Atopidae (Trilobita) in the upper Marianian (Cambrian Series 2, Stage 4) of Iberia

2020

AbstractNew atopid trilobites are described from the early Cambrian Cumbres beds and Herrerías shale of northern Huelva Province (Andalusia, Spain) and are dated as middle–late Marianian (Cambrian Series 2, Stage 4). New specimens ofAtops calanusRichter and Richter, 1941 are described and the Laurentian speciesPseudatops reticulatus(Walcott, 1890b) is recognized for the first time in the Mediterranean subprovince. The associated trilobite assemblage studied herein suggests an age close to the base of Cambrian Stage 4.
