was like millions of years ago.

Construction Trucks May Have Damaged 112-Million-Year-Old Dinosaur Tracks at Mill Canyon in Utah

Nearly 30 percent of the site’s irreplaceable paleontological resources may have been impacted

A restoration of the extinct whale Phiomicetus, named by paleontologists earlier this year, preying upon a sawfish.

Whales Once Walked Along the Coasts of North America

Increasing fossil finds are helping researchers understand how such early whales made their way to the continent

Dinosaur Embryos Tucked Themselves in Just Like Birds

A stunning fossil egg has allowed paleontologists to find new clues about a dinosaur’s early development

In the mountains of southwestern Nevada, the dark fossilized remnants of extinct archaeocyath reefs dot the tops of the hills. Millions of years ago, these peaks were at the bottom of the sea.

Fossils From One of the World’s First Reefs Can Be Found on Mountains in Nevada

Archaeocyaths were the original reef builders, and one of the best places to see them is in the desert

The carnivorous theropods may have evolved a quick pace and sharp agility in order to capture prey.

These Three-Toed, Carnivorous Dinosaurs Ran as Fast as Usain Bolt

Two tracks of footprints reveal that theropods could reach speeds of nearly 28 miles per hour, providing insights on their behavior

Scientists previously hypothesized that Quetzalcoatlus took off by running and flapping its wings or pushing off its wingtips. 

This Giraffe-Sized Reptile Was the Largest Flying Creature to Ever Live

The pterosaur likely launched itself about eight feet off the ground before flapping away, solving the mystery of how these creatures could even fly at all

The footprints from site A (left) look similar to those excavated from site G (right), but they are much wider. 

A Set of Ancient Footprints May Have Belonged to an Unknown Human Ancestor

The prints were originally attributed to bears, but further analysis reveals that they don’t match bears—or any known human ancestors either

A Canyonlands park ranger stumbled across the fossil and reported it to the park about a year ago.

A 300-Million-Year-Old Fossil Discovered in Utah Could Be a New Species

Fossilized remains of aquatic creatures are commonly found in Canyonlands National Park, but discovering a land-dwelling vertebrate is incredibly rare

Mosasaurus was among the largest and last of the sea-dwelling mosasaurs.

Giant Sea Lizards Ruled the Waves While T. Rex Roamed on Land

A new fossil discovery shows marine reptiles called mosasaurs lived up until the asteroid impact that killed non-avian dinosaurs

Each nest was found with eight to 30 eggs and in a relatively small area, suggesting that Mussaurus patagonicus raised its young in a communal breeding ground

Paleontologists Unearth the Oldest Evidence of Herd Behavior in Dinosaurs

Fossils found in an ancient nesting ground reveals that herd mentality is almost 200 million years old
