A new study suggests features in the prehistoric creature’s mouth helped it eat more efficiently, giving the species the energy needed to go airborne

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.

Paleontologists have identified thousands of animal species that lived soon after the Cambrian explosion ended

The small dinosaur Patagonykus—one of an odd-looking group called alvarezsaurs—puzzled experts with its stout claws and bird-like bones.

Small, Stubby-Armed Dinosaurs Have Confounded Paleontologists. Are Answers Finally Within Reach?

Recent discoveries about an alvarezsaur called Manipulonyx have drawn renewed attention to this group of bird-like, clawed creatures and the mysteries around their anatomy and behavior

Paleontologists removed roughly 3,000 pounds of rocks and fossils from the site between mid-September and mid-October 2025.

The extinct animals may have bounced from scary situations, such as coming face to face with hungry predators

Shovel-tusked elephants like Amebelodon were discovered nearly a century ago, and paleontologists have learned more about their anatomy and behavior with time. This 1932 illustration was later found to be inaccurate, as Amebelodon actually had a longer and narrower trunk.

Strange, Shovel-Tusked Elephants Puzzled Paleontologists, Until Experts Took a Closer Look at Their Teeth

The animals’ extended lower jaws were seemingly made for scooping, but research over the past few decades has found they could do a lot more than initially expected
