The peculiar dental structure of Nigersaurus
The dental structure of Nigersaurus is one of its most defining features. Its jaws contained 500 teeth arranged in rows or columns, with 50 columns on each jaw. These teeth were not only numerous but also replaced rapidly, with new teeth growing to replace worn-out ones approximately every 14 days. This rapid tooth replacement ensured that Nigersaurus could maintain its grazing efficiency throughout its lifetime.
Each tooth in Nigersaurus' jaw was small, narrow, and closely packed, forming a continuous cutting edge that allowed it to shear through tough plant material. The teeth were also angled slightly forward, a feature that further enhanced its ability to graze on low-lying vegetation. This unique dental arrangement has led scientists to compare Nigersaurus' feeding style to that of a lawnmower, emphasizing its role as a specialized grazer.
Research into the dental structure of Nigersaurus has provided valuable insights into the dietary habits and ecological role of this dinosaur.
