Previous multivariate statistical analyses identified at least seven associations of sporomorphs within a major vegetational group of late Triassic-earliest Jurassic times identified as corresponding to arctic or cool-temperate climatic conditions. Detailed examination of how these associations responded to the climatic changes near the Triassic-Jurassic boundary allows them to be classified in terms of their thermophily and drought tolerance. These deductions also give rise to a fairly detailed reconstruction of climatic changes at the time. Consideration of the presumed family affinities of the various sporomorphs gives some support to the climatic interpretations; and allows tentative reconstructions of some of the vegetation.
