New atopid trilobites from the early Cambrian Cumbres beds and Herrerias shale in northern Huelva Province, Andalusia, Spain are described and dated as middle-late Marianian (Cambrian Series 2, Stage 4). The study also recognizes the Laurentian species Pseudatops reticulatus for the first time in the Mediterranean subprovince. The associated trilobite assemblage in this study suggests an age close to the base of Cambrian Stage 4.
New atopid trilobites are described from the early Cambrian Cumbres beds and Herrerias shale of northern Huelva Province (Andalusia, Spain) and are dated as middle-late Marianian (Cambrian Series 2, Stage 4). New specimens of Atops calanus Richter and Richter, 1941 are described and the Laurentian species Pseudatops 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.
