Discovery of traces of Cruziana semiplicata and C. rugosa groups (Cambro-Ordovician) from the Lesser Himalaya, India and their stratigraphic, tectonic and palaeobiogeographic implications

Original language description

Trace fossils Arthrophycus cf. A. brongniartti, Asterosoma ludwigae, Bergaueria perata, Cruziana semiplicata, Cruziana furcifera, Curvolithus simplex, Diplichnites gouldi, Monomorphichnus lineatus, Phycodes circinatum, Phycodes palmatum, Phycodes rarus, Palaeophycus striatus, Planolites isp., Rusophycus leifeirikssoni, Rusophycus petraeus, Rusophycus latus, Rusophycus isp.-A , Rusophycus isp.-B, Rusophycus isp.-C, ?Rhabdoglyphus isp, and Treptichnus pedum are reported from the Arkosic Sandstone Member (Koti Dhaman Formation, Tal Group), Nigalidhar syncline, Lesser Himalaya. Cruziana semiplicata ranges from Furongian to early Ordovician and the trace fossils of the Cruziana rugosa group are considered as typical Ordovician in age, their presence suggests an Ordovician transgression in the Indian Lesser Himalaya and an extension of the sea from Gondwana on to the Indian plate. It implies a hiatus between the Arkosic Sandstone Member and the underlying lower Cambrian Shale Member. The contact between the two shows angular and erosional discordance. The angular discordance is related to the Cambro-Ordovician Kurgiakh orogeny event. The Ordovician trace fossil bearing Arkosic Sandstone together with overlying sequence is being separated from the Tal Group is now designated as the Deona Formation. This contribution introduces a significant facet to the evolution of the Himalaya in general and the Lesser Himalaya in particular.
