       Due to the incomplete remains not a lot is known about this dinosaur other than it is probably a basal titanosauriform. The genus name is a reference to the appearance of the tail vertebrae while the species name of R. cooneyi is in honour of J. P. Cooney who owned the land where the fossils were found.
       Other dinosaurs that possibly shared the same habitat as Rugocaudia were the nodosaur Sauropelta, the ornithopod Tenontosaurus and the dromaeosaur Deinonychus.
