| + | ==FORAMINIFERA FROM THE UPPER CRETACEOUS OF NORTHERN JAMES ROSS ISLAND (ANTARCTICA)== | ||
| + | |||
| + | <font size="2"> | ||
| + | During geological mapping of the northern James Ross Island a number of samples from Upper Cretaceous lithologies were gathered to test the presence of foraminifers as a possible tool for stratigraphic evaluation of Upper Cretaceous strata. Limited number of samples did not provide foraminiferal content large enough to give relevant information for biostratigraphic conclusions. Samples from older sediments of Whisky Bay and Kotick Point formations (Albian – Turonian) were either not fossiliferous or contained scarce specimens of agglutinated foraminifers. Foraminiferal assemblages from younger sediments of Hidden Lake and Santa Marta formations (Coniacian – Campanian) contained species with both agglutinated and calcareous types of tests. Many of studied marine sediments were barren of foraminifers, probably due to late diagenetic secondary decalcification. Taxonomy of low-diversified assemblages was carried out and a biostratigraphical and palaeobiogeographical significance discussed. | ||

| + | The praeglobotruncanid test appearance was iteratively developed in three genera/directional lineages during the late Albian-Santonian. A new genus/directional lineage, ''Bermudeziana'', and a new species, ''Fingeria praeglobotruncaniformis'' are described. A new system of species types is developed for the evolutionary classification, as a tool to describe the morphological changes within a lineage and compare the developments in lineages in which certain features were achieved independently | ||
