Highly bioturbated beds in small sedimentary outcrops have been reported, for the first time, from two localities near the Gedaref town. The trace-bearing beds are medium-to fine-grained sandstones associated with mudstones, assuming a coarsening upward sequence. The trace fossils were identified as Thalassinoides isp. and Skolithos ichnofacies association namely: Skolithos, Monocraterion, Diplocraterion and Conichnus isp. Based on the aforementioned litho and biofacies associations, the studied sediments might have been deposited in a more distal facies of a fluvial system, most probably in a deltaic environment.
► Trace fossils were discovered at two localities near the Gedaref town. ► The bioturbated beds were encountered at the top of the Gedaref Formation. ► They include Skolithos ichnofacies and Thalassinoides isp. ► The studied beds could have been deposited in a deltaic environment.
