A fused bone consisting of the ilium, ischium and and pubis. Together with the sacrum and coccyx, it comprises the pelvis. [WP,modified].
currently this class is restricted to exclude the teleost bone as the definition mentions ilium, ischium and pubis. In future we may add a grouping class for girdle bones that supports the appendage
in FMA this is a paired structure. NCITA has 'pelvic bone' but this is the *superclass* of ilium/ischium/pubis. The MA class 'pelvis bone' is actually a superclass of 'pelvic girdle bone' and caudal/sacral vertebra.
bone of pelvic girdle
The hip/pelvic bone/basipterygium first appears in fishes, where it consists of a simple, usually triangular bone, to which the pelvic fin articulates. The hip bones on each side usually connect with each other at the forward end, and are even solidly fused in lungfishes and sharks, but they never attach to the vertebral column
