31. Ichnogenus: Maeandropolydora Voigt, 1965 Ichnogenus: Sulcichnus n. ichngen. DIAGNOSIS: Long grooves having two or more apertures running through the surface substrate sinuously or contorted.Grooves never runs in parallel and loose or tight loops may occur. Type species: Sulcichnus maeandriformis Other species: Sulcichnus helicoidalis Sulcichnus sigillum DIAGNOSIS: Long cylindrical galleries having two or more apertures, running through the substrate sinuously or in irregular contortions. Ga- lleries may run parallel in contact with each other in pairs, with or wi- thout fusion. Loose or tight loops may occur; the limbs of these maybe connected by a vane or form a pouch. (Bromley & D’Alessandro, 1983)
