dc.description.abstractTrace fossils from the Torneträsk Formation, Dividalen Group, in northern Sweden indicate that most or all of the succession is Early Cambrian in age. This contrasts with previous work which placed the lower part of the formation in the Vendian, a conclusion based on the occurrence of the 'medusoid' body fossil Kullingia concentrica. We report here an assemblage of Early Cambrian traces below Kullingia -bearing horizons. In addition, we report the body fossil Sabellidites sp. from the upper Lower siltstone member at the same leve! as Kullingia. Together these fossils indicate correlation with sections in Ukraine attributed to the upper part of the Rovno 'stage'. Late Early Cambrian trilobites in the uppermost part of the Tometriisk Formation occur above a dolomitic horizon with phosphatic pebbles. Below this horizon, no fossils indicative of Talsy or younger age were found, suggesting that the phosphatic leve! rnay represent a significant unconformity. The age of the oldest deposits of the Tornetriisk Formation, including the Lower sandstone member and the basal Lower siltstone member, remains uncertain, as no age-diagnostic fossils were observed. Many of the trace fossils observed in this study, including cf. Curvolithus, Treptichnus, Phycodes, and Teichichnus, exhibit a three-lobed lower surface on some of the specirnens. This feature is common in Early Cambrian traces, but extremely rare in younger deposits, suggesting that it represents a signiticant but unknown group of Early Cambrian burrowing animals.es_ES
dc.description.sponsorshipWe gratefully acknowledge financial support forfieldwork from Uppsala University (Liljewalchs and Lennander stipends). The staff of the Royal Swedish Academy Research Station at Abisko provided a pleasant working atmosphere. Jensen's research in Cambridge is supported by a grant from the Leverhulme Trust. We thank Reinhard Greiling, Malgorzata Moczydlowska, Simon Conway Morris, and the late Gonzalo Vida! for critical readings of earlier manuscript versions. Luis Buatois, Gabriela Mangano and Radek Mikulås k.indly provided access to their paper in press on Curvolithus. Helpful criticism and suggestions of the reviewers Richard G. Bromley and Frederik Bockelie improved the paper. This is Department of Earth Sciences publication no. 5057. We dedicate this paper to the memory of Gonzalo Vidal.es_ES
