The Paleocene to Middle Eocene Tarcau Sandstone at Buzau Valley, eastern Carpathians, Romania, records sedimentation in a turbidite system. These strata contain a diverse and abundant pre- and postdepositional ichnofauna consisting of 35 ichnogenera and 54 ichnospecies. The predepositional assembalge is rich in graphoglyptids and ornate grazing trails; simple grazing trails, resting traces, and feeding structures also occur. The postdepositional association essentailly consists of dwelling, feeding, and grazing traces. Elements of the Skolithos ichnofacies are present not only in the most proximal parts of the turbidite system, but also in distal parts. The number of predepositional forms greatly exceeds postdepositional ones, reflecting a predominance of K-selected over r-selected population strategies in a stable environment. This abundant and diverse Eocene ichnofauna supports the idea of extremely rich deep-sea ichnofaunas in the Cenozoic.
