Acetate Peel and Other Biotic Data from Selected Antarctic Permian Beds

Abstract

Introduction Published data on fossil biotic elements from the Antarctic Paleotoic, particularly the Permian, are most sparse. Additions of any kind, for example, reports on spoor, fragmentary fossils artifacts among others, can help to expand available knowledge. The present study a spin-of3 of a larger research project, supplements previous reports on the same theme (Tasch, 1968a. 19685). Collections during austral summer 1966-67 included samples from fossiliferous and ncyn-fossiliferous l)eds. Of these, samples studied by the acetate peel technique incIuded in this report came from the following localities and beds: Ohio Range beds 0-17, 0^19 (for details see Tasch and Gaffordn 1968; Tasch, 1970); Sentinel Mts.-bed S-14 Whiteout Nunatak near the contact of the Polarstar Formation and the Whiteout Conglomerate. Standard acetate peel techniques were used (Stewart and Taylor, 1965) . In addition to acetate peel stlldies, an object attached to a leaiid conchostracan valve from the Ohio Range Levia Zone (Bed 0-21.8), not previously reported in the literature is figured and described.
