Pseudotoma is an extinct genus of predatory sea snails, marine gastropod mollusks belonging to the family Turridae. [1]

Contents

First appearing 48.6 Ma and believed to go extinct 7.2 Ma. Specimens of Pseudotoma have been found in Austria, Denmark, Germany, The Netherlands, The UK, and The continental United States. The Pseudotoma lived during the Paleocene epoch of Denmark and Greenland, The Oligocene epoch of Mexico, and in the Pliocene epoch of Italy

Description

The ovate, fusiform, shell is short and stout. The spire is about the length of the aperture. The columella is straight, very short, axis impervious. The siphonal canal is very short and wide. The anal sulcus is wide, moderately deep, close to the suture. The spiral sculpture is feeble. The axial sculpture consists of moderately strong riblets. The operculum is wide, ovate, with apical nucleus. The type species is Pleurotoma intorta described by Brocchi in 1814. [2]
