Calvezella Schlagintweit, 2020

SCHLAGINTWEIT, FELIX, 2020, Calvezella, A New Replacement Name For Aragonella Calvez, 1989 (Type-Species A. Marginata), A Forgotten Orbitolinid From The Albian Of Spain, Acta Palaeontologica Romaniae 16 (1), pp. 35-36 : 35

Genus Calvezella Schlagintweit , nomen novum pro Aragonella Calvez, 1989

Type-species Aragonella marginata Calvez, 1989

Etymology: Named in honour of Hervé Calvez, who first described the genus. The genus name is feminine.

Remarks: The detailed description provided by Calvez (1989) is considered as still valid. Also the comparisons with the taxa Heterocoskinolina Saint-Marc, 1978 , and Abrardia Neumann & Damotte, 1960 are justified. Calvez (1989, p. 520) considered Paracoskinolina pertenuis Foury, 1968 from the Barremian of France a possible representative of " Aragonella " lacking rafters in the marginal zone and therefore being more primitive than " A." marginata (with rafters). This species has correctly been removed from Paracoskinolina and taxonomically revised as Eopalorbitolina pertenuis (Foury) by Cherchi & Schroeder (2002).

Occurrences: The type-locality chosen by Calvez (1989) is the hermitage of Las Aras, Province of Aragon ( Fig. 1 a-b). In the outcropping Urgonian limestones (Urgo-Albien), Calvezella marginata is associated with other orbitolinids such as Simplorbitolina conulus Schroeder and S. manasi Ciry & Rat. This assemblage characterizes the uppermost early to middle Albian ( Schroeder and Neumann, 1985).

Apart from the original description, Calvezella marginata has been observed in wackestones associated with S. conulus from the Ramales Formation of the Solorzano section in Cantabria, south-east of the city of Santander ( Schlagintweit et al., 2017, Figs. 1 , 3), ( Fig. 1 c-d).
