Neuropteris is an extinct seed fern that existed in the Carboniferous period, known only from fossils. Major species include Neuropteris loschi.
‘Neuropterids’ are one of the dominant groups of Carboniferous fossil-plant adpressions. The original definition of Nevropteris, initially given as a section of the genus Filicites, was based only on the shape, the mode of attachment to the rachis, and the venation of the pinnules. Subsequently discovered information has shown that the originally defined taxon in fact comprises many genera belonging to several distinct families of Pteridosperms, which are distinguished on various features of frond architecture, male and female reproductive organs and apparatuses, anatomy, and morphology and venation of the pinnules. Unfortunately, these characteristics are not equally known within each group, even at a general level, and are not always available through usual palaeobotanical collecting. However, it is essential to reach the most precise, ‘natural’ level of taxonomy for the decipherment of the many interrelated problems raised by palaeobotanical studies, i.e. evolution, biostratigraphy, palaeobiogeography, palaeoecology and, as a feedback consequence, systematics. Despite restricting the analysis mainly to the external morphological characters, the ‘Neuropterids’ provide a fine example of such interrelated fundamental questions.
