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
,
