Note. Menisci of T. serpentinum Heer (1877) are much more widely spaced.
Chen, Z.-Q. et al., 2012
Taenidium is indicated by unlined, straight or slightly curved to sinuous burrows that contain segmented filling (Figs. 6D, H–K, 8 F, 11B). Burrows also have well-spaced arcuate menisci but lack walls. The annular ornamentation is rather pronounced and the burrow may be slightly flanged at one end. These traces have a width of 3–4mm and length up to 24 mm with partitioned packeting. All features observed here agree with the type ichnospecies T.serpentinum Heer.
