Mystery markings
Here are two unusual examples of the ammonite Lytoceras from the Belemnite Stone Band. Notice they have the occasional large flanges (ridges) on the shell – no-one is quite sure what purpose they serve or why they should be so prominent on this genus of ammonite. But this is one of the great things about geology and fossils: there are still lots of unresolved mysteries and new discoveries to be made.
