Modern birds, along with certain snakes and fishes, have skulls whose jaws and palates are not firmly fixed in place.

Scientists suggest that bigger brains in bird ancestors led to more flexible skulls, playing a key role in their evolution.

Rough patches and flanges on bone can be used to reconstruct the positions of muscles, cartilage and ligaments. Studying the scratches and wear patterns on teeth reveals vital information on diet and ...
