Summary: | Berane Basin in Montenegro has been known for rich paleoflora of diverse
geological ages. The remains of paleovegetation of various ages were
preserved by the lake occurring in this area from Late Oligocene to Early
Pliocene. Therefore, the shifts in vegetation during the Miocene period may
be easily followed by studying the paleofloras collected at the Berane
Basin. The first and only known remains of aquatic (floating) plants were
collected in 1995 at the locality Rosulje (Berane Basin) in the Early
Miocene sediments. According to the morphoanatomical characteristics of
leaves such as shape of lamina, veins, venation, presence of central disk or
position of petiola, the specimens were identified as Nelumbo protospeciosa
SAP., a widely distributed form during the Tertiary of Eurasia. No other
plants or accompanying vegetation were recorded at the Rosulje site, so
presence of Nelumbo protospeciosa was insufficient for determining the
habitat, vegetation or climate during its existence. Therefore the
paleoenvironmental reconstruction also included analysis of the already
published Early Miocene flora from the locality Luge-Haremi (Berane Basin)
and eco-climatic characteristics of recent Nelumbo species. At last was
concluded that Nelumbo, which had leaves at least 30 cm in diameter, used to
inhabit open, well-insolated sites, probably under the influence of the
subtropical/Mediterranean-type climate. |
