“…This fauna is characterized by the presence of the obolids Glossella and Lingulasma , which are related to Laurentian and Baltic faunas, and the siphonotretid Chilcatreta , which was originally described as endemic to the Precordillera. Nevertheless, Lavié and Benedetto (2020) recently have described an older record of the genus Chilcatreta from the Famatina Range, Suri Formation (upper Floian), showing affinities with the West Gondwana region.…”

“…The upper Cambrian linguliform assemblage was described by Holmer et al (1999) from carbonate olistoliths of the Precordillera Basin, in the Province of Mendoza. Recent reports also come from nearby basins, such as the volcaniclastic Lower Ordovician units from the Famatina region (Lavié and Benedetto, 2020). Holmer et al (2016) reported a list of taxa from the Lower Ordovician of the San Rafael region in the southernmost extent of the Precordillera.…”

New linguliform microbrachiopods from the Middle Ordovician are described and illustrated. This fauna was recovered from the uppermost beds of the San Juan Formation in two sections of the Central Precordillera (Argentina), which are accurately dated to the Lenodus pseudoplanus Zone (middle Darriwilian). The fauna consists of the obolid Luthieria diminuta n. gen. n. sp., and the acrotretids Eoconulus tucunucoensis n. sp., Conotreta andina Lavié, Serra, and Feltes, Scaphelasma zharykensis Popov, and Numericoma rowelli Holmer et al. This low-diversity lingulate association displays close similarities with coeval faunas that inhabited the Laurentia, Baltica, and Kazakhstanian regions, in agreement with evidence from other linguliform and rhynchonelliform brachiopods.

“…The identification of the two specimens is based on the presence of the wide limbus, the shape of the pedicle groove and the faint visceral areas on both valves, features which, according to Mergl (2002) distinguish Lithobolus from Leptembolon Mickwitz, 1896. The latter genus is known from the Floian of the Famatina Basin in western Argentina (Lavié & Benedetto, 2020) and the Dapingian of Bohemia (Mergl, 1996(Mergl, , 2002. Although slightly deformed, the Belgian specimens (e.g.…”

Lower Ordovician linguliformean brachiopods from the Stavelot–Venn Massif (Belgium and Germany) are described systematically for the first time. The material comprises specimens from the Jalhay (Solwaster Member) and Ottré (Les Plattes Member) formations of Tremadocian and Floian ages, respectively. The Solwaster Member yielded a relatively diverse assemblage of nine species of lingulide (e.g. Lingulella lata, Lithobolus sp., Broeggeria sp.) and acrotretide (Acrotreta? sp.) whereas only one siphonotretide species (Celdobolus sp.) is recognised from the base of the Les Plattes Member where it is associated with conodonts of the Paroistodus proteus Zone. The assemblage from the Solwaster Member, although not abundant, is much more diverse than that of the contemporaneous Chevlipont Formation in the Brabant Massif (Thyle Valley, Belgium). Some of the taxa identified in the Stavelot–Venn Massif represent some of the youngest occurrences and first occurrences documented in Avalonia.

“…Paleozoic and modern Lingulida (Brachiopoda) occur in a wide variety of environments, ranging from nearshore to bathyal, although they are common in intertidal, shoreface, and offshore environments 1 – 13 . An endobenthic lifestyle in lingulides has been established since the Early Ordovician (Cambrian endobenthic evidence remains contested 14 – 17 ).…”

Deep-sea Ordovician lingulide brachiopods and their associated burrows suggest an early colonization of proximal turbidite systems

Trace fossils from Ordovician deep-marine environments are typically produced by a shallow endobenthos adapted to live under conditions of food scarcity by means of specialized grazing, farming, and trapping strategies, preserved in low-energy intermediate to distal zones of turbidite systems. High-energy proximal zones have been considered essentially barren in the early Paleozoic. We report here the first trace and body fossils of lingulide brachiopods in deep-marine environments from an Upper Ordovician turbidite channel-overbank complex in Asturias, Spain. Body and trace fossils are directly associated, supporting the interpretation of a lingulide tracemaker. Ellipsoidal cross-section, cone-in-cone spreite, and spade morphologies suggest the specimens belong to Lingulichnus verticalis. The oblique orientation in both trace and body fossils is the result of tectonic deformation. The organisms were suspension feeders showing escape, dwelling, and equilibrium behaviours controlled by sedimentation rates associated with turbidite deposition. These trace fossils and their in situ producers represent the oldest evidence of widespread endobenthos colonization in high-energy, proximal areas of turbidite systems, expanding the bathymetric range of Lingulichnus and the variety of behaviours and feeding styles in early Paleozoic deep-marine environments.
