Ichnological analysis at the Pakhna Formation (Miocene, Cyprus) reveals, for the first time, the presence of graphoglyptid structures. The Pakhna Formation is dominated by pelagic/ hemipelagic sediments, together with contourite, reworked turbidite and turbidite facies. Thus, a complex interaction between pelagic, bottom-current and gravitational sedimenta-tion is envisaged. The discernment of facies is sometimes difficult, based principally on stratigraphic and microfacies features. The record of Helminthorhaphe as a component of the graphoglytid group supports the presence of turbidites, facilitating their differentiation from the other facies. Nereites ichnofacies, punctuating a dominant/background Zoophycos ichnofacies, would reflect changes in paleoenvironmental conditions. This record offers significant perspectives to advance in the study of bottom-current and gravitational processes through outcrop examples.
