- Abstract
The locality Züjar at the boundary between the Badajoz and Córdoba provinces belongs to the Obejo-Valsequillo-Puebla de la Reina Domain. Within the fossiliferous reefal carbonates of Pragian age cropping out in Züjar, 10 stromatoporoid species and 7 rugose coral species are identified. The new rugose coral species Martinophyllum miriamae n. sp. is described. Hexagonaria soraufi Rodriguez Garcia, 1978 is a subspecies ofMartinophyllum ornatum Jell & Pedder, 1969. The Pragian fauna of Züjar is a typical fauna of the Old World Realm with remarkably close relationships to Arctic Canada and Australia. Most species have been recorded for the first time from Spain. No significant relationships to the Eastern Americas Realm are visible. Remarkable is, that none of the stromatoporoid species of Züjar is known from the famous Pragian reef complex of Konĕprusy in Bohemia, meanwhile the rugose coral fauna (e. g. Joachimastraea barrandei Galle, Hladil & May, 1999) shows some relations. Some of the species found are ancestors of important constructors of the Middle Devonian reef complexes, demonstrating that the roots of the Givetian-Frasnian reef complexes reach down to the Pragian.
