. 39, fig. 1 (Stoppani, p. 244). However, the hinges are dissimilar: in the illustration, the large front hinge tooth is globose and more irregular than that of the reconstruction, and there are two parallel cardinal teeth instead of one. Stoppani (p. 244) stated that the two cardinal teeth were a bit more prominent in the drawing, but the second tooth is not even roughly delineated in the valve reconstruction. The hinge seems to correspond more to the negative relief embossed in the plaster cast of the internal mould. A number ‘2.’ is engraved at the centre of the interior surface of the valve: what this refers to is unknown.

. 39 were ‘adapted’ by the author to show what he thought was their original appearance. In particular, the large cardinal tooth is not globose as in the reconstruction, and only one cardinal tooth is apparent. In the plaster cast of the mould, the left valve has an impression left by a possible second, not very evident, tooth (Stoppani emphasized that the two teeth in the drawing were ‘exaggerated’) and a spherical cavity that corresponds perfectly to the globose cardinal tooth. Clearly, the decisions made by Stoppani when recreating the hinge were driven by the characteristics of the traces present in the mould of the left valve. Both valves were drawn as mirror images of each other, whereas Maestri’s reconstruction matched the original conformation.
