Textiliomurex Merle 2011

Genus Textiliomurex Merle, 2011 TYPE SPECIES. — Murex textiliosus Lamarck, 1803 by original designation. Middle Eocene: Paris basin, France and Hampshire Basin, England. COMMENTS ON THE GENUS Textiliomurex shares similarities with Pterynotus (s.s.) and Pterynotus (Pterymarchia) such as a scabrous surface, columellar denticles and a series of internal denticles including ID, D1 to D6. Textiliomurex does not display trivaricate axial sculpture and lacks intervarices, usually found in Pterynotus (s.s.). The number of varices on the last whorls of Textiliomurex is higher (9-11) than in Pterymarchia (3-5, see Houart 1995). As with Pterynotus, we cannot give a subfamilial placement to this genus. Merle et al. (2011: 127) included six species in the genus. Recently, Lozouet (2023) added (with some doubt) one species from the Chattian of the Aquitaine Basin (Textiliomurex? problematicus Lozouet, 2023), and we add a new species from the Lutetian of the Paris Basin herein.
