description
DESCRIPTION The bone is ornamented by thin ridges. The insertions for the Baudelot’s ligament are ovoid and lateroventrally located.
discussion
REMARKS The basioccipital supporting the Baudelot’s ligament insertions is a feature encountered in many beryciforms and percomorphs (Johnson & Patterson 1993; Patterson & Johnson 1995). The bone shows superficial resemblances in the ornamentation with those of serranids and latids. The insertions for the Baudelot’s ligament are located more laterally in latids, and lateroventrally in serranids or Semlikiichthys Otero & Gayet, 1999 (Otero et al. 2008), like in Bouj- 370. The size, vermiculated ornamentation and circular articulation for the first vertebrae suggest that the basioccipital and the isolated centra described above belong to the same taxon.
