| W. Hantzschel 1975 | Cylindrical burrows with distinct stuffed structure, mostly branched, typical Taenidium (T. fischeri, Heer) unbellated, rootlike system of burrows radiating downward; burrows with transverse segmentation reminiscent of “Orthoceras”; segmentation may also be observed on outside as annular constrictions; similar to Keckia Glocker and (partim) Muensteria Von Sternberg but commonly smaller. |
