Trace fossils and ichnofabric across the Volkhov depositional sequence (Ordovician, Arenigian of St. Petersburg Region, Russia).

Popis výsledku v původním jazyce

Ichnofabric (bioturbation and bioerosion) patterns show a conspicuous symmetry across the Volkhov depositional sequence, which suggests a close relationship between the ichnofabric and the sea-level change. Bioclastic limestones interpreted as calcareoustempestites show evidence of relatively deep bioturbation (ca. 15 cm) of high intensity. Ichnogenera Thalassinoides, Chondrites, Paleophycus,? Dolopichnus, Trypanites, Gastrochaenolites and Planolites participate for the most part in the overall substrate disturbance. Intensive deep bioturbation and even bioerosion occurs in the studied area even below the recently re-interpred Early Middle Ordovician boundary. This observation suggests that diverse boring strategies and deep bioturbation, as well as other modern features (e. g. Complex tiering re-visiting of filled burrows), first appeared during the early ordovician in this region.
