Fig. 4From: Boring bivalve traces in modern reef and deeper-water macroid and rhodolith bedsSlab surfaces of Moorea algal nodules (< ~ 2 m water depth) showing encrusting (en) and fruticose (fr) coralline growth forms and the boring bivalve traces (G, Gastrochaenolites). Within the algal nodules, serpulids and encrusting/arborescent foraminifera (min, Miniacina; hr, Homotrema) are present. Note that most of the nodules consist of coral fragmentsBack to article page
