Description

SUPERB AMMONITE
Perisphinctes sp.
Jurassic, Oxfordian Stage
Madagascar
This lovely ammonite from Madagascar has it all: fully prepared on both sides it retains superb three-dimensionality to the ribbed, coiled form and boasts a good expanse of the original shell covering in a chalky white, almost opalescent, coloring. Where the shell is lacking, however, one is afforded a fascinating view of the inner structure, the characterful growth patterns forming fern-like markings in lovely soft shades of brown and cream, and the shell itself terminates in the three-dimensional bronchiate forms of this sutured growth. A lovely example of a beautiful and classic fossil, it measures 9¼ inches in diameter and is well-presented on a metal display stand.
