Key Facts & Value
Key Fact
Description
This is a fossilized ammonite, a marine mollusk that lived millions of years ago. The specimen displays a distinct spiral shape, characteristic of its species. The exterior of the shell is textured with ridges, and the internal structure is partially visible, revealing the chambers of the creature's past home. It appears to be a light, sandy-colored stone with hints of blue-grey discoloration. The fossil measures approximately four inches in diameter.
History
Ammonites are extinct marine cephalopods that were abundant during the Mesozoic Era, from the Jurassic period to the end of the Cretaceous period. They are related to modern-day squid and octopus, but their shells are more similar to that of a Nautilus. The fossil record of ammonites is extensive, providing valuable insights into prehistoric marine life and the history of the Earth.
Facts
Ammonites are popular among fossil collectors and paleontologists alike for their beautiful preservation and evolutionary significance. Their coiled shells served as protective homes and buoyancy regulators. The variety of ammonite shapes and sizes is astounding, with some species reaching up to two meters in diameter. Their extinction coincided with that of the dinosaurs, marking the end of an era.
Value Fact
Ammonite fossils vary greatly in price depending on size, preservation quality, and rarity. Smaller, common specimens can be found for as little as $10-$20. Larger, exceptionally well-preserved, or unusually patterned ammonites can fetch hundreds or even thousands of dollars. Demand is driven by collectors, decorators, and educational institutions.
