Extinction

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 previously unknown extinct tortoise was revealed in an investigation on these giants' evolutionary history.

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.

A female Tasmanian tiger that died in 1936, not a male named Benjamin, was actually the last surviving member of this extinct species. The female's remains had been hidden in museum storage.

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