Triassic and Early Jurassic fossil floras from North Victoria Land, Antarctic

Basic data for this project

Description

While other regions of the Antarctic have yielded reasonably well-preserved Mesozoic plant fossil deposits, hardly any fossil floras were known from coeval strata of North Victoria Land. During the IX. German Antarctic North Victoria Land Expedition, plant material from a dozen newly discovered fossil localities of Triassic and Jurassic age has been collected. These floras are of special interest, because compressions yield excellently preserved cuticles and also anatomically preserved material has been found. Particularly cuticle-bearing compression floras are extremely rare in the Antarctic. The aims of this project are: (1) asystematic study of the newly discovered floras, based on cuticles and anatomically preserved material, (2) palaeoecological and -climatological interpretations of these floras,and (3) the establishment of a more detailed biostratigraphic framework for the Mesozoic sedimentary sequence in the Transantarctic Mountains. This study will thus contribute to abetter understanding of the palaeoenvironmental changes in East Antarctica during the earliest phase of the break-up of Pangaea.
