The Mesophytikum ( ancient Greek μέσος mésos , German 'middle' and φυτικός phytikós , German 'vegetable' ) is a geological period in which the naked-seed plants (gymnosperms) formed the predominant plants . The term was formed in 1941 by the geologist Kurd von Bülow in analogy to the Mesozoic .
The beginning of the mesophytic at the border between the lower and upper perms was originally associated with an extinction event, but according to more recent findings no sharp boundary can be defined, as the transition from the fern-like plants (Pteridophyta) to the gymnosperms took place gradually and only in the triad was over. The end of the Mesophytic coincides with the lower / upper Cretaceous border , when the flowering plants (Magnoliopsida, formerly angiosperms) became the dominant class of seed plants.
