New Middle Cambrian palaeoscolecid sclerites of Hadimopanella oezgueli from the Cantabrian Mountains, northern Spain

A new assemblage of palaeoscolecid sclerites preserving all the details of the (para)species Hadimopanella oezgueli Gedik, 1977, including characteristic ornamentation, has been found in the Middle Cambrian Genestosa Member (Oville Formation) of the Cantabrian Mountains, northern Spain. The assemblage of sclerites shows a great morphological variability enabling emendation of its diagnosis. Some of them exhibit erosive facets as a result of reworking preceding definitive burial. One key specimen has lateral slits along the marginal brim, which represent a crown of eroded tubercles, and may be classified out the (para) genus Hadimopanella.
