Nigersaurus was a very specialised sauropod,‭ ‬evolved for feeding as a low browser.‭ ‬To accomplish this,‭ ‬the skull was shaped so that the jaws formed a very broad,‭ ‬flat edge across the front maximising the amount of vegetation gathered in a single bite.‭ ‬Inside these jaws were hundreds of teeth arranged in a single straight line near the edge of the mouth that would have been ideal for cropping very low vegetation with little effort.‭ ‬A further adaption is the structure of the inner ear that indicates that the head was usually carried in the down position so that the front of the mouth was always presented towards the ground where its choice food supply was.
