Abstract
Platythyris is included in the Pygopidae because of the resemblance of its internal structures to that family, despite the great difference in external form. The genus occurs in strata of Barremian to Senonian age in Europe north and west of the Alpine line and probably originated in the Caucasian-Crimean region. Three new species are described:P. vendeensis (Cenomanian),P. cristobali (Turonian) andP. viaudi (Senonian).Terebratula squamosa Mantell (Cenomanian) is assigned toPlatythyris and redescribed.Terebratula disparilis D’Orbigny (Cenomanian) is described as a subspeciesP. squamosa disparilis.
Zusammenfassung
Platythyris Middlemiss 1959 ist aufgrund ihrer inneren Merkmale trotz des ganz anderen äußeren Habitus den Pygopidae zuzuordnen. Die Gattung kommt im europäischen Barrême und Senon außerhalb (nördlich und westlich) der Alpen vor und hat ihren Ursprung wahrscheinlich im Raum von Kaukasus und Krim. Die Platythyridinae lassen sich als unspezialisierte schelfbewohnende Verwandte der auf die Tethys spezialisierten Pygopinae deuten. Es werden drei neue Arten beschrieben:Platythyris vendeensis (Cenoman),P. cristobali (Turon) undP. viaudi (Senon).Terebratula squamosa Mantell (Cenoman) wird zuPlatythyris gestellt und neu beschrieben.Terebratula disparilis D’Orbigny (Cenoman) wird als UnterartP. squamosa disparilis aufgefaßt und beschrieben.
