The ichnogenus Beaconites and its distinction from Ancorichnus and Taenidium.
Likewise, an interpreted "single community" approach is not a valid criterion even though the 10-20 mm wide Taenidium barretti of TF35a occur stratigraphically subjacent to suite TF36a (ichnocoenosis E) that contains Hexapodichnus horrens tracks of similar width.
This ichnocoenosis comprises simple unbranched burrows (Planolites beverleyensis, Taenidium barretti) and rare systematically branched burrows (Phycodes pedum Seilacher), together with vertebrate trackways (types D and E of Keighley and Pickerill 1998).
The large Taenidium barretti of TF28a was also produced after the flood deposit.

Trace fossils include Skolithos, Taenidium, and broad Arenicolites.
