Triassic paleoecology in south Victoria Land: A vegetation model (plant fossils and palaeosols) in Triassic alluvial plains

Triassic plant fossils and palaeosols were sampled from four mountains (Mt Bastion, Portal Mountain, Shapeless Mountain and Allan Hills) with the aim of establishing a model of vegetation on the Triassic alluvial plain. The Triassic vegetation was described in terms of communities, soil/plant relationships, climate and palaeohydrology. Palaeosols with associated vegetation were recorded at Portal Mountain and Allan Hills and undeveloped paleosols with root traces at Mt Bastion. Fossil types recorded were: Dicroidium, Xyopteris, Johnstonia, Sphenobaiera, Phoenicopsis, Neocalamites, Lepidopteris, microsphorophylls, roots, infilled root traces, peat, horizontal and vertical burrows.
