Upper Triassic–lowermost Jurassic palynology and palynostratigraphy: a review

Geological Society, London, Special Publications, 2010
Abstract This review advances understanding of the palynostratigraphy of the Late Triassic–Early Jurassic by correlating the established palynozonations for the northern and southern hemispheres. Previous palynological studies have contributed greatly to our understanding of the biostratigraphy, paleoclimatology and paleogeography of the ...
