The neurocranium is not depressed; the vomeral tooth row is restricted to a small crest and the parasphenoid is straight in sagittal profile and thin.
It separates the neurocranium from the cervical spine, deep neck spaces and facial viscerocranium (i.
3); one pair of slender uroneurals; three epurals; a free parhypural; three thin supraneurals, generally straight; two supernumerary spines on first dorsal pterygiophore; no procumbent spines (spurs); thin Y-shaped basisphenoid, free from parasphenoid and prootics; neurocranium with frontal tabs similar to Vincentia Castelnau, 1872 (Fraser 1972: pl 31); supramaxilla absent; posttemporal smooth or with 1-3 small serrae on posterior margin; preopercle with 2-3 small, widely spaced serrae near angle, ridge smooth; infraorbitals smooth; infraorbital shelf present on third bone; ring of scleral cartilage, no ossification present; 7 branchiostegals; ceratohyal notched, suture smooth with epihyal; urohyal with short anterior process.

Analysis of cartilage in these embryos suggests that RA differentially affects the patterning of subpopulations of neural crest cells and the formation of specific cartilage elements, resulting in very different patterns of deletions in the neurocranium and the pharyngeal skeleton.
