9.5 INCH SPHENODISCUS AMMONITE
9.5 INCH SPHENODISCUS AMMONITE. This complete 9.5 inch large 90 million year old ammonite Sphenodiscus lenticularis was found in Montana and was fossilized when the large inland sea submerged much of Montana. Ammonites were like armored squid that became extinct 65 million years ago at the same time as the dinosaurs. This beautiful example still has some of its original mother-of-pearl which has fossilized from brown to an iridescent red color. These colors are so prized that gemstones are made from them called ammolite. Interesting suture patterns (strengthened the shell) show where the mother-of-pearl has worn off. This large heavy ammonite sits upright against a solid stone matrix making for an excellent display or even for use as a book-end.
