Article: Architecture of the Upper Carboniferous pteridosperm frond Macroneuropteris macrophylla

This paper presents the first full morphological description of Macroneuropteris macrophylla, the type species of its genus. The fronds are very similar in size to the more widely distributed Neuropteris, but are significantly less divided; the M. macrophylla pinnules are homologous to segmented, tertiary pinnae in Neuropteris. M. macrophylla is known only from westernmost Europe and easternmost North America.
