Using the computer images, the team could build a 3D model of the jaw, to reveal how the tooth spiral worked.

"As the mouth closes, the teeth spin backwards... so they slash through the meat that they are biting into," Dr Tapanila told BBC Nature.

"The teeth themselves are very narrow: nice long, pointy, triangular teeth with serrations like a steak knife.
"As the jaw is closing and the teeth are spinning past whatever it's eating, it's making a very nice clean cut."
