| Summary: | LATE CRETACEOUS AND TERTIARY FOSSILS FROM GLACIOMARINE SEDIMENTS OF MELVILLE PENINSULA, KING GEORGE ISLAND (WEST ANTARCTICA) Summary Numerous well-preserved fossils have been found at the Melville Peninsula by the Polish Antarctic Expedition of the Polish Academy of Sciences in the austral summer 1980/81. The fossils come from a sequence of thin-bedded sandy-marly glaciomarine sediments about 200 m thick. The deposits also yield erratic boulders (dropstones) coming from the Antarctic continent. Specific lithological and paleontological features of these deposits made it possible to propose a new lithostratigraphic unit for West Antarctica - the Cape Melville Forniation (3). Marine microfossils recorded in the formation include planktonic assemblage of coccoliths: Corollithion achylosum (Stover), C. exiguum Stradner, Hayesites albiensis Manivit, Tetralithus gothicus Deflandre, Prediscosphaera cretacea (Arkhangęlsky), Vekshinella and Zygodiscus as well as diatoms (Coscinodiscus), chrysomonad cysts, silicoflagellates (Distephanus) and agglutinated and calcareous benthic foraminifera (Cyclammina, Pullenia and Uvigerina) (Figs. 4-5). Marine invertebrates are here represented by solitary, corals (Flabellum), bryozoans, bivalves (? Portlandia), gastropods (? Fusus), scaphopods, belemnites, polychaetes (Glycera, Ophryotrocha), ostracods, crabs (Majidae), asteroids and echinoids (? Isechinus and cidaroids) (Figs. 6-8), and marine vertebrates - by innumerous fish remains. Deposits yielding these fossils are strongly bioturbated. A marked predominance of benthic organisms and numerous traces of their life activities (Fig. 3) and occurrence of very numerous coprolites suggest sedimentation in a low-energy environment of shallow-shelf zone. The presence of erratic boulders in rocks of the Cape Melville Formation evidences continental glaciation (Melville Glaciation - 3). The boulders are usually about 50 cm in size but some of them approach 2 m in size (Figs. 2, 9). Limestone boulders were found to yield numerous ...
