“…2). This horizon is located in the Huerva Member of the Fombuena Formation and is middle to early late Berounian (lower to middle Katian, Ka1-2 stage slices) in age (Villas, 1995). Locality 1 is located about 1 km west of the village of Fombuena (41º8'53''N,1º12'16''W) and corresponds to the F4 locality (Peña del Tormo section) of Villas collected from the Castillejo Formation (locality 3) is located about 1.5 km northeast of Fombuena village and corresponds to the F1 locality of Villas (1985).…”

“…Higher in the section, occurrence of Dalmanella unguis unguis Sowerby and Murchison, 1839 in the middle horizons of the member suggests correlation with the Marshbrookian (lower Katian, Ka1 stage slice). Finally, the uppermost levels of the Huerva Member have yielded a late Berounian (lower to middle Katian, Ka1-2 stage slices) fauna (Villas, 1995).…”

Abstract.-A diverse crinoid fauna is described from the Upper Ordovician (Katian) Fombuena Formation from the eastern Iberian Chains of Spain. New crinoids include the diplobathrid camerates Fombuenacrinus nodulus n. gen. n. sp., Goyacrinus gutierrezi n. gen. n. sp., Dalicrinus hammanni n. gen. n. sp., and Ambonacrinus decorus n. gen. n. sp.; the monobathrid camerate Eopatelliocrinus hispaniensis n. sp.; and the cladid Picassocrinus villasi n. gen. n. sp. A new occurrence of Heviacrinus melendezi Gil Cid, Domínguez Alonso, and Silván Pobes, 1996 is also documented from the Castillejo Formation (Darriwilian, Middle Ordovician) from the eastern Iberian Chains of Spain. The Fombuena Formation comprises a Gondwanan crinoid assemblage from a high paleolatitude and has the highest crinoid diversity of any currently known Katian Gondwanan fauna. This assemblage is compared to other Katian age faunas around the globe, and its paleobiogeographic implications are discussed.

“…20). Only one species of Iberomena has been described, I. sardoa (Vinassa de Regny, 1927), whereas four species have been ascribed to the Kjaerina (Villasina) subgenus: (1) Kjaerina (V.) pedronaensis Colmenar, 2016, the type species, from (Villas, 1995) known from the Central Iberian Zone (uppermost "Bancos Mixtos", Spain; lower part of the Porto de Santa Anna Formation, Portugal) and from the Armorican Massif (lower and middle parts of the Rosan Formation, assigned to the upper Berounian-lower Kralodvorian -see discussion in next chapter); and (4) Kjaerina (V.) meloui Colmenar, 2016 from the Kralodvorian of the Armorican Massif (limestones of the upper part of the Rosan Formation), present also in the association studied here. The last two species may be used as key elements for subdividing the Kralodvorian (see next chapter).…”

“…Among them, Kjaerina (V.) meloui (Colmenar, 2016), from the Rosan Formation of the Armorican Massif is exclusively Kralodvorian. On the other hand, Kjaerina (V.) almadenensis (Villas, 1995) from the Spanish Central Iberian Zone ranges from the uppermost Berounian to the Kralodvorian. In the Rosan Formation Kjaerina (V.) meloui has only been recorded from above the levels of occurrence of Kjaerina (V.) almadenensis within the Rosan Formation (Colmenar 2016).…”

The stratigraphy, brachiopod systematics and palaeoecology of the Upper Ordovician succession from the Cabrières Klippes, at the eastern ending of the southern slope of the Montagne Noire (southern France) are studied. Two new formations have been formally introduced: the Glauzy Formation (middle Katian, Ka2, in its uppermost fossiliferous strata) and the Gabian Formation (middle-upper Katian, Ka2-Ka4), to characterize, respectively, the thickly bedded quartzitic sandstones overlying volcaniclastic rocks, and the conformably overlying marls and limestones, rich in bryozoans, echinoderms and brachiopods. The systematic palaeontology of the brachiopods yielded in the uppermost beds of the Glauzy Formation has been studied, and five taxa are described, including a new platyorthid genus and species, Proclinorthis vailhanensis. The palaeoecological analysis of the Glauzy Fm., using both taphonomical and functional- morphological criteria, has allowed for the introduction of a new formal palaeoecological unit, the Svobodaina havliceki Community. It characterizes the recurrent low-diversity brachiopod association, usually dominated by S. havliceki, frequent in quartzitic sandstone lithofacies of the Upper Ordovician outcrops throughout southwestern Europe. It is interpreted as having developed in the shore face environments of the Benthic Assemblage 3 (BA-3), along the Gondwanan Mediterranean margin during the early- and mid-Katian. This new community is bounded coastward by an undescribed rhynchonellid community (BA-2) and seaward by the Nicolella Community (also BA-3), during its latest time span. This study allows a better understanding of when, why and how occurred the replacement of Gondwanan endemic associations, represented by the S. havliceki Community, by immigrant associations from low-latitude platforms, represented by the Nicolella Community, coinciding with the global warming Boda event
