The presence of an anguloarticular is interpreted as a synapomorphy of the Clupeocephala (Patterson and Rosen, 1977; Arratia, 1999).[TAO]

Dermal and endochondral compound bone that results from the fusion of the dermal angular and the endochondral articular and forms the posterior part of the lower jaw. It articulates with the dentary anteriorly and with the retroarticular postero-medially. The anguloarticular is paired.[TAO], Endochondral ossification of the posterior articular part of Meckel's cartilage.[AAO]

TAO has a distinct class for articular - in fact we need (at least) 3 classes here - articular, anguloarticular and malleus, arranged into a single VHOG group

articular

uberon

operculo angulaire, angulare, dermarticulare, angulaire, goniale

According to this theory (Reichert-Gaupp theory), the mammalian stapes is derived from the reptilian columella, the incus from the quadrate and the malleus from the articular (...).[well established][VHOG]
