This ichnocoenosis comprises bilobate and simple interface trails (Didymaulichnus cf.
The probable trace makers, arthropods such as branchiopod crustaceans, are potential producers of bilobate trails such as Didymaulichnus or unilobate trails such as Helminthopsis.
Within their "fluvio-lacustrine Scoyenia ichnofacies", component trace fossils may be described in morphologic terms as simple burrows, trackways, striate and bilobate pits, bilobate/trilobate burrows and trails, simple meniscate burrows, and vertical burrows (groups VII, VIII, X, XI, XII XIII in Tables 1 and 3).
A potential Rusophycus ichnofacies would be dominated by bilobate trails and pits and by trackways.
However, several of the ichnocoenoses they refer to (examples 6 to 9 in Table 3B) also contain additional morphotypes, namely bilobate pits, bilobate trails and/or predominant trackways, which are morphotypes these authors include as diagnostic of the Scoyenia ichnofacies.
Ichnocoenoses exemplifying the Scoyenia ichnofacies mostly contained meniscate burrows, with simple burrows, trackways, bilobate pits, bilobate trails and vertical burrows less common.
The root is massive and bilobate, with very short, rounded, highly diverging lobes.
The root is robust and bilobate, with very short, rounded, asymmetrical lobes.
The root is bilobate with short, rounded diverging lobes.
The root is bilobate with short, widely diverging sub-rectangular lobes.
It is highly bilobate with a thin attachment surface and a wide, shallow nutritive groove.
The root is bilobate with short, rounded lobes (the mesial lobe may be slightly longer).
