Intraspecific variation in Wenlock tabulate corals from Saaremaa (Estonia) and its taxonomic implications

Abstract

Different aspects of intraspecific variation in Wenlock tabulate corals are discussed. Intracorallum and intraspecific variation is demonstrated in specimens within the collection from one locality. The diagnostic characters of Halysites senior Klaamann and Catenipora oriens Klaamann and those of Paleofavosites secundus (Klaamann) and Favosites jaaniensis Sokolov overlap and therefore these species are regarded as synonyms. Propora raricellata Sokolov is a possible synonym of P. tubulata (Lonsdale), because the character differentiating these species is variable.
