Discussion.
The single specimen from Santa Maria is too poorly preserved to offer a description.
Orania fusulus
(
Brocchi, 1814
)
, from the Upper Miocene to present-day Mediterranean and eastern Atlantic from
Portugal
to
Angola
, including the oceanic islands of Azores, Madeira, and Canary Islands, is slenderer, with a longer siphonal canal.
Orania turrita
(
Borson, 1821
)
has a similarly short siphonal canal, but is squatter, broader with a more scalate spire. In profile, the Azorean specimen is most like
O. bellardiana
(
Foresti, 1884
)
from the Lower Pliocene of
Italy
. That species had not been refigured since its original description until recently (
Ceregato
et al
. 2010
: pl. 1, figs. 10- 12;
Brunetti & Cresti 2018
: fig. 267). Better preserved material would be needed to confirm this identification.
Distribution.
Lower Pliocene: Atlantic, Santa Maria Island,
Azores
(this paper).
