Abstract
The findings of dasycladacea Salpingoporella milovanovici in Cenomanian of
Dinaridic and Campania-Lucania Carbonate Platforms suggest that this little
known species has had significant geographic distribution within Periadriatic Car-
bonate Platforms (Adriatic, Dinaric, Campania-Lucania; type region: Mirdita Zone,
Intemides).
Dasycladacea Salpingoporella milovanovici is described from the Cenomanian li-
mestone of Paštrik mountain (Mirdita Zone) (Radoičić, 1978). In addition to seve-
ral localities on the type region, the species was also found in Cenomanian rocks of
Vodice in Dalmatia (Adriatic Carbonate Platform). Limestones with Salpingoporella
milovanovici on Mt Paštrik bear an assemblage of foraminifers with Pseudorhipidio-
nina casertana (De Castro), Pseudorhapydionina laurinensis (De Castro). Broeckinella
(Pastrikella) balcanica Cherchi, Radoičić & Schroeder, Nezzazata gyra (Smout), Tro-
chospira avnimelechi Hamaoui & Saint-Marc, Murgeina apula (Luperto-Sinni) and
Nezzazatinella spp.
The Apennines: Campania-Lucania Carbonate Platform
The outcropping terrains in Monti di Lauria assigned to Campania-Lucania Car-
bonate Platform. The sedimentary rocks sequence in this region consists primarily of
Lower and Upper Cretaceous limestones and dolomites and less extensive Tertiary
deposits. Salpingoporella milovanovici was found in Cenomanian limestone in two
localities of Lauria area: Monte Messina and Serra Vaddellona.

A Lower Cenomanian dolomite sequence by the road on Monte Messina eastern
slopes includes only one bed of foraminiferal limestone (wackeston - grainstone). In
this limestone foraminiferal association with frequent Nummoloculina heimi Bonet
and other miliolids, rare Biconava bentori Hamaoui & Saint-Marc, Trochospira cf.
avnimelechi Hamaoui & Saint-Marc, Nezzazatinella spp., Broeckinella sp. and Cune-
olina sp. have been observed. The few dasyclads are represent with Salpingoporella
milovanovici and Cylindroporella cf. C. parva Radoičić.
The dolomite sequence at Serra Vaddellona western slopes includes several beds of
limestone with radiolitids. Salpingoporella milovanovici was recognized in one of the
beds with scarce foraminiferal association - Pseudorhapydionina dubia (De Castro),
Pseudorhapydionina cf. P. laurinensis, Biconcava bentori, Pyrgo globulosa Tronchetti
and other miliolids.
The Dinari des: Dinaric Carbonate Platform
Cenomanian deposits near Nikšić (Montenegro) consist of sporadic occurrences of
limestones with radiolitids and the prevailingly scarce microfossil content, in additi-
on to beds bearing Chondrodonta joannae Choffat and/or other oysters. Scarce fora-
miniferal assemblage is formed by Pseudorhapydionina dubia, Pseudorhapydionina
laurinensis, Cuneolina, Dicyclina, Nezzazatinella and different miliolids. Algae, He-
teroporella lepina Praturlon, Neomeris sp. and Salpingoporella milovanovici are fe-
wer. Localities: west of the Krupac dam and north of Gomje Polje.
Salpingoporella milovanovici has been recognized in similar Cenomanian limesto-
nes of Popovo Polje area (Hercegovina).
Observation on Salpingoporella milovanovici
Few specimens of slightly larger thallus than those in the type region are noted in
limestones of Serra Vaddellona and Nikšić area. According to all of the available data,
the measurements od Salpingoporella milovanovici are the following:
Outer diameter of calcareous tubes	0.070 - 0.320 mm
Diameter of canal	0.035 - 0.190 mm
Distance between whorls	0.040 - 0.080 mm
Number of branches in the whorl	9-16
Calcareous envelope around proximal part of the branches forms a compact tube.
Distally, between two successive verticils, the envelope tapers into thin laminae
which reach the subcortical part of the thallus and are mainly either partly preserved
or barely discernible. The envelope is sometimes reduced to a narrow part around the
axis - the sections of such tube resemble those of Salpingoporella annulata similarly
preserved.
The contour of axial cavity has not always been visible, particularly when these
fossils (as in Serra Vaddellona limestones) present calcite moulds of the original en-
velope. The minute poorly preserved Salpingoporella milovanovici are often difficult
to recognize as dasycladacean and are easily overlooked. The likely reason is the ab-
sence of registered findings since the introduction of the species.

The findings reported in this note suggest a significant geographic distribution of
Cenomanian Salpingoporella milovanovici, especially within the Periadriatic Carbo-
nate Platforms. The favourable habitat of Salpingoporella milovanovici were protec-
ted platform areas.
