Abstract
The ichnogenus Avetoichnus and the corresponding type ichnospecies Avetoichnus luisae Uchman & Rattazzi, 2011 were first described based mainly on specimens from Alpine (Italy) and Carpathians (Poland) deep sea realm as complex trace fossil, horizontal and sub-horizontal, with a helical spiral string around a simple core, which can be straight or slightly curved. Ethologicaly, is interpreted as agrichnion generated by non-graphoglyptids belonging to Nereites Ichnofacies. In this paper is presented the occurrence of Avetoichnus luisae in Eocene sediments from red and green shale member of Bisericani Formation from Vrancea Nappe, Bistrita halfwindow, Eastern Carpathians. The studied specimens reveal a close relationship with shallow water deposits, Cruziana Ichnofacies, possible characterized by isolated depletion in nutrients that could induce farming behavior of the producer.
