New callistophytalean species from the Duckmantian of the Kladno-Rakovník Basin, Czech Republic

Popis výsledku v původním jazyce

Small-pinnuled last order pinnae of a newly described taxon have previously been found relatively commonly at the Pchery locality, Theodor Coal Mine, in the Kladno-Rakovn &amp; iacute;k Basin. Although foliar fragments of this plant have been known for over a century, the remains have yet to be formally identified because they share features characteristic of the neuropteroids (venation and cordate base of pinnules) and sphenopteroids (small pinnules). This taxon shows some resemblance to the species Pseudomariopteris cordato-ovata and Mariopteris occidentalis, both belonging to Order Callistophytales. However, the remains from the Theodor Mine do not have the lobed pinnules known for Mariopteris occidentalis, nor the prominent basal lobe typical of mature Pseudomariopteris cordato-ovata. Nonetheless, cuticles of all three of these species demonstrate some similarities, including adaxial cuticles showing elongated cells with very small trichome bases, and stomata with polar prolongation. However, differences also exist. The species from the Theodor Mine has small trichomes formed by barrel-shaped cells, whereas Mariopteris occidentalis has multicellular trichomes up to 0.5 mm long, and Pseudomariopteris cordatoovata has resin bodies rather than trichomes. The overall similarity of cuticular structures and differences in pinnule morphology support erection of a new genus and species within Order Callistophytales. The name Neuromariopteris scandens gen. et sp. nov. alludes to the similarity to neuropteroids. The taxon probably was a creeping plant, as is known for all callistophytaleans. This species was probably an element of vegetation growing on the Proterozoic ridge slopes surrounding the coal basin. The exotic character of this flora is caused probably by edaphic factors.
