FIGURE 5 Upper offshore sandy mudstones containing ichnological suites consistent with the
archetypal expression of the Cruziana Ichnofacies. (A) BI ¼ 5, with Zoophycos ( Z ), Planolites ( P ),
Asterosoma ( As ), Diplocraterion habichi ( Dh ), Chondrites ( Ch ), Cosmorhaphe ( Cr ), Phycosiphon
( Ph ), and Thalassinoides ( Th ). (B) BI ¼ 4, with a remnant, wavy parallel-laminated sandstone
bed interpreted as a tempestite. Trace-fossil suite consists of Planolites ( P ), Chondrites ( Ch ),
Diplocraterion habichi ( Dh ), Phycosiphon ( Ph ), Schaubcylindrichnus freyi ( Sf ), Zoophycos ( Z ), and
Teichichnus ( T ). (C) BI ¼ 5 with Cosmorhaphe ( Cr ), Planolites ( P ), Chondrites ( Ch ), Palaeophycus
heberti ( Pa ), Phycosiphon ( Ph ), Zoophycos ( Z ), and Asterosoma ( As ). (D) BI
4, with a remnant,
parallel-laminated sand bed interpreted as a tempestite. Trace-fossil suite includes Siphonichnus
( Si ), Planolites ( P ), Chondrites ( Ch ), Teichichnus ( T ), Phycosiphon ( Ph ), Thalassinoides ( Th ), and
