Teeth with multicuspid cladodont crown; central cusp twice as high and three times more broad than the lateral and intermediate cusps; pair of high accessory cusplets placed outside the lateral cusps; two rows of numerous high and small accessory cusplets placed labially; intermediate cusps and cusplets differently directed and incurved; labial cristae on the central cusp extended and prominent at the base; sub-lenticular base very elongated mesio-distally; ridge-like apical button considerably elongated, placed close to the lingual rim; shelf-like wide labio-basal projection; dense network of vascular canals occupying the entire tooth base.
Afterwards, the pEK induces the sEK in multicuspid teeth.
Depth 2.8 and head 3.66 in SL (two largest specimens); preventral area flattened, with pelvic spines reaching to half pectoral fin length, under skin; trunk scales 7/38/5; anal fin iii,20; anterior part of head Deuterodon-like, with multicuspid teeth, but the snout not very elongate, shorter than eye diameter, equal to the maxilla in projection; maxilla reaching to vertical through anterior margin of eye; premaxilla 2/5, broadest tooth with up to 9 cusps; maxilla with 3 multicuspid teeth; mandible with 67 teeth, anteriormost with 7-9 cusps; a humeral spot, a longitudinal band from dorsal fin to end of middle caudal fin rays, enlarged on peduncle.
Recently, it has been demonstrated that a second set of signaling centres, known as secondary enamel knots, function to determine the multicuspid pattern of molar crowns [Jernvall and Jung, 2000; Miletich and Sharpe, 2003].
The angles between the lateral cusps range from 40[degrees] to 60[degrees], the largest angle occurring in the bicuspid and multicuspid teeth; the lateral cusps of tricuspid crowns diverge at an angle of about 50[degrees].
2); upper teeth multicuspid, first row with one to two lateral cusplets on either side of single, pointed median cusp; teeth in lower jaw unicuspid, in single series, not erect, overlapping, with blade-like edge; upper tooth counts numbering 27 (25-30); lower tooth counts numbering 42 (33-36).
