Abstract

In 1990, a hypotype of the ichnospecies Dromillopus quadrifidus Matthew, 1905 was discovered preserved as a cast in a rockfall of fine-grained Pennsylvanian (Westphalian B) sandstone at Joggins, Nova Scotia. The hypotype of this tetrapod trackway, while possessing all the morphological features evident in the holotype, is about five times larger. It also exhibits relatively subtle salamandroid affinities, thus helping confirm the original assignation. Minimum length of the adult amphibian trackmaker is estimated at 20 cm.
