Description:

East Africa, Madagascar, Jurassic to Cretaceous period, ca. 200 to 66 million years ago. A superb, fossilized ammonite that is fully excavated from the sediment with a lovely ammonitic suture patterning in hues of umber and sienna brown. Sutures are usually hidden by the material of the external shell wall, but here the wavy formations are on full display, the fractal patterning or suture marks are an aesthetically pleasing natural part of ammonite anatomy and their shapes can help determine species and even time period of existence! Size: 7.7" L x 1.9" W x 5.7" H (19.6 cm x 4.8 cm x 14.5 cm)

Provenance: private Constance McCormick Fearing estate, Montecito, California, USA, acquired before 2004
