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.
