Cyrtostropha
Taxonomy
Murchisonia (Cyrtostropha) was named by Donald (1902) [Sepkoski's age data: S Ldov-m S Ludl-l Sepkoski's reference number: 1197]. Its type is Pleurotoma coralli.
It was synonymized subjectively with Murchisonia by Knight et al. (1960); it was reranked as Cyrtostropha by Sepkoski (2002) and Wagner (2023).
It was assigned to Murchisonia by Donald (1902); to Archaeogastropoda by Sepkoski (2002); and to Murchisoniidae by Wagner (2023).
