Abstract

A palynological analysis of the basinal volcaniclastic turbiditic Foura Sandstone Member within the Babulu Formation in Timor-Leste reveals rich assemblages including well-preserved material that correlates with the upper Ladinian–Carnian upper Staurosaccites quadrifidus–?lower Samaropollenites speciosus spore-pollen zones of Australia. The high diversity of conifer pollen in these assemblages indicates an association with microfloras from comparable latitudinal zones within Gondwana and an affiliation with the Onslow paleobiogeographic floral belt. The relationship between pollen and megafloral associations highlights the ecological flexibility of conifers, and their preeminent role in Triassic Gondwanan vegetation. The assemblages from the Foura Sandstone, including the new species Cadargasporites helbyi, Cadargasporites timorensis and Planctonites? comasii, point to the high diversity of vegetation in the area and the need for further studies.

期刊介绍： The Review of Palaeobotany and Palynology is an international journal for articles in all fields of palaeobotany and palynology dealing with all groups, ranging from marine palynomorphs to higher land plants. Original contributions and comprehensive review papers should appeal to an international audience. Typical topics include but are not restricted to systematics, evolution, palaeobiology, palaeoecology, biostratigraphy, biochronology, palaeoclimatology, paleogeography, taphonomy, palaeoenvironmental reconstructions, vegetation history, and practical applications of palaeobotany and palynology, e.g. in coal and petroleum geology and archaeology. The journal especially encourages the publication of articles in which palaeobotany and palynology are applied for solving fundamental geological and biological problems as well as innovative and interdisciplinary approaches.
