|Nigersaurus taqueti life reconstruction by Christopher DiPiazza|
Nigersaurus had a unique skull in that its mouth was wide and flat. The skull actually resembles a vacuum cleaner head to be honest (if you google image search "vacuum cleaner head" and scroll down a bit, a picture of Nigersaurus actually will be one of the results. No joke go try it). Inside the mouth were hundreds (six hundred to be exact) of tiny chisel-shaped teeth perfect for clipping low plants which it ate. Like sharks, whenever one of Nigersaurus' teeth broke off or got worn down, a new one was right underneath ready to take its place. Nigersaurus had the most teeth of any sauropod known to date.

Nigersaurus had a relatively short neck for a sauropod. Because of this, combined with the fact that its skull would have been naturally held facing the ground, suggests it specialized in eating low growing plants rather than foliage off trees like some of its longer-necked relatives.
