Early Late

The first plants related to the ferns are represented by several extinct groups that emerged during the Devonian. Among them, the iridopterids are closely allied to the sphenopsids, a group represented today by the genus Equisetum. They have been documented in Middle to early Late Devonian deposits of Laurussia and the Kazakhstan plate. Their Gondwanan record is poor, with occurrences limited to Venezuela and Morocco. Here we describe a new genus from a late Late Devonian locality of New South Wales. It is represented by a single anatomically preserved large stem characterized by a star-shaped vascular system with protoxylem strands located at rib tips, and by a lack of secondary tissues. Within the first fern-like plants, this stem shares the largest number of characters with iridopterid axes but differs by the pattern of its vascular system. Keraphyton mawsoniae gen. et sp. nov. adds a new record of early fern-like plants in eastern Gondwana. It provides new insights into the anatomical diversity within this key group of plants and supports the distinctiveness of the Australian flora in the latest Devonian.

Remigolepis walkeri sp. nov. from the Mandagery Sandstone (late Devonian) near Canowindra, New South Wales (NSW), is the second species of Remigolepis to be described from Australia, the first being from near Grenfell, NSW. Remigolepis walkeri possesses unusual paired suborbital plates with a large oval structure at the anteromesial edge of the plate, representing an attachment for the autopalatine portion of the palatoquadrate. Among asterolepidoids, this morphology is most similar to Pterichthyodes. Suborbitals of Remigolepis from East Greenland are said to possess a transverse ridge on the internal surface, similar to the bothriolepids Bothriolepis and Nawagiaspis. However, some specimens from East Greenland may show a morphology more similar to Remigolepis walkeri. The internal morphology of the suborbital plates is constant in the population of Remigolepis from the Canowindra locality, suggesting the presence of a single species despite the presence of more than 1000 individuals in this fauna. The morphology of the caudal fin of Remigolepis walkeri is similar to Remigolepis sp. from near Eden, NSW, and Asterolepis ornata, but differs from Remigolepis sp. from China. The morphology of the pectoral and caudal fins of R. walkeri indicate a bottom-dwelling lifestyle, whereas Bothriolepis from the same fauna may have been able to generate sufficient lift from the pectoral fins to enter the water column on a regular basis.
