Ammonite remains from the Maastrichtian of continental Greece. a, b Slab and counterslab showing the dark remains of ammonitin upper jaws; SGL1_4b, a; note the small jaw on the bottom left in b. c Intermediate type of lower jaw, with both valves; SGL1_38. d ?Lissaptychus sp., with both valves; SGL1_40. e Poorly preserved ammonite conch (AND2_1) of a desmoceratoid, possibly of ?Kitchinites sp.; the body chamber is thicker than the phragmocone, which is heavily recrystallized. f ?Hauericeras sp.; SGL1_36; note the evolute conch lacking ornament and the biconcave aperture; the siphuncular tube of the last two whorls of the phragmocone are preserved. The brownish lobes on the right are calcitic dendrites, i.e. secondary formations linked to weathering and small-scale karstification. B, ammonite lower aptychus-type jaw, probably Striaptychus
