Updated stratigraphic framework and biota of the Ediacaran and Terreneuvian in the Alcudia-Toledo Mountains of the Central Iberian Zone, Spain

Abstract: Se presenta en este trabajo una revisión actualizada de la estratigrafía del Ediacárico-Terranóvico del valle de Alcudia y los montes de Toledo, Zona Centroibérica. Se subdivide el Supergrupo infrayacente ediacárico del Alcudiense Inferior-Domo Extremeño en los Grupos del Guadiana (Formaciones de La Coronada y Sta. Ma de Zújar) y de Campanario (Formaciones de Botija, Monroy y Orellana). El supergrupo contiene varios acritarcos sin utilidad bioestratigráfica, así como dubiofósiles, pero su edad se ha establecid… Show more

“…The Fontanarejo Lagerstätte is of similar age toor perhaps slightly older thanthe Niutitang phosphorites as indicated by recent discoveries of Anabarella and an improved sedimentological correlation (Álvaro et al 2019;Álvaro & Lorenzo, 2021;this study). It therefore provides unique and valuable insights into early metazoan diversity, particularly allowing for the reconstruction of the major sponge branches.…”

“…plana in stratigraphically equivalent sedimentary rocks from the Alcudia anticline close to Ciudad Real in central Spain (i.e. 'Conglomerados de San Lorenzo', Pusa or Fuentepizarra formations: Pieren & García-Hidalgo, 1999;Vidal et al 1999;Pieren Pidal, 2000;Álvaro et al 2019;Álvaro & Lorenzo, 2021). Given this stratigraphic framework, the phosphorite deposits of Fontanarejo we studied are likely late Fortunianearliest Age 2 in age.…”

“…The boundary interval is particularly well studied in the type area of the group, the Ibor and Navalpino anticlines. Here, Cloudina-bearing limestones of the heterolithic Villarta Formation indicate a late Ediacaran age (Cortijo et al 2015;Álvaro et al 2019) whereas the overlying siliciclastic Arrocampo Formation includes in its basal part Central Iberia's earliest record of Treptichnus pedum as well as specimens of Sabellidites in levels above, indicating a basal Cambrian age (Álvaro et al 2019). Simón (2018) studied a succession of the Ibor Group including the Ediacaran-Cambrian transition in the Abenójar dome.…”

“…In contrast to the helcionellid specimens, the alleged anabaritids from the transitional beds were never described in detail or illustrated. Also, the exact stratigraphic levels and details of the lithology of the fossiliferous beds were not mentioned, aggravating a correlation with the subsequently revised stratigraphy of the Alcudia anticline (Pieren & García-Hidalgo, 1999;Álvaro et al 2019). In contrast to Vidal et al (1999) who regarded the Alcudia succession as entirely conformable, Álvaro et al (2019) describe it as noncontinuous, characterized by two major stratigraphic gaps.…”

“…Localized in the central part of the Iberian Massif, the CIZ is limited to the north by the Ollo de Sapo Anticline and to the south by the TPBCSZ (Álvaro et al, 2019). The CIZ is characterized by a large volume of Variscan granitoids (Roda‐Robles et al, 2018) and is dominated by metasedimentary rocks—thick Neoproterozoic–Lowermost Cambrian siliciclastic metasedimentary successions (Schist‐Greywacke Complex) generally unconformably overlaid by Ordovician sediments and volcanic–volcaniclastic series (M. F. Pereira et al, 2018; Rodríguez‐Alonso et al, 2004) and, in Portugal, subsequently overlain by the Armorican Quartzite Formation (M. F. Pereira et al, 2018).…”
