This index species appears associated with conodonts. Erismodus cf. quadridactylus is the most representative species among the recovered conodonts and it is the only autochthonous conodont in the assemblage. E. cf. quadridactylus determines the age of the outcrop as well the icnoespecie Phycodes flabellum as late Darriwillian/early Sandbian.
