Pelvis

The pelvis is an anatomical structure found in humans (see human pelvis) or in animals. It contains a large compound bone structure at the base of the spine, which is connected with the legs or rear limbs. This bony structure is called the pelvis skeleton or bony pelvis, and consists of os coxa, sacrum and coccyx.

The synsacrum is a skeletal structure, mainly described in birds and dinosaurs.
