Description
Cylindrical burrows with distinct stuffed structure, mostly branched, typically forming an umbellated, 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 (see p. W75, W84) but commonly smaller. [Taenidium was originally interpreted as alga (see LORENZ VON LIBURNAU, 1900, p. 528-567), but originates in feeding burrows by periodic filling of tunnel in backward direction; it occurs in wide range of environments. Stuffed burrows have been discussed by RICHTER in WILCKENS (1947, p. 4445) and by TOOTS (1967).]
