“…This scenario connects with the evolutionary factories model proposed by Andrade et al (2016) as supplier for the late Toarcian-early Aalenian peri-Iberian brachiopod biochoremas. This evolutionary model can predispose the biogeographical distribution of Recent brachiopods already established for the Early Jurassic faunas (Vörös 2005, Zezina 2008, Thuy et al 2014, Andrade et al 2016.…”

“…S. bouchardi likely originated in another similar resilient deep-water environment and, in favourable environmental conditions, colonised peri-Iberian basins (Andrade et al 2016). Furthermore, the development of very simple and conservative morphotypes in these resilient habitats allows reaching a high diversification and provides them the potential to export taxonomic diversity, once again confirming the great dispersal potential of the deep-sea benthic biota (Vörös 2005, Thuy et al 2014.…”

“…Thuy et al 2014, Andrade et al 2016 suggested that the deep-sea fauna is not only more resilient to an extinction event than those inhabiting shallow-water, but that in situ diversification in these deeper-water habitats was probably higher than generally supposed. Hence, these areas should not be considered only refugia but as resilient environments that can produce and export high taxonomic diversity (Vörös 2005, Lindner et al 2008, Thuy et al 2014.…”

“…Nevertheless, the remaining fauna and geochemical proxies (Reolid et al 2014a) suggest a younger date for this assemblage within the elegantulum Subzone and the NJT6 Zone (CNZ), but without reaching the upper part of this subchronozone, as indicated by the FOD of Soaresirhynchia bouchardi, regarded as an initial coloniser in the extinction aftermath in most of the Western Tethyan basins (e.g. García Joral & Goy 2000, García Joral et al 2011, Baeza Carratalá et al 2011, Andrade et al 2016. This is consistent with the record of an early T-OAE pulse in the CE section plausibly in the basal layers of the serpentinum Zone (Reolid et al 2014a), bearing in mind that the expanded section in the CE area supports a significant thickness for the basal serpentinum Zone deposits.…”

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. •

The record of brachiopods in the Lower Toarcian of the Balearic Islands is described after a reassessment of previous works and new samplings in the Tramuntana Range of Mallorca. The recognized species have been assimilated to the assemblages described in the Iberian Range in the Tenuicostatum and Serpentinum biozones. Moreover, a detailed comparison with other Western Tethys basins and the study of the dispersion of the brachiopod faunas in relation with the Early Toarcian Oceanic Anoxic Event, allow to refine the paleobiogeographic relationship of the Balearic brachiopods. They belong to the Euro-Boreal Province of brachiopods in the Tenuicostatum Biochron and correspond to the”Spanish Fauna” that emerged after the deep paleobiogeographic disruption that took place at the base of Serpentinum Biochron. The occurrence of Prionorhynchia msougari Rousselle in the Serpentinum Zone of Mallorca indicates that, within this last assemblage, there would be a closer connection between the Balearic region and the southern margin of the Tethys (Betic and North African basins) than with the northern margin (Eastern Iberian Platform System and Eastern Pyrenees). This paleobiogeographic conclusion is consistent with the supposed position of the Balearic area in the Early Toarcian, on the southeastern margin of Iberia and near the Alboran and Kabylian margins.
