(A) Bedding-plane view with Paleodictyon . (B) Bedding plane with Taphrhelminthopsis (
Scolicia
strozzii) . (C) Bedding plane with Spirorhaphe . (D) Bedding plane with Nereites . (E) Muddy sand-
stone (BI ¼ 5) with a suite consisting of Chondrites ( Ch ), Zoophycos ( Z ), Spirophyton ( Sp ), and Cos-
morhaphe ( Cr ). (F) Sandy mudstone (BI ¼ 5) with a suite consisting of Spirophyton ( Sp ),
Cosmorhaphe ( Cr ), and Phycosiphon ( Ph ). Scale in B is 5 cm long; all other scales are 3 cm long.

Figure 4—cont'd (D) Bioturbated muddy sandstone (BI
5) with a suite consisting of Scolicia ( Sc ),
Thalassinoides ( Th ), Schaubcylindrichnus freyi ( Sf ), Phycosiphon ( Ph ), Palaeophycus heberti ( Pa ),
Chondrites ( Ch ), and Asterosoma ( As ). Scales are 3 cm long. NB: Recent ichnotaxonomic work sug-
gests that structures identified as Cosmorhaphe in this chapter are better regarded as Nereites mis-
souriensis (e.g., Angulo and Buatois, 2012 ).
