Diagnosis Bioerosion trace in calcareous skeletal substrates with a tubular, straight to arcuate entrance tunnel leading to a prostrate plexus of ramifying or anastomosing galleries, forming up to a semicircle to one side of the point of entry. Etymology Latinised from the ancient Greek ‘ρóπαλον’ (rhopalon), club, and ‘δένδρον’ (dendron), tree, referring to the club-shaped widening of terminal galleries in the type ichnospecies, and acknowledging the corresponding informal naming of the Rhopalondendrina-Form by Ingrid Glaub (1994) . Remarks Distinguished from Nododendrina by the lack of a vertical node below the point of entry and from Abeliella by the differing principle substrate type . Distinguished from all other dendrinids by the presence of the tubular entrance tunnel and/or the general outline of the plexus.
