Which one is flying reptiles among the following?

Options

A. Archaeopteryx
B. Pteranodon
C. Stegosaurus
D. Tyrannosaurus

Answer

To determine which one is a flying reptile among the options provided (Archaeopteryx, Pteranodon, Stegosaurus, or Tyrannosaurus), we can analyze each option step by step:

### Step 1: Analyze Archaeopteryx
- Archaeopteryx is known as the first bird and lived during the late Jurassic era.
- It had wings and is considered a transitional species between reptiles and birds.
- However, while it could glide, it is not classified strictly as a flying reptile in the same sense as Pteranodon.

**Hint:** Consider the characteristics that define a flying reptile.

### Step 2: Analyze Pteranodon
- Pteranodon lived during the late Cretaceous period and is classified as a pterosaur.
- It had very large wings that could extend up to about 7 feet, making it one of the largest flying reptiles.
- Pteranodon is indeed a flying reptile, known for its ability to soar through the skies.

**Hint:** Look for the size and wing structure that indicates true flying capability.

### Step 3: Analyze Stegosaurus
- Stegosaurus was a herbivorous dinosaur present during the late Jurassic era.
- It was characterized by its four legs and distinctive bony plates along its back.
- Stegosaurus did not have wings and was not capable of flight.

**Hint:** Identify the body structure that indicates a non-flying dinosaur.

### Step 4: Analyze Tyrannosaurus
- Tyrannosaurus rex, commonly known as T-rex, was one of the largest land predators.
- It walked on two legs and had no wings, making it incapable of flight.
- Like Stegosaurus, it is not a flying reptile.

**Hint:** Consider the limbs and body structure to determine flight capability.

### Conclusion
After analyzing all the options, the only flying reptile among the choices is **Pteranodon**. Therefore, the answer to the question is **option number 2: Pteranodon**.
