A skull of a giant crocodile that lived 95 million years ago has been unearthed in Morocco.
Known as Aegisuchus witmeri, the crocodile had a large armoured head and bony shield that it would have used as a type of trap to catch fish. "It is possible that it lay in wait until an unsuspecting fish swam in front of it," said researcher Nick Gardner. "Then, if it was close enough, Shieldcroc simply opened its mouth and ate the fish without a struggle, eliminating the need for strong jaws."
The shield may have been used to attract mates and intimidate enemies, or as a thermo-regulator to control head temperature. Dr Casey Holliday, from the University of Missouri, US, said: 'Today’s crocodiles live in deltas and estuaries, the environments put under the most stress from human activity. '
