Question

Nodosaurid skulls ___________.

A. lacked horns at their posterior corners
B. were broad
C. had trenchant teeth
D. none of the above

Answer 1

The correct answer is option B, nodosaurid skulls were broad. They lacked horns at their posterior corners and had teeth adapted for a herbivorous diet, not trenchant teeth.

Step-by-step explanation:

The question is inquiring about the characteristics of nodosaurid skulls. Nodosaurids are a group of dinosaurs known for their heavily armored bodies and skull structure. They were part of the ankylosaur family, which were herbivorous dinosaurs from the Late Jurassic to the end of the Cretaceous period. When it comes to the options provided:

1. Nodosaurid skulls lacked horns at their posterior corners.
2. They indeed had broad skulls.
3. However, unlike carnivorous dinosaurs, which had trenchant, or sharp and effective, teeth, nodosaurids had small, leaf-shaped teeth adapted for a herbivorous diet.

Therefore, the correct answer to the question 'Nodosaurid skulls ___________.' would be option B, they were broad.
