Deltapodus
Deltapodus is an ichnogenus of footprint produced by a stegosaurian dinosaur According to the main Stegosauria article:

"Purported stegosaurian dermal plate was reported from the latest Cretaceous (Maastrichtian) Kallamedu Formation (southern India); however, Galton & Ayyasami (2017) interpreted the specimen as a bone of a sauropod dinosaur. Nevertheless, the authors considered the survival of stegosaurians into the Maastrichtian to be possible, noting the presence of the stegosaurian ichnotaxon Deltapodus in the Maastrichtian Lameta Formation (western India).". It is known from the Lourinhã Formation of Portugal, Spain, from the Tugulu Group China, Morocco, United Kingdom and Tirgan formation Iran 

Deltapodus includes three ichnospecies: D. ibericus, D. curriei, and D. brodricki. It has been suggested that Deltapodus curriei may be registrations by Wuerhosaurus stegosaurs. See also
