Cranial anatomy and systematics of Dendrerpeton cf. helogenes (Tetrapoda, Temnospondyli) from the Pennsylvanian of Joggins, revisited through micro‐CT scanning

A re-examination of the most complete tetrapod specimen from Joggins Fossil Cliffs, using micro-CT scanning, reveals that the genus Dendrysekos is a junior synonym of Dendrerpeton, resolving a long-standing taxonomic question. The study identified previously obscured anatomical structures, including the stapes and scleral plates, which were critical in redrawing the boundaries between these genera. Phylogenetic analyses, however, indicate that relationships among early temnospondyl groups remain poorly resolved due to limited shared derived characters. Joggins continues to provide invaluable insights into late Carboniferous ecosystems, particularly for its rich terrestrial fauna record.
