Onychites from Polish Jura and Their Functional Morphology

<i>Onychites</i> aff. <i>barbatus</i> is excessively rare in the Polish Jura. This paper describes a recent find from the basal middle Oxfordian. The specimen is preserved in a manner typical for other finds of this kind in platy limestones, i.e., as compressed and flattened...
