Where: Spain (43.6° N, 6.0° W: paleocoordinates 40.8° S, 31.2° E)
• coordinate estimated from map
When: Aguión Formation (Rañeces Group), Late/Upper Emsian (402.5 - 391.9 Ma)
• Aguión Fm. hosts one of the seven reefal episodes described in the Devonian of the Cantabrian zone
• formation-level stratigraphic resolution
Environment/lithology: perireef or subreef; green marl and red marl
•and Arbizu (1986) into three informal lithostratigraphic units with different lithological and
•faunal characteristics: a lower calcareous unit, a middle marly-shaly unit and an upper unit of green and red marls. It is the last unit where these bryozoan-coral associations have been seen. The unit is 24 m thick and contains not only numerous bryozoans and corals, but also abundant crinoids and brachiopods
Size class: macrofossils
• upper Emsian crops out showing a rich benthic fauna including mainly bryozoans, crinoids, corals and brachiopods
Preservation: recrystallized, replaced with dolomite
Collected by JLSA in 2017
• 12 samples, three of them belong to the collections of the Museum of Geology, University of Oviedo, rest was collected by JLSA in 2017 in the field (housed in the paleontological collections of the Museo de la Mina de Arnao
