The last laveineopterid – The systematic and floristic relationships of Laveineopteris nervosa (Medullosales) from the Stephanian of the Czech Republic

Abstract

Stephanian fronds from intra-montane basins of the Bohemian Massif in central Europe, previously named Neuropteris nervosa Šetlík, have been transferred to the fossil-genus Laveineopteris. This makes it the youngest known species of that genus. Current evidence suggests that they were more closely related to the Laveineopteris rarinervis fronds from the late Westphalian / earliest Stephanian lowland floras, rather than to Laveineopteris bohemica from the middle Westphalian intra-montane basin floras.
