Pyrodendrina Tapanila, 2008

Type ichnospecies

Pyrodendrina cupra Tapanila, 2008, by original designation and monotypy.

Original diagnosis

Dendrinid boring system with shallow and deeply penetrating canals that radiate away from a central polyhedral node. Shallow canals are dominantly horizontal and may bifurcate. Deeply penetrating canals extend vertically in straight to slightly curved path and may bifurcate.

Emended diagnosis

Dendrinid boring system in calcareous skeletal substrates, with shallow and deeply penetrating canals that radiate away from a central node. Shallow canals dominantly horizontal and may bifurcate. Deeply penetrating canals extend vertically in a straight to slightly curved path and may bifurcate.

Remarks

Pyrodendrina is the only known rosetted boring to have deeply penetrating distal canals, and this feature is a primary ichnotaxobase for the ichnogenus.
