Abstract ref. 2026:
On the eastern coast of Sardinia, in the Siniscola-Posada area, Jurassic rocks are transgressive on the Hercynic basement. The sequence begins with 15 to 50 metres of dolomitic limestones and dolostones, yielding Bathonian and Callovian ammonites. Oxfordian is probably missing. The middle Jurassic dolostones are directly overlaid by Kimmeridgian limestones, 100 m thick. The Beckeri zone is well represented in their upper half, with the index form and several other ammonites and aptichi. The Jurassic sequence ends with Tithonian limestones in reef facies.
