Deinonychus and its dino relatives may not have used their wicked, curved claws to slash and disembowel their victims; instead, these fearsome hunters may have used these claws to pin and grasp their helpless prey. In new research, scientists observed the red-legged seriema (Cariama cristata), a South American predatory bird...

About 70 million years ago, titanosaurs the length of school buses stomped through what is now west central India to lay their eggs by a riverbank. While these long-necked sauropods and the river are long gone, many of their nests remain intact, full of fossilized dinosaur eggs that reveal clues...

An utterly bizarre dinosaur with claws so gigantic that their function has long remained a mystery couldn't use them to fight or fend off attackers because they were too flimsy, a new study has found. The theropod dinosaur, Therizinosaurus, lived in the Late Triassic and Cretaceous (220 million to 66...

Air sacs sandwiched inside the bones of the largest dinosaurs and pterosaurs to roam the Earth were so advantageous that these pockets might have evolved independently at least three times in different lineages, a new study finds. Researchers already knew that these ancient giants had air bubbles in their bones....

The longest-necked dinosaur on record was a Jurassic beast with a 49.5-foot-long (15.1 meters) neck, a new study finds. That's more than six times the length of a giraffe's neck and about 10 feet (3 m) longer than the length of a school bus. This long-necked sauropod, known as Mamenchisaurus...

The extremely rare discovery of an 80 million-year-old fossilized voice box that belonged to an armored dinosaur reveals that the ancient beast may have sounded more birdlike than experts previously thought, new research suggests. Pinacosaurus grangeri — a squat, armor-plated and club-tailed ankylosaur unearthed in Mongolia in 2005 — was...

Popular depictions of the superpredator Tyrannosaurus rex snarling to display its gigantic, knifelike teeth are scientifically inaccurate, new research suggests. Theropod dinosaurs — a group of bipedal, mostly meat-eating dinosaurs that included T. rex, Velociraptor and Spinosaurus — may instead have concealed their deadly chompers behind thin lips that kept...

Bird-like dinosaurs that lived up to 74 million years ago didn't hog nests; instead, these beaked dinosaurs shared communal nests where several female nestmates often laid more than 20 eggs together, which these feathery dinos then brooded to keep warm, new research suggests. Most dinosaurs are thought to have laid...

A beautiful crystal stored away in a mineral collection 135 years ago was harboring an even rarer treasure: The shell of a 67-million-year-old titanosaur egg. The encrusted egg originates from a volcanic plain in central India, prompting researchers to think that a lava flow smothered the nest shortly after the...

A nearly 100 million-year-old, exceptionally well-preserved sauropod skull discovered in Australia may show that dinosaurs trudged across Antarctica from South America to Australia, researchers have revealed. The near-complete sauropod skull belongs to a species called Diamantinasaurus matildae. Sauropods are known for their extremely long necks, with one dinosaur's neck stretching...

Apple TV+'s award-winning series Prehistory Planet will return in May, but for viewers itching to discover what the second season has in store, the official trailer is now out. Narrated by Sir David Attenborough, the five-episode event promises to transport viewers back to the age of dinosaurs with extraordinary visual...

The asteroid that wiped out the dinosaurs did not trigger a long-lasting impact winter, scientists have found — a discovery that raises new questions about what happened on Earth just after it hit. One spring day 66 million years ago, a 6-mile-wide (10 kilometers) asteroid smashed into the Yucatán Peninsula...

One of 2022’s biggest surprises for dinosaur fanatics was the cutting-edge Apple TV+ documentary series Prehistoric Planet. Now, season 2 is almost here, and we’ve got you covered with every new bit of info you need to know ahead of its debut, plus a complete guide on how to watch...

The fossilized remains of a truly gigantic ancient sea monster have been discovered by chance in an English museum, revealing one of the largest carnivores to ever stalk the seas. The four bones are vertebrae from an unknown species of Jurassic predator called a pliosaur and show that the dagger-toothed...

The total number of Tyrannosaurus rex to ever roam Earth has been recalculated by scientists, with new research revealing 1.7 billion of these dinosaur kings existed throughout our planet's history. In April 2021, a study published in the journal Science estimated that up to 2.5 billion T. rex individuals lived...
