Though Late Cretaceous stegosaurian fossils have been reported, these have mostly turned out to be misidentified. A well-known example is "Dravidosaurus", known from Coniacian fossils found in India. Though originally thought to be stegosaurian, in 1991 these badly-eroded fossils were suggested to instead have been based on plesiosaurian pelvis and hindlimb material, and none of the fossils are demonstrably stegosaurian. The reinterpretation of "Dravidosaurus" as a plesiosaur wasn't accepted by Galton and Upchurch (2004), who stated that the skull and plates of "Dravidosaurus" are certainly not plesiosaurian, and noted the need to redescribe the fossil material of "Dravidosaurus". A 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).
