Remarks:
Test diameter is mostly between
1.6 mm
and 2.0 mm (maximum
2.2 mm
), thickness is
0.3 mm
to
0.5 mm
. The tiny proloculus observed in some forms has a diameter from
0.06 mm
to
0.07 mm
(
Fig. 6d
). Adult specimens consist of up to 15 planispirally-involute coiled whorls. The original material of Rahaghi was deriving from two localities in the Zagros Zone belonging to the so-called Lopha Limestone Member of the Gurpi Formation and assigned to the upper Campanian (
Wynd, 1965
; Hashmie et al., 2020).
P. hamaouii
is intermediate in size between the smaller
P. hekimhanensis
from the late Campanian?-Maastrichtian of
Turkey
(
Görmüş, 1999
) and the larger type-species
P. striata
from the Maastrichtian of
Qatar
(
Henson, 1948
). The specimens from
Iran
have been observed in the lower part of the Tarbur Formation in bioclastic packstones together with siderolitids, and
Omphalocyclus
(
Fig. 6a
). In southern
Turkey
it is recorded as
P. hekimhanensis
by Solak et al. (2019, fig. 9) from strata assigned to the lower Maastrichtian, namely an “
Orbitoides
,
Omphalocyclus
,
Siderolites
assemblage zone”.
