GAULT AMMONOIDEA
Euhoplites sp.
two pathological specimens from the Middle Albian (Lower Gault Clay) of Folkestone, Kent, UK
Specimen 1
Scanned from four positions: (1) lateral; (2) ventral adapical (note typical ventral channel of a Euhoplites from this level in the Gault); (3) ventral (you can see the point at which the damage occurs and the ventral channel disappears) and finally: (4) a ventral aspect where the ribs, albeit asymmetrical, run straight across. Notice that the direction of the ribbing on the first image changes from projecting forward up to the point of damage, reverses for around one quarter of a whorl then straightens and begins to revert to forward projecting.
