The carbonate strata of the Burdigalian Guri Member are located in the Dezful Embayment along the northern Persian Gulf shore. Ichnofabric analysis and paleoecology of the Guri Member in the Dezful Embayment are described by investigating three outcrop sections. The facies features of the Guri Member show a very shallow marine environment with high oxidation content. The Guri Member contains remarkably well-preserved specimens of Thalassinoides suevicus. It is mainly recorded as Y and T forms in the shallow water facies. Two ichnofabrics were recognized in the dominantly carbonate sedimentary succession. Ichnofabrics A, and B are interpreted as representing the tidal flat and lagoon environments respectively. Ichnofabric interpretation of the Miankuh section might be simply indicating more time to colonization in relation to the Parsi section. Keywords: ichnofabric, Miocene, Dezful Embayment, Guri Member.
