An example of an amphiarthrotic joint is indeed the spinal vertebrae. Amphiarthrotic joints are characterized by their slight mobility, allowing for limited movement between the bones they connect. In the case of the spinal vertebrae, these joints are connected by intervertebral discs and ligaments, which permit a small degree of flexibility and movement. This slight mobility is essential for functions such as bending and twisting of the spine while still providing structural support.

The other choices represent different types of joints. Sutures in the skull are classified as synarthrotic joints, which are immovable. The shoulder and hip joints are examples of diarthrotic joints, which are freely movable and allow a wide range of motion. Thus, spinal vertebrae serve as an appropriate example of amphiarthrotic joints due to their function and structure.
