Comment:
[taxon-note] "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" xsd:string {source="WP"}
