Microsolenid laminar framework reefs with stromatolitic crusts (with clotted micrite and microspar). Corals encrusted by coralline and peyssonneliacean red algae, encrusting foraminifers, and stromatolitic crusts.
Microbes 20% of reef volume. 
Burrows in semi-consolidated stromatolites interpreted as borings by me.
Microborings present
