Verified step by step guidance

1. Step 1: Begin by understanding the problem, which is asking about a dinosaur known for having approximately 500 teeth. This requires knowledge of paleontology and specific dinosaur characteristics.
2. Step 2: Review the options provided: Triceratops, Tyrannosaurus rex, Stegosaurus, and Nigersaurus. Consider the anatomical features of each dinosaur, particularly their dental structures.
3. Step 3: Recall that Nigersaurus is a sauropod dinosaur known for its unique dental arrangement. It had a wide, flat mouth and rows of small, closely packed teeth designed for grazing on vegetation.
4. Step 4: Compare this information with the other options. Triceratops had beak-like structures for cutting plants, Tyrannosaurus rex had large, sharp teeth for tearing meat, and Stegosaurus had small teeth for chewing plants, none of which match the description of 500 teeth.
5. Step 5: Conclude that Nigersaurus is the correct answer based on its distinctive dental structure and the approximate number of teeth it possessed.
