- Lot Description
North America, Alberta, Canada, upper-Cretaceous period, 70 to 75 million years ago. A huge ammolite - a fossilized shell of an extinct sea creature known as an ammonite, that is only found in the Bearpaw Formation of Alberta, Canada. This is an organic gemstone that boasts an astonishing array of iridescent colors. The brightness of this specimen's colors and the iridescence is a testament to the well-preserved state of the nacreous shell, and how orderly and fine the aragonite layers are. Please note that this fossil shows tooth marks from a Mosasaur, a large extinct marine reptile predator that was apparently hungry for an ammonite. Holes like these were once thought to result from limpets attaching themselves to the ammonites; however, their size as well as presence on both sides of the ammonite, linked them to the upper and lower jaws and the bite of medium-sized Mosasaurs. Size: 12.75" W x 10.875" H (32.4 cm x 27.6 cm); 10.25" H (26 cm) on included custom stand (piece leans back on the stand).
Ammolite is a rare, iridescent, gem-quality material cut from the fossilized shells of extinct sea creatures known as ammonites. Found only in the Bearpaw Formation in Alberta, Canada - along the eastern slopes of the Rocky Mountains, this organic gemstone has a dazzling range of colors and patterns and is highly desired for freeform natural cabochons and assembled jewelry pieces.
According to the International Gem Society (IGS) statement on the difference between Ammolite and Ammonite: "You may find the terms ammolite and ammonite sometimes used interchangeably. However, ammonite, strictly speaking, refers to the fossil shells of ammonites, whether gem-quality or not. Ammolite refers to the gem-quality material made from fossils of particular species of ammonites." Also according to IGS, "Ammonites were marine mollusks that became extinct around 65 million years ago. There were many species of ammonites, and their fossils have been found across the globe. The fossils of Placenticeras meeki, Placenticeras intercalare, and Baculites compressus can yield gem-quality ammolite. To date, this material has been found only in Alberta, Canada."
The etymology of Ammonite according to International Gem Society: "From ammonite, the fossils of an extinct cephalopod with a spiral shell like a ram's horn. Ammonite was named after the Ancient Egyptian god Amun, who was represented with ram's horns."
Accompanying label states, "Ammolite Bitten by Mosasaur / 71 million years old / Bear Paw Formation, Blood Indian Reserve, St. Mary River, Alberta Canada - Beautiful Canadian Gemstone"
