The genus Parabailiella Thoral, 1946 (Trilobita) from the middle Cambrian of the Cadenas Ibéricas (NE Spain).

Abstract

We analysed the record of the genus Parabailiella Thoral, 1946 in the middle Cambrian of the Cadenas Ibéricas. The four species assigned to the genus have been identified and described in this region for the first time. All the four species are recorded in Jarque 1 section while only some of them are recorded in the rest of the studied sections. The biostratigraphic distribution of the Parabailiella is middle Leonian to basal upper Caesaraugustan, which is equivalent in the International Subcommission on Cambrian Stratigraphy (ISCS) scale to the most part of the Cambrian Stage 5 and to the lower part of the Drumian Stage. The palaeogeographic distribution of the genus is restricted to the Mediterranean region, particularly the European Platform of the Perigondwana region.
