Question

Which one of the following dinosaur fossils is a theropod?

• A. Kotasaurus
• B. Titanosaurus
• C. Rajasaurus
• D. Barapasaurus

Answer 1

The Correct Option is C

To solve the question of which dinosaur fossil among the options is a theropod, we need to understand the classification of dinosaurs and focus on the characteristics of the options provided. Dinosaurs are generally divided into two major groups based on hip structures: Saurischia and Ornithischia. One of the sub-groups of Saurischia is the Theropoda, which includes predominantly carnivorous dinosaurs.

Let's analyze each of the given options:

1. Kotasaurus: This dinosaur belongs to the group of Sauropodomorphs, which are typically large, long-necked, herbivorous dinosaurs. Kotasaurus does not classify as a theropod.
2. Titanosaurus: Another member of the Sauropodomorphs, belonging to a subgroup called Titanosauria. These are known for being among the largest land animals, and they are herbivorous, not theropods.
3. Rajasaurus: This dinosaur is indeed a theropod. Theropods are characterized by hollow bones and three-toed limbs. Rajasaurus was a carnivorous dinosaur found in the Indian subcontinent and belongs to the Abelisauridae family, part of the Theropoda clade.
4. Barapasaurus: Like Kotasaurus and Titanosaurus, Barapasaurus is a sauropod dinosaur, meaning it is also herbivorous and not a theropod.

Based on the classification and characteristics of each dinosaur, Rajasaurus is the correct answer as it is the only one among the options that belongs to the theropod group.
