Formula ∞ +5+ 1+5 +∞, with up to 32 transverse rows of teeth, rows of asplayed M-shape, lateral 5 is most anterior tooth; rachidian with trigonal base-plate, anterior shaft tapering to rounded tip, lacking cusp; innermost lateral large, its outer anterior margin broadly expanded, antero-medial corner with small irregularly shaped cusp, usually bluntly rounded; laterals 2–4 progressively smaller and less triangular, cusp of lateral 2 an oblique blunt ridge, cusp of lateral 4 small and bluntly rounded, that of lateral 3 of intermediate shape; lateral 5 much larger, its cusp with three robust trigonal denticles, anterior face of cusp base angular. Inner four marginals relatively stout with recurved nondenticulate cusps. Thereafter marginals progressively more slender, their recurved cusps with pectinate margins; cusps of outermost marginals less strongly recurved, broader and more spathulate. Latero-marginal structures not evident. In folded state, laterals 2–4 lie behind lateral 1 and central field is overlain by lateral 5 and marginals.
