Leaf impressions

Leaf impressions

A recent paleobotanical study identified 64 taxa among the large collection of macrofloral remains, based on a sample of nearly 15 thousand leaves (Hably, 1985, 2016). The assemblage is dominated by laurophyllous plants, indicative of a vegetation in a warm and humid, subtropical climate. Most of the abundant plant remains are in the basal part of the rhyolite tuff, but 27 plant species have been identified from leaf imprints on the palaeosurface (footprint sandstone), too.

The flora was dominated by laurophyllous taxa, like numerous species of magnolias, laurels, ancient avocados and later extinct walnuts. In the palaeobotanical special literature this extremely laurophyllous flora is classified as a separate group and mentioned as „Florenkomplex Ipolytarnóc” (Mai, D. 1995).

Quite exotic plants, like ancient tropical ivies, sabal and rattan palms with different lianas were also present in the flora. The vegetation was quite luxuriant and diverse and almost exclusively ancient palaeotropical elements appeared in it.
