Triassurella Nützel and Geiger, 2006


Genus Triassurella Nützel and Geiger, 2006  

Type species: Triassurella carnica Nützel and Geiger, 2006   (by original designation), from the Late Triassic Cassian Formation in the Italian Alps.

Remarks: Although Nützel and Geiger (2006, p. 281) noted that the asymmetrical limpet shape with strong expansion rate as seen in Triassurella   , Sutilizona   and Temnocinclis   is exclusively found in deep-sea families today, they placed Triassurella   in the Scissurellidae   . It is transferred here to the Sutilizonidae   based on the strong similarities between Triassurella goederti   n. sp. and Sutilizona theca McLean, 1989   .
