Fig. 10 in Palaeobiology and evolutionary context of Angulithes mermeti, a streamlined early Late Cretaceous shallow-water nautiloid

Fig. 10. Palaeoecology of the hercoglossid nautiloid Angulithes mermeti (Coquand, 1862). A. Reconstruction of A. mermeti (Coquand, 1862) in the lagoonal shallow-water environment of the Galala Formation (background after a subaqueous photograph in the property of MW from a lagoonal site in the present-day Red Sea near Hughhada taken in 1999, treated by greyscale-filtering in Photoshop CS2); rudist illustrations from Mitchell (2002). B. Bioclastic rudist (r) floatstone, the lagoonal host sediment in which A. mermeti has been found in the Wadi Ghonima section (thin-section photomicrograph of sample 080217-18). C. Close-up of Fig. 9B showing the bioclastic packstone matrix in detail, including numerous fragments of dasycladalean algae (gr).
