East Africa, Madagascar, Jurassic to Cretaceous period, ca. 200 to 66 million years ago. A fossilized ammonite with a ribbed shell and recessed whorl, fully excavated from the sediment with a lovely suture patterning in hues of umber and sienna brown. Ammonitic sutures are usually hidden by the material of the external shell wall, but here the wavy formations are on full display, the fractal patterning is an aesthetically pleasing and natural part of ammonite anatomy. The chamber opening is framed by carving around the suture outlines and the fossil is mounted on a block of thuya wood, the swirling graining compliments the shell. Size: 12.5" Diameter x 3" W (31.8 cm x 7.6 cm); 13" H (33 cm) on included custom stand.
