International audienceThe Lower Cambrian Pardailhan Formation of the Montagne Noire (Southern France) has yielded a diverse fossil assemblage including bivalved arthropods (the bradoriids Monceretia erisylvia gen. et sp. nov., Cambria danvizcainia sp. nov. and Matthoria? sp., together with Isoxys sp.) associated with trilobites, hyolithids, inarticulate brachiopods, sponge spicules, ichnofossils and chancelloriid sclerites. This assemblage provides new evidence about the biodiversity of Early Cambrian marine communities in palaeocontinentalGondwana. The bradoriids are Cambriidae, a familywith widespread distribution in offshore shelf marine environments during Early Cambrian times. The present study confirms the presence of cambriids within a subtropical latitudinal belt that encompasses Laurentia, Siberia and the Gondwanan margins from Southern France to South China. Although knowledge of the distribution of fossil cambriids is patchy, at the generic level they appear to be provincial, with Petrianna from Laurentia, Shangsiella and Auriculatella from South China, Cambria from Siberia and Gondwana (Armorica), and Monceretia gen nov. from Gondwana (Armorica). The presence of Isoxys in the Montagne-Noire confirms the cosmopolitan distribution of this genus in the Early and Middle Cambrian tropics. Cambriid bradoriids occupy a biostratigraphically narrow time interval, probably equating to part of the Atdabanian and Botomian stages of Russian terminology. Their presence in the Pardailhan Formation supports the notion of a Botomian age, determined from archaeocyathan evidence. The North American bradoriid genus Matthoria, also possibly present in the Pardailhan Formation, is reassigned to the Cambriidae

“…Bradoriid taxa from the Iberian Peninsula include one of the oldest forms known from West Gondwana, i.e., the cambriid Cordubiella pedrochensis Hinz-Schalreuter, Gozalo and Liñan, 2008 from the "Ovetian" (Lemdadella Biozone, late Issendalenian) of southern Spain. Younger Iberian taxa are represented by three hipponicharionids, i.e., Hipponicharion hispanicum Gozalo and Hinz-Schallreuter, 2002 from the lower Cambrian ("Marianian" = Banian) Alconera Formation of the Sierra Nevada, southern Spain, and two taxa described by Gozalo et al (2004) from the western Iberian Chains of northern Spain as Hipponicharion aff. hispanicum from the Daroca Formation (Hupeolenus Biozone) and Wimanicharion aff.…”

Bradoriid arthropods (class Bradoriida) are described for the first time from the lower-middle Cambrian boundary interval (regional Agdzian Stage) of the Franconian Forest in eastern Bavaria, Germany. The specimens originate from the Tannenknock and Triebenreuth formations, which are part of a shallow marine succession deposited at the margin of West Gondwana. Five different forms have been distinguished, Indiana aff. dermatoides (Walcott), Indiana sp., Indota? sp., Pseudobeyrichona monile sp. nov., and an undetermined svealutid, all of which belong to families that have previously been reported from and are typical of West Gondwana. However, at the generic level, all taxa are new for the region. Indiana is typical of shallow marine environments. So far it has been reported from Laurentia, Avalonia, and Baltica, and is considered to characterize the paleogeographic vicinity of Cambrian continents. Pseudobeyrichona has previously only been recorded from South China, and its new occurrence corroborates previous documentation of taxa from South China in northern West Gondwana. The presence of Indiana as a typical "western" taxon and Pseudobeyrichona among other typical "eastern taxa" confirms the unique biogeographical position of West Gondwana. The poorly known Indiana anderssoni (Wiman) and Indiana minima Wiman from the late early Cambrian of Scandinavia have been restudied in order to re-evaluate the two species and to refine the definition of Indiana. Indiana anderssoni represents a distinct species of Indiana, whereas I. minima is a pseudo-fossil.

“…It comprises bluish-grey and yellowish-grey shales, marly shales and scarce, very fine-grained sandstones, abundant carbonate nodules and some yellowish-grey dolostone, which, in places, show microbial lamination. Palaeoecological conditions changed up the section from restricted to more open sublittoral (Gámez et al, 1991;Liñán et al, 1992Liñán et al, , 1993bLiñán et al, , 2002Liñán et al, , 2008Gozalo et al, 1993aGozalo et al, , 2004Álvaro et al, 1993;Gámez Vintaned and Mayoral, 1995). In the RV2 section, the upper part of the Valdemiedes Formation is a 75 m-thick, monofacies succession of fossiliferous shales with some carbonate nodules and minor marly shales, white claystone and discontinuous greenish-grey very fine-grained sandstone interbeds ( Figure 5).…”

The classical lower-middle Cambrian boundary is approximately equivalent with the boundary of the Cambrian Series 2 and 3, which is now in the process of definition by the International Subcommission on Cambrian Stratigraphy. Currently, there are two oryctocephalid trilobite species first appearance data (FAD) that are suggested as possible markers of this level: Ovatoryctocara granulata Tchernysheva, 1962 and Oryctocephalus indicus (Reed, 1910), respectively. Until now neither of these two species has been recorded in the Mediterranean subprovince or Baltica. As a result, in these regions a level potentially correlating with either the FAD of Ovatoryctocara granulata or Oryctocephalus indicus has to be located using the available bio-, isotope-, and event-stratigraphy data.Carbon isotope signatures reveal global oceanic perturbations adjacent to the Cambrian Series 2 and Series 3 (former lower-middle Cambrian) boundary. This event, first called the Valdemiedes Event (it was defined in Murero, NE Spain; Liñán et al., 1993a), caused a noticeable extinction of trilobites, mostly olenellids and protolenids (which were replaced in some regions by paradoxidids), as well as an almost complete extermination of some other early Cambrian marine animals. Both isotope and palaeontological evidence show that the disappearance of olenellids in Laurentia, protolenids in Siberia and the appearance of the first Acadoparadoxides in Western Gondwana, Baltica, Avalonia, and Siberia, which was formerly thought to be a series of diachronous regional perturbations, were nearly contemporaneous events. Features of a global ecological crisis and faunal replacement being taken together with a pronounced global d 13 C org negative excursion would serve as the best indicator of the lower boundary of the Cambrian Series 3 and Stage 5 in the Mediterranean subprovince and is correlatable with the Ovatoryctocara granulata FAD. Another d 13 C org negative excursion followed by a positive shift occurs at a slightly younger level, which coincides with a transgression maximum and roughly is coeval with the Oryctocephalus indicus FAD, also proposed as a possible base of the Cambrian Series 3.
