Dinosaurs

A fossilized ankylosaur voice box reveals that these beasts may have sported a far more sophisticated vocal range than scientists originally thought.

By comparing the few known bones of the sauropod Mamenchisaurus sinocanadorum with its relatives, experts have extrapolated its tremendous neck length.

Some of the oldest dinosaurs didn't have hollow bones, suggesting that skeletal air sacs evolved independently in three lineages: long-necked sauropodomorphs, meat-eating theropods and pterosaurs.

Scientists have confirmed that Therizinosaurus, the scythe-clawed dinosaur from Jurassic World, couldn't have used its 'useless' gigantic claws to fight because they were too flimsy.

The discovery of a tightly packed nesting ground from the Cretaceous period in India suggests that titanosaurs laid eggs and left their offspring behind.

Unlike their portrayal in Jurassic Park, curved-clawed dinos may have used their sharp appendages to pin and grasp, not slash.

A 120 million-year-old bird fossil from China has some rather unusual dinosaur-like features in its otherwise standard avian skeleton, including a weirdly T. rex-like skull.

Birdlike dinosaur "was not a picky eater," as evidenced by a rodent's foot found in its fossilized remains.

Researchers analyzed the teeth of the earliest dinosaurs to determine what they ate.

New research contradicts the claim that diplodocids could whip their tails at supersonic speeds. Instead, it was a (still impressive) 62 mph.
