Caturoidea indet.

Fig. 2A–C .

Material.—Three partial crowns of isolated teeth (ZPAL P. 16/O-B/FT1–FT3) from Upper Jurassic Kcynia Formation, Corbulomima Limestone (Unit III), Owadów-Brzezinki, Poland.

Description.— Loose teeth: the crowns of teeth, found loosely in the sedimentary rocks of Kcynia Formation. These conical-shaped teeth are slightly mesiodistally compressed with carinae placed along the mesial and distal planes of the crown. The T1 and T2 teeth consist of the apical and mid-crown section of the teeth, while the T3 tooth consists of the mid-crown section, with part of the acrodin cap preserved ( Fig. 2A–C ).

Remarks.—Carinae present along the mesial and distal planes of acrodin tooth cap.
