Strigoceras pseudostrigifer Maubenge 1955.
Strigoceras are thought to have been very fast swimmers. One reason for this is the series of fine lines and grooves (strigations) running the length of the shell. This specimen shows these to perfection on one surface.
Jurassic, Bajocian, Inferior Oolite.
