Fossils

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.

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.

Although it's not a hard and fast rule, marine animals that live in cold climates tend to grow larger than their warm-water counterparts. According to a new study, such may have true for everyone's favorite prehistoric shark, the megalodon.

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.

In most depictions of the extinct megalodon shark, it looks pretty much like a super-sized version of its modern relative, the great white. According to a new study, however, it may actually have been considerably less similar in appearance.

Scientists have discovered fossils of a new species of aquatic reptile that may be the first giant animal that ever lived on Earth. Cymbospondylus youngorum is a new type of ichthyosaur dating back to the early stages of the Age of Dinosaurs.

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.

A newly discovered fossil may change what we know about an ancient human relative. Vertebrae from the lower back of an Australopithecus sediba reveal it was surprisingly well adapted to walking upright like a human, while also climbing like an ape.

Tardigrades are notoriously hardy microscopic creatures, but one thing they’re not good at is fossilizing. Now an exceptionally well-preserved, “once-in-a-generation” tardigrade fossil has been found in amber, and assigned to a new species and genus.

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.

Fresh analysis of 54-million-year-old fossils has revealed the oldest known example of cavities among mammals, with prehistoric primates by the name of Microsyops latidens found to suffer from them with increasing regularity.
