D. Heterocoelus

Answer

To answer the question regarding the type of vertebrae in humans, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Human Vertebrae**:
- Humans have a total of 26 vertebrae in their spinal column. These vertebrae are categorized based on their shape and structural characteristics.

2. **Identify the Types of Vertebrae**:
- Vertebrae can be classified into different types based on their shape:
- **Amphiplatyan**: Flat on both the anterior (front) and posterior (back) sides.
- **Procelous**: Concave on the anterior side and convex on the posterior side.
- **Amphicelous**: Concave on both the anterior and posterior sides.
- **Heterocelous**: Different shapes on either side, which is not found in humans.

3. **Determine the Correct Type for Humans**:
- In humans, the vertebrae are primarily **amphiplatyan**, meaning they are flat on both ends. This is the defining characteristic that distinguishes them from the other types.

4. **Eliminate Incorrect Options**:
- **Procelous** is incorrect because it has a concave anterior and convex posterior.
- **Amphicelous** is incorrect because it has both sides concave.
- **Heterocelous** is also incorrect as it is not found in humans.

5. **Conclude the Answer**:
- Based on the above analysis, the correct type of vertebrae in humans is **amphiplatyan**.

### Final Answer:
The type of vertebrae in humans is **amphiplatyan**.
