    As with the adult this has more costae than any other brachiopod found in this formation. In this case 32. and 5 of them on the fold. 

    The fold and sulcus are not yet very noticeable, as this species only develops a noticeable fold as it matures.

    Very nice... unless you're trying to pass off a crisp from the Ruffles Member of the Sofa Cushions Formation: images?q=tbn:ANd9GcRVN8tatEoMzSPty02qMFG

    It's a juvenile Ruffle from down the back of the sofa.
