ABSTRACT
The Jurassic floras of Europe show considerable diversity. To examine the extent of this diversity
and its possible causes we used multivariate statistical methods (cluster analysis, PCA, NMDS) to compare
all significant Jurassic floras in Europe. Data were based on 770 taxa from 46 fossiliferous occurrences
(25 units) from France, Germany, Greenland, Hungary, Italy, Norway, Poland, Romania, Scotland, Serbia,
Sweden, Switzerland, and the United Kingdom. Statistical analyses were applied at species level and genus
level, and also performed for the major plant groups. The genus cladograms show affinities between different
localities based on environmental factors, while the cladograms based on species affinities indicate only
taxonomical correlations. The study shows that locality age does not seem to be of paramount importance for
floral composition.
