Dinosaurs

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.

Teeth, claws and horns – the ancient arsenal of dinosaur warfare was varied, and now a brand new weapon has been added to the collection. Paleontologists have discovered a new type of ankylosaur with a tail like a battle axe.

Paleontologists have isolated cartilage cells from an exceptionally well-preserved dinosaur fossil. They still contain traces of biomolecules, and the scientists were even able to tell which stage of the natural cycle specific cells were in at death.

Your chance to own one of the most iconic dinosaurs is about to come up – provided you have a spare few million and an empty ballroom on hand. The largest known specimen of Triceratops, nicknamed “Big John,” will go up for auction in October.

Paleontologists have discovered the largest known flying reptile that ever took to the Australian skies. Named Thapunngaka shawi, this “fearsome dragon” sported a 7-m (23-ft) wingspan and a jaw full of awful jagged teeth.

About 66 million years ago, a gigantic object crashed into the Earth, triggering a mass extinction that took out the dinosaurs. Now, scientists say they’ve traced the culprit back to its point of origin, identifying it as a “dark primitive asteroid.”

Around 66 million years ago, a gigantic asteroid smashed into the Earth and ended the reign of the dinosaurs. Now, researchers have discovered direct evidence of this cataclysm – fossilized “megaripples” from the tsunamis that immediately followed.
