CORNUTE SOLITARY CORALS OF THE TYPE CYATH AXONIA-FAUNA FROM THE LOWEREMSIAN OF THE EASTERN CANTABRIAN MOUNTAINS, NORTHWEST SPAIN

Fifteen species of undissepimented solitary horn corals (Coelenterata, Rugosa) from the Lower Devonian Abadia Formation of the Cantabrian Mo untains in Northern Spain are described belonging to the genera Entero lasma, Schindewolfia, Boolelasma, Syringaxon, Nicholsoniella, Adradosi a, Ufimia, Oligophyllum (Pentelasma) and Pentaphyllum. Three species a re new: Syringaxon smithioides nov, sp., Ufimia tabulata nov, sp., and another unnamed new species of Ufimia;Adradosia barroisi simplex PLUS QUELLEC, 1981 has been renamed as A. b. plusquelleci nov. nom. because of homonymy. The new Cantabrian coral fauna represents the most diver se Cyathaxonia fauna sensu Hill of Lower Devonian age; dissepimented c orals are almost completely missing. Several elements are related to s pecies in Germany (Hart Mts. and Thuringia), Bohemia, Turkey and the U rals. Some coral-bearing horizons contain ammonoids, mostly Erbenocera s filalense and several species of Mimagoniatites indicating a late Lo wer Emsian age.
