FIG. 6 in Rudist-bearing rhodalgal facies in the post- Turonian recovery of peri-Tethyan carbonate systems: a case history from the Nurra region (northwestern Sardinia, Italy)

FIG. 6. — Nurra region, northwestern Sardinia; A, Capo Caccia section: small algal nodule in Santonian rudistid limestone with rhodalgal assemblages; the rhodolith is sub-spheroidal and shows lumpy and fruticose outer growths; B, Punta Negra section: small algal nodules in a gravity deposit of which the plankton-bearing matrix includes plankton. It also contains non-geniculate red algae and bryozoan fragments. The rhodolith is sub-spheroidal and shows lumpy and fruticose outer growths; C, D, Uri section: coralline algal debris with lumpy rhodoliths and fragments of fruticose corallines in reddish-pink marly resedimented deposits with bauxite fragments (bx), relict rhodalgal components and planktonic foraminifera. Scale bars: C, D, 2 cm.
