Ammonite - Fossilised Specimen
Well preserved example of an uncurled Ammonite. Whilst most ammonites are enrolled (homomorph), a major group of ammonites emerged during the late Jurassic that had uncoiled shells, and these are known as heteromorph ammonites.
This animal lived during the Jurassic and Cretaceous periods of Earth's history at least 66 million years ago. Ammonites became extinct at the end of the Cretaceous Period at approximately the same time that dinosaurs vanished.
