development notes

The cartilaginous parts of the neurocranium undergo endochondral ossification in most species; ossification has been lost in cartilaginous fishes, but the cartilaginous condition of the skull of lampreys is considered to be primitive (Kardong, 1995)[PMID:11523816]. The neurocranium arises from paraxial mesoderm in the head (first five somites and the unsegmented somitomeres rostral to the first somite) and from ectoderm via the neural crest. In Chondrichthyes and other cartilaginous vertebrates this portion of the cranium does not ossify; it is not replaced via endochondral ossification[WP].
