homology notes

This structure (the hyomandibular), on ontogenic grounds alone, can be considered homologous with the amphibian and reptilian columella and the mammalian stapes.[well established][VHOG]



taxon notes

The stapes is homologous to the hyomandibula. In this ontology, we use the class 'hyomandibular cartilage' generally to include the future stapes, the future hyomandibular bone of teleosts and the unossified cartilage in sharks.
