Description
**Originally Listed At $650**
Ancient Seas, North America, South Dakota, Pennington County, Cheyenne River, Pierre Shale Formation, Cretaceous Period, ca. 83.6 to 72.1 million years ago. A collection of fossilized shell fragments from baculite cephalopods, a type of heteromorph ammonite with a straight rather than spiraling shell. Included are 13 pieces that have interesting fern like suture patterns and pearlescent hues. These columnar structures are the outer layers from the shell that protected the soft tissues of the animal inside- their tentacles reaching out from the wide chamber opening - perfectly exemplified by the included drawing. All are mounted with copper wires on a felt and wood frame as a great educational and display piece. Size (largest fossil): 7" L x 2.25" W (17.8 cm x 5.7 cm); (frame): 20.5" L x 17" W (52.1 cm x 43.2 cm)
Provenance: private New Jersey, USA collection
All items legal to buy/sell under U.S. Statute covering cultural patrimony Code 2600, CHAPTER 14, and are guaranteed to be as described or your money back.
A Certificate of Authenticity will accompany all winning bids.
