Tongue-tied: T rex couldn't stick out its tongue

Researchers say many dinosaurs' tongues were anchored to the floors of their mouths and unable to waggle

The fearsome creatures of Jurassic World might chase you, kill you and rip you limb from limb, but there is one thing a T rex couldn't do: stick out its tongue.

While Hollywood depictions of dinosaurs often show the creatures open-mouthed with tongues waving, researchers have discovered that many of them were probably tongue-tied, their tongues firmly anchored to the floors of their mouths and unable to waggle around.
