 The main fossil find of a Paleocene ammonoid is a scaphitid ident from Turkmenistan.In medieval Europe, fossilised ammonites were thought to be petrified coiled snakes, and were called "snakestones" or, more commonly in medieval England, "serpentstones".They were considered to be evidence for the actions of saints, such as Hilda of Whitby, a myth referenced in Sir Walter Scott's "Marmion", and Saint Patrick, and were held to have healing or oracular powers.
