Rhynchosauroides is an ichnogenus, a form taxon based on footprints. The organism producing the footprints was likely a lepidosaur^[1] and may have been a sphenodont, an ancestor of the modern tuatara. The footprint consists of five digits, of which the fifth is shortened and the first highly shortened.^[2]
