Description: | Specimen of a fossil ammonite, Kosmoceras phaeinum, collected from unspecified rocks of Late Jurassic, Callovian age.
Kosmoceras phaeinum was an ammonite that lived approximately 160 million years ago. Although ammonites became extinct 65 million years ago, the same time as the dinosaurs, they probably looked very similar to the modern Nautilus that lives in the Pacific Ocean. This ammonite is unusal because it has lappets (thin rectangular projections) on its shell. You can only see one lappet (there would have been two).
It is from the Jurassic period (206 - 144 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Cephalopoda Classification: Animalia Invertebrata Ammonoidea Mollusca | Temporal: | Jurassic period (206 - 144 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
