Abstract
Paralogania species in the Rootsiküla (Wenlock) and Paadla (Ludlow) stages from Saaremaa Island, Estonia, were re-studied. Extremely well preserved scales of P. martinssoni (Gross) were described from Silma Cliff (Himmiste Beds of the Paadla Stage) and compared with the scales from Vesiku Brook (Vesiku Beds of the Rootsiküla Stage), the type locality of the species. Paralogania kaarmisensis sp. nov. was established on the basis of relatively large, strongly elongate scales carrying a row of very fine spines laterally of the crown; the scales have one to two fine oblique ridges above the row of spines. The new species has a short range in the Phlebolepis elegans Biozone (Ludlow, Upper Silurian).
