    1. Introduction. Pterotheca Salter, is a readily identifiable bellerophontoid gastropod with a low ovate to sub-rectangular shell and a raised median carina. Despite its bellerophontoid affinity and marked incurved apex it lacks true coiling of the shell (Ulrich and Scofield, , Reed, , Knight, ).Internally, the shell contains a triangular septum at the posterior end, and this Author: Jan Ove R. Ebbestad, Juan Carlos Gutiérrez-Marco. Two occurrences of Middle Ordovician opercula belonging to the gastropod Maclurites are described, one from the Taimyr Peninsula, Siberia, and one from the Kuskokwim Mountains, Alaska. The Taimyr opercula are the first to be described from Russia. Like other opercula of the genus, these thick specimens have a relatively massive prong on the interior to which the Cited by:

Since the slit is the site for the exhalant current, the most plausible hypothesis is that the "horns" were indeed. The Bouchet & Rocroi system of gastropod taxonomy was laid out in a book-length paper entitled "Classification and Nomenclator of Gastropod Families", which was published in the journal Malacologia and which was written in collaboration with J.

Frýda, B. Hausdorf, W. Ponder, Á. Valdés and A. Warén. Gastropods are also sometimes known in older books as "Univalves", because they possess a single shell (in contrast to bivalves with two, and chitons with eight).

The shell varies greatly from high- and low- spired helical coiled (snail-like) shells, planispirals (coiled in one plane) found in some Paleozoic marine and modern freshwater types.
