Abstract: Trace fossils from the outcrop section of the Enugu Formation in Anambra Basin, southeastern Nigeria, have been studied based on the varieties, types, mode of occurrence, orientation of the burrows, wall structures and fills. Five ichnogenera identified belong to the Skolithos and Cruziana ichnofacies and include; Skolithos isp. Thalassinoides isp., Planolites isp., Teichichnus isp. and Chondrites isp. The assemblage is suggestive of deposition in a nearshore setting influenced by stressed environmental conditions due to the mixture of marine and fresh water inflows. The lithologic characteristics, physical sedimentary structures, the distribution and the style of the bioturbation from the base to the top of the sequence, as well as the general absence of deeper marine ichnofacies suggest moderate to high energy conditions in a prograding shoreline and shallow marine environments.
