Apical view of a polished cross section of the right (lower) valve of Hippurites nabresinensis from the St. Bartholomä-Formation of the Gosau basin of Kainach - St. Bartholomä in western Styria, Austria. This species has no L-pillar, the P1-pillar is at ca. 3:00, the P2-pillar at ca. 5:00. The hump at ca. 8:00 is a growth anomaly. At ca. 11:00 and 1:00, the position of both teeth sockets is visible (a hypothetical L-pillar would be between them, see the specimen of H. colliciatus), at ca. 2:00 the position of the posterior muscle. At the upper left, it is intergrown with the fragment of another individual of the same (?) species.
For specimens like this, the name H. heritschi was also in use.
The specimen is from a large mound of stones, which were removed from the fields during many, many decades. This mound located in the southwerstern part of Kalchberg, southwest of St. Bartholomä (Point 36 in my own documentation).
