Eudmetoceras aff. eudmetum (Buckman, 1920)

18cm. Another rarity for this site. It is now assumed that this and other related forms are the forerunners of many Bajocian ammonites such as the Sonninia, since the Graphoceratidae died out at the end of the Aalenian.

Found in the Concavum Zone, Upper Aalenian, Middle Jurassic of the clay pit in Geisingen.
