“…The ecological void caused by the ETMEE in both European and Mediterranean areas was filled in by Soaresirhynchia bouchardi in the aftermath of the Extinction, a species with opportunist features (García Joral and Goy, 2000;Gahr, 2005, García Joral et al, 2011, and later on by other species, Homoeorhynchia and Telothyris being the more representative genera. S. bouchardi extends over a wide area of Western Tethys, as stated earlier, whereas the subsequent assemblage is more restricted to westernmost areas, including the Andean Region in South America (Manceñido, 2002). The development of the Spanish Province lasts only until the Aalenian, when the former European -Mediterranean paleobiogeographical pattern is re-established.…”

“…At the beginning of the Jurassic, this area was located near the southern margin of the AlKaPeCa Microplate From a paleobiogeographical point of view, this area was situated near the margins of Africa and Iberia (Martín-Algarra and Vera, 2004), close to the western boundary between the Mediterranean and the European Provinces (the latter also referred to as the Northwestern European) (cf. Ager, 1967Ager, , 1971Ager, , 1973Vörös, 1977Vörös, , 1984Vörös, , 2002Vörös, , 2005Manceñido, 2002).…”

ABSTRACT.A shallow marine invertebrate association is reported from a new Early Jurassic locality namely La Casilda, which is situated in the southwestern region of the Chubut Basin (Patagonia, Argentina). The marine deposits of La Casilda are located in the Río Genoa valley and bear a diverse invertebrate fauna including bivalves, gastropods, brachiopods, echinoderms and corals. A preliminary taxonomic analysis of the invertebrate fauna suggests that La Casilda deposits belong to the Mulanguiñeu Formation of late Pliensbachian-early Toarcian age, and may be coeval with those from the marine localities previously sampled in other regions of the Río Genoa valley. The preliminary results of a biodiversity analysis displayed that La Casilda is one of the most diverse localities at the Chubut Basin and could be assigned to the biofacies at the mixed siliciclastic-carbonate ramp proposed for the marine Early Jurassic at the Andean Basin of northern Chile. The evolution of the marine transgression during the early Pliensbachian-early Toarcian is also interpreted here in a time scale based on ammonite faunas, giving a preliminary temporal reconstruction of the entire Chubut Basin. Keywords: Invertebrates, La Casilda, Mulanguiñeu Formation, Chubut Basin, Argentina. RESUMEN. Una nueva localidad marina de edad jurásica temprana en la cuenca sudoccidental del Chubut, Argentina. Una asociación de invertebrados marinos de aguas someras se registró en una nueva localidad perteneciente al Jurásico temprano denominada La Casilda, la que se sitúa en la región suroeste de la cuenca del Chubut (Patagonia, Argentina). Los depósitos marinos correspondientes a La Casilda se encuentran en el valle del Río Genoa y comprenden una diversa fauna de invertebrados, incluyendo bivalvos, gastrópodos, braquiópodos, equinodermos y corales. Un análisis taxonómico preliminar de dicha fauna sugiere que los depósitos de La Casilda pertenecen a la Formación Mulanguiñeu, cuya edad es Pliensbachiano tardío-Toarciano temprano, y a su vez podrían ser coetáneos con los depósitos marinos de otras localidades muestreados previamente en el valle del Río Genoa. Resultados preliminares de un análisis de biodiversidad muestran que La Casilda es una de las localidades más diversas en la cuenca del Chubut y podría ajustarse a las biofacies correspondientes a la rampa mixta siliciclástica-carbonatada propuesta para la Cuenca Andina del Jurásico temprano marino del norte de Chile. La evolución de la transgresión marina que tuvo lugar durante el Pliensbachiano temprano-Toarciano temprano también se interpreta aquí en una escala de tiempo sobre la base de la fauna de ammonites, dando una reconstrucción temporal preliminar de toda la cuenca del Chubut.Palabras clave : Invertebrados, La Casilda, Formación Mulanguiñeu, Cuenca del Chubut, Argentina. 350 A new eArly JurAssic mArine locAlity from southwestern chubut bAsin, ArgentinA.

The Pliensbachian-Toarcian transition was a period of changes in long-term environmental conditions leading up to the Early Toarcian Mass Extinction Event (ETMEE), which resulted in a noticeable extinction and turnover in the marine biota. The westernmost Tethyan basins, especially the peri-Iberian platforms, provide an exceptional brachiopod record to better understand the adaptive strategies and the severe ecological effects of these faunas within the marine ecosystems. This event marks a critical interval in the evolutionary history of the Phylum Brachiopoda as two orders, the Athyridida and Spiriferinida, became extinct. Evolutionary patterns displayed by several taxa from these groups and some rhynchonellids typifying deep-water habitats are analyzed across this biotic crisis spanning several Mediterranean and NW-European basins. New work performed in La Cerradura section, a deep pelagic trough from the South-Iberian palaeomargin, reveals two new taxa (Koninckodonta sumuntanensis and Atychorhynchia falsiorigo) herein described. This newly documented fauna supports pre-extinction dwarfing and resilience in deep refugia linked to the ETMEE, and an episode of speciation which is interpreted in terms of a pre-extinction radiation. In the ETMEE repopulation phase an opportunistic strategy occurs typified by Soaresirhynchia bouchardi, and a case of homoplasy involving post-extinction pioneers (Elvis taxon) is detected. Similar adaptive strategies occurred associated with other mass extinctions such as the Permian/Triassic and the Cretaceous/Paleocene events, supporting a possible standard pattern in the response of the brachiopod fauna to such biotic crises and shedding light on the ecological effects of the mass extinction events. •
