Radiolites squamosus
d'Orbigny- Swinburne and Noacco, text-fig.2
Material:
1 specimen
, both valves (no. 24082
BBU-MPS
)
.
Description: Small size shell, with right valve (RV) long conical,
40 mm
long and
20 mm
in diameter at the commissural plane (
Fig. 7
f-g). The ornamentation consists of dense growth lamellae (
Fig. 7f
). The radial bands are folds curved towards the commissure separated by a narrow interband with one fold (
Fig.
7g
). Left valve (LV) is highly convex, with central apex but much eroded (
Fig. 7f
).
Discussion and remarks: Because we found only
one specimen
, the shell of
Radiolites squamosus
was not been cut for study in cross-section. This species is also mentioned by
Lupu (1976)
from RoȘia Basin (Northen Apuseni Mountains).
Age and distribution: early - middle Santonian in
France
(
Toucas, 1907
); late Santonian- early Campanian in
Croatia
(
Polšak and Mamuzic, 1969
),
Romania
(
Lupu, 1976
),
Slovenia
(
Pleničar and Jurkovsek, 1999
), middle-late Campanian in Spain (
Floquet, 1991
) and early Maastricthian in east
Serbia
(
Milovanovic, 1935
).
