BRYOZOAN FAUNA FROM THE OOLITIC LIMESTONE FROM PAJAREJOS, SW SPAIN

Abstract

Outcrops of Devonian rocks at the hill of Pajarejos near Campillo de Llerena, south-western Spain, expose oolitic limestone which contains abundant fragments of bryozoans, whereas other macrofauna is scarce. Eight bryozoan species were identified, which date the outcrop as Middle Devonian. The assemblage shows close affinities with that described from Sabkhat Lafayrina reef complex in Western Sahara, which is situated more than 1,000 km further south today. The studied association supports the previously proposed hypothesis that South-western Spain belonged to the northern margin of Gondwana during the Middle Devonian.
