Dinosaurs

Scientists have discovered a new crater in the seabed of the North Atlantic Ocean that seems to date to the end of the Cretaceous period. That suggests the extinction event that killed off the dinosaurs could have been triggered by multiple impacts.

Armored dinosaurs like Stegosaurus and Ankylosaurus were mostly big, bulky animals that walked on four legs, but paleontologists have now discovered a bizarre relative the size of a dog that strutted around on two legs.

The dinosaur king may yet retain its crown. Earlier this year a study proposed that the iconic Tyrannosaurus rex should be split into three distinct species, but a new analysis says there isn’t enough evidence for such a drastic shake-up.

It’s hard to find a cooler collectible than the skeleton of a long-dead predator. The latest to hit the auction block is a Gorgosaurus, a distant relative of T-rex, which will be offered for sale by Sotheby’s New York in its Natural History sale.

Paleontologists have described a new species of giant carnivorous dinosaur from a fairly complete skeleton in Patagonia. The discovery could help shed new light on the mystery of why such powerful predators had almost comically tiny arms.

In drawings or renderings of dinosaurs, we generally don't see the beasts sporting human-like belly buttons. The reptiles did have an equivalent to a navel, however, and scientists have recently discovered the first known fossilized example of one.

Dinosaurs sit at the crossroads between reptiles and birds, leading scientists to debate whether they were warm- or cold-blooded. A new study may have the answer for different dinosaurs by analyzing metabolic markers from their breath in their bones.

Paleontologists have discovered the largest raptor dinosaur ever found. The new species, known as Maip macrothorax, was a super predator of the megaraptor family that stalked the forests of Argentina some 70 million years ago.

After being declared the first known swimming dinosaur in 2020, Spinosaurus was subsequently suspected of being a shore-wader. A new analysis of its bones, however, has swung the needle back towards the concept of it going underwater to hunt its prey.

The most discerning of dinosaur-obsessed kids always knew that Triceratops was the coolest. And now, the coolest specimen of this coolest dinosaur has just gone on public display for the first time – Horridus, the world's most complete Triceratops.

Tyrannosaurus rex is one of the few dinosaurs that has its full scientific name in wide use. But now a new analysis of known fossils reveals that T-rex might be three separate species, including the newly proposed T-imperator and the T-regina.

For some time now, it has been known that modern birds are direct descendants of the dinosaurs. Now a fresh analysis of a fossilized dinosaur embryo has brought that prehistoric relationship into a new and particularly sharp focus.
