xraymike79 posted a topic in Member Collections94mm Dactylioceras tenuicostatum prepared inside a geode. Tenuicostatum zone, Early/Lower Toarcian (183.0 - 182.0 Mya) Kettleness, North Yorkshire, UK I bought this from a well known collector named Anders Grube in Germany.
This species gives its name to the zone and subzone at the bottom of the lower Toarcian. This very fine-ribbed specimen of the genus Dactylioceras is for me a fine representative for the legend of St. Hilda, the Abbess at the monastery in Whitby ca. 650 A.D. She wanted to build a convent there as well, but the grounds were infested with snakes, so she prayed so intensively that all of the snakes were turned into stone. Since then they are known as snakestones. I found this sample pretty well as is with a head that reminds us of a snake. Literature: Howarth, M.K.
