Correction to: Swiss J Geosci (2021) 114:18 https:// doi. org/ 10. 1186/ s0001502100395-5 Following publication of the original article (Pictet 2021), Dr. Pierre-Olivier Mojon protested officially about his past collaboration being ignored according to him and about the inappropriate use of his ostracod data. The publication of this erratum is thus necessary in order to clarify these points, correct inaccuracies and indicate clearly the sources of ostracod data lacking in the caption of figure 2, as the used references are only mentioned in a dispersed way within the main text. Despite a long lasting and fruitful collaboration between Dr. A. Pictet and Dr. P.-O. Mojon, major disagreements on the interpretation of the stratigraphic succession of the “Urgonian” deposits of the Swiss and French Jura hindered the collaborative redaction of a common, broad synthetic publication encompassing both the lithostratigraphic framework and new age constraints based—among other proxies—on ostracods and charophytes, two fossil groups for which Dr. P.-O. Mojon was originally involved. Since the publication of a revised lithostratigraphic scheme for the Cretaceous deposits of the Swiss and French Jura at the formation level (Strasser et al., 2016), it became clear to Dr. A. Pictet that further investigations and refinements were needed as concerns the Gorges de l’Orbe and Vallorbe formations, as defined at that time. Based on extensive personal field and laboratory work the author already outlined a new scheme in 2017, which was progressively consolidated as new data kept on accumulating and through consultation with several experts (as notably Dr. P.-O. Mojon). The Swiss Committee on Stratigraphy also validated the formal proposal for the subdivision and naming of this stratigraphic interval by Dr. A. Pictet in 2020 and 2021. Simultaneously to the work mentioned above, Eric De Kaenel, Pierre-Olivier Mojon and Antoine Pictet (De Kaenel et al., 2020) published a first local study, where Dr. A. Pictet’s conception of the lithostratigraphic succession is not considered, both because it was not the main topic of this article and because of growing discrepancies in their respective approaches on the “Urgonian” problematic. Their collaboration formally ended after the publication of this article. By completion of Dr. A. Pictet’s synthetic manuscript in spring 2021, the author took however again contact with Dr. P.-O. Mojon to invite him for a co-authorship. Although Dr. P.-O. Mojon did not reject this proposal, his reply and the heavy reconsideration requested for the proposed scheme and interpretation made it clear that a co-authorship was not possible.

Since the publication of a revised lithostratigraphic scheme for the Cretaceous deposits of the Swiss and French Jura at the formation level (Strasser et al., 2016), it became clear to Dr. A.

Based on extensive personal field and laboratory work the author already outlined a new scheme in 2017, which was progressively consolidated as new data kept on accumulating and through consultation with several experts (as notably Dr. P.-O.

The original article can be found online at https:// doi. org/ 10. 1186/ s00015-021-00395-5. The caption of figure 2 must be completed as follows: Fig. 2: Ammonite zones according to Reboulet et al. (2018) and biostratigraphic distribution of main fossil groups in the Hauterivian-Barremian series of Jura Mountains, the macrofossils were collected by the author or from museum collections. The data of the ostracod species and their extensions are based on Oertli (1989), Pasquier et al. (2013) and Strasser et al. (2018) for the Hauterivian series; on Clavel et al. (1994), Sauvagnat et al. (2001), Pasquier et al. (2013), Mojon et al. (2013), De Kaenel et al. (2020 and Eichenberger et al. (2020) for the Bôle and Rivière members, and on Pictet et al. (2019) for the Bellegarde Bed.
Dr. P.-O. Mojon draws attention to additional information unknown to the author: i. Protocythere triplicata (Roemer, 1841) is present until the "basal Aptian" (Vauglène Beds) according to Sauvagnat (1999); ii. Bairdia aff. acuminata Wilkinson, 1988as cited in Sauvagnat et al. (2001) is an invalid species name ("junior secondary homonym") reported from the Palaeozoic (Carboniferous) species Bairdia acuminata Cooper, 1946 of North America, therefore completely unrelated with the Early Cretaceous of Europe and whose author is not Wilkinson (1988); iii. Strigosocythere? reticulata is a younger synonym of Sauvagnat (1999) for the very important biostratigraphic marker Strigosocythere chalilovi (Kuznetsova, 1961) as clearly reported and indicated by Babinot and Colin (2011, p. 742), and the stratigraphic extension of the species extends only from the top of the Bôle Member (Eichenberger et al., 2020;De Kaenel et al., 2020) and in the Rivière Member (Strigosocythere? reticulata according to Sauvagnat et al., 2001) to the Vauglène Beds of the Perte-du-Rhône Formation further up (Pictet et al., 2019); iv. Most of the ostracods of the Vauglène Beds listed in Pictet et al. (2019) are also present in the Poet Bed, excepted Protocythere derooi Oertli, 1958.
N.B. The Poet and Vauglène beds were both originally defined in the plural form . The use of the singular form for the Poet Bed stresses its landmark character (hence with Bed rank) compared to the overlying marly levels of the Vauglène Beds (equivalent to the very informal term "couches" or "Schichten").
