    • Life through an Ediacaran glaciation: Shale- and diamictite-hosted organic-walled microfossil assemblages from the late Neoproterozoic of the Tanafjorden area, northern Norway 

      Agic, Heda; Jensen, Sören; Meinhold, Guido; Högström, Anette Elisabeth Sofi; Ebbestad, Jan Ove R.; Høyberget, Magne; Palacios, Teodoro; Taylor, Wendy L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-05)
      New organic-walled microfossil (OWM) assemblages are reported from upper Neoproterozoic glacial and interglacial siliciclastic deposits in Finnmark, northern Norway. A nearly continuous sedimentary succession of the Vestertana Group contains two glaciogenic units, the Smalfjorden and Mortensnes formations, interpreted as end-Cryogenian Marinoan and Ediacaran glaciations, respectively. We investigated ...

    • A new interpretation of the sedimentary cover in the western Siljan Ring area, central Sweden, based on seismic data. 

      Juhlin, Christoffer; Sturkell, Erik; Ebbestad, Jan Ove R.; Lehnert, Oliver; Högström, Anette; Meinhold, Guido (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Two new reflection seismic profiles over the Paleozoic successions of the western part of the Siljan Ring impact structure show a contrasting seismic signature. The more southerly c. 10 km long Mora profile reveals a highly disturbed structure, with only a few kilometers of relatively horizontally layered structures observed. However, interpretations of refracted arrivals in the data, that can be ...

    • New occurrences of Palaeopascichnus from the Stáhpogieddi Formation, Arctic Norway, and their bearing on the age of the Varanger Ice Age. 

      Jensen, Sören; Högström, Anette; Høyberget, Magne; Meinhold, Guido; McIlroy, Duncan; Ebbestad, Jan Ove R.; Taylor, Wendy L.; Agic, Heda; Palacios, Teodoro (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-18)
      We report on new occurrences of the late Ediacaran problematicum <i>Palaeopascichnus</i> (Protista?) from the Stáhpogieddi Formation, Arctic Norway. The stratigraphically lowest occurrences are in beds transitional between the Lillevannet and Indreelva members: the highest in the second cycle of the Manndrapselva Member, stratigraphically close to the lowest occurrences of Cambrian-type trace fossils. ...

    • Rare earth elements and neodymium and strontium isotopic constraints on provenance switch and post-depositional alteration of fossiliferous Ediacaran and lowermost Cambrian strata from Arctic Norway. 

      Meinhold, Guido; Willbold, Matthias; Karius, Volker; Jensen, Sören; Agić, Heda; Ebbestad, Jan Ove R.; Palacios, Teodoro; Högström, Anette; Høyberget, Magne; Taylor, Wendy L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-16)
      The Digermulen Peninsula in northeastern Finnmark, Arctic Norway, comprises one of the most complete Ediacaran–Cambrian transitions worldwide with a nearly continuous record of micro- and macrofossils from the interval of the diversification of complex life. Here, we report on the provenance and post-depositional alteration of argillaceous mudstones from the Digermulen Peninsula using rare earth ...

    • Scratch circles from the Ediacaran and Cambrian of Arctic Norway and the Republic of South Africa, with a review of scratch circle ocurrences 

      Jensen, Sören; Högström, Anette; Almond, John E.; Taylor, Wendy L.; Meinhold, Guido; Høyberget, Magne; Ebbestad, Jan Ove R.; Agic, Heda; Palacios, Teodoro (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-13)
      Scratch circles - bedding plane parallel sedimentary structures formed by the passive rotation of a tethered organism into the surrounding sediment - are relatively rare in the geological record. Here new occurrences of scratch circles are described from the Ediacaran-Cambrian Stáhpogieddi Formation, Digermulen Peninsula, Arctic Norway, and from the Ediacaran Nudaus and Urusis formations, Nama Group, ...
