Eye socket changes amped up bite force in T rex and friends

WASHINGTON: Tyrannosaurus rex possessed awe-inspiring bite force, with the huge meat-eating dinosaur's bone-crunching chomp estimated to pack about 3,630kg of might - about equal to the weight of three small cars.

"High bite forces and loads during feeding need to be accommodated by the skull and lower jaw," said paleontologist Stephan Lautenschlager of the University of Birmingham in England, author of the research published in the journal Communications Biology. It turned out that once a theropod species attained a skull length of about one metre or more, the shape of its eye sockets had become elliptical or keyhole-shaped.
