Description(s)

Diagnosis. - Jaw elongate, both margins convex. The anterior part of inner margin denticulate, with hook long and upturned. Outer margin turning posteriorly into a small process. Posterior margin bipartite. Pulp cavity open. Description. - Hook long, upturned. Outer margin undulate, with a depression appearing just behind the base of hook and another near the posterior end of margin, where it turns into a small process. Inner margin convex, its posterior sector edentate. The second denticle long, situated near hook facing anteriorly and bent upwards. The successive denticies, also long, are bent and gradually diminishing posteriorly. Posterior margin bipartite: its outer, longer sector running obliquely anteriorly, its inner sector straight. The MIl and MIlI are similar to other Triassic species of the genus Kielanoprion (cf. Zawdzka 1971: "Leodicites", Euncites sp., and "gen. et spec. indet. A"). Occurrence. - Lower Muschelkalk (Pelsonian) at Wierchlesie (Opole Silesia).
