A new species of Praemichelinia (Tabulata) from the Emsian (Lower Devonian) of Colle (Cantabrian MountainS, NW Spain) and the occurrence of solenia-like pores in the genus

Abstract

This paper comprises a detailed systematic study of material corresponding to Tabulate corals found in the Upper Emsian (Lower Devonian) strata of the locality of Colle, on the southern slope of the Cantabrian Mountains (NW Spain) which is assigned to a new species of the genus Praemichelinia. This species is characterized by the large size attained by its main corallites and by the occasional development of complete concave tabulae, disposed in series coexisting with incomplete tabulae and tabellae. In addition, solenia-like corner pores are reported in the genus for the first time. The description of this new species allows to reaffirm the validity of the genus Praemichelinia, as also its peri-Gondwanic distribution during the Lower Devonian.
