RT Journal Article T1 Descubrimiento de Arístocystites metroi Parsley y Prokop, 1990 (Echinodermata, Diploporita) en el Ordovícico medio centroibérico (España) T1 First Middle Ordovician record of Arístocystites metroi Parsley and Prokop, 1990 (,Echinodermata, Diploporita) in the Central Iberian Zone (Spain) A1 Gutiérrez Marco, Juan Carlos A1 Baeza, E. AB The first record outside Bohemia of the recumbent diploporid Aristocystites metroi is presented. It consists of a remarkable specimen from the Dobrotivian shales of CaIzada c/e Calatrava (Central Iberian Zone). The Spanish occurrence of the species is markedly older (Dobrotivian: Middle Ordovician) than in Bohemia (Zahoranlan and Kosovian; Upper Ordovician). Our specimen derives also from much shallower environments with respect to the type material PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/11378 UL http://hdl.handle.net/10272/11378 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 1 jun 2026
