Figure 5.
Skolithos(?) burrows (arrows) from intraclast host facies (diagenetic iron staining accentuates burrow) (A) and cutting intraclast margins (B) (solid arrows—burrows; open arrows—edges of intraclasts). (C–D) Branched burrows with similar relationships. Burrows that cross intraclast margins demonstrate that the cementing agent was no longer present after the clast was buried by sand in the swash zone but was still within reach of Cambrian shallow-depth burrowers.
