Benefits and limits of x-ray micro-computed tomography for visualization of colonization and bioerosion of shelled organisms

This paper records a new sessile cirripede from a nearshore, shallow-water facies at Předboj near Prague, Czech Republic. The new taxon, Archaeochionelasmus nekvasilovae gen. et sp. nov., is the earliest known neobalanoform barnacle, and while it may have been an obligate commensal of a cephalopod or marine reptile, that it was a shore barnacle cannot be ruled out.
