Frond architecture of the seed-fern Macroneuropteris scheuchzeri, based on Pennsylvanian specimens from the Northern France coal field

An exceptional collection of remarkably informative specimens of Macroneuropteris scheuchzeri from the Bolsovian (ex Westphalian C) of the Northern France coal field shows a bifurcate semi-pinnate type of frond architecture. This collection allows the circumscription of the variability of the main characters of the frond. Reconstructions of the frond and of the whole plant are proposed. Morphological, taxonomical, and palaeogeographical implications are analyzed.

期刊介绍： Section B of Palaeontographica publishes contributions to palaeobotany, i.e. papers on morphological traits, systematics and phylogenetic features of plants as well as papers on palaeoclimatology and palynogeography. Especially worth mentioning are the comprehensive monographs published in Palaeontographica B on specific floras or plant groups. Often palaeoclimatic or stratigraphic problems are clarified by resorting to palaeobotanical data published in Section B of Palaeontographica. Throughout the last decades, numerous objects important to palaeophytology have been found in many places all over the world. As Palaeontographica publishes papers on floras on any parts of the world to report world-wide research, contributions in German, English and French have been published since the beginning of the journal, today English language publications are preferred. Palaeontographica B is of interest to palaeobotanists, palynologists, palaeoclimatologists, stratigraphers and the libraries of all institutions engaging in such research.
