Ruopodosaurus

Arbour et al. 2024

Ruopodosaurus is an ichnogenus of ankylosaurian dinosaur footprint. The ichnogenus contains a single ichnospecies, Ruopodosaurus clava, described in 2025 from prints found in the Late Cretaceous Dunvegan and Kaskapau formations of Canada. Additional prints from the similarly aged Jindong Formation of South Korea were later tentatively referred to this ichnogenus. Ruopodosaurus represents the first recognized ankylosaurid tracks in the trace fossil record.
