Facies with Vermetids

Description (English)

Vermetids are sessile gastropods which develop near the middle level of the sea. These organisms, associated with the Neogoniolithon brassica-florida calcareous algae, build up organogenous formations in three shapes:
- The cornice or rim form: below the middle level of the sea on a subvertical rocky slope. In the north-western Mediterranean, these formations are covered with the Neogoniolithon brassica-florida and Lithophyllum byssoides calcareous algae.
- The atoll form: observed in the eastern Mediterranean (Israel and Crete), and in the Bermudas. These are rounded structures, depressed in the centre.
