(Misspelled as Camplodoniscus) Maxilla with teeth. This form is based on an incomplete maxilla from the Late Cretaceous of Argentina (Huene,1929). It contained teeth with spatulate crowns broader than those of the diplodocids but not as broad as those of the camarasaurids and quite different from the tiny slender teeth of Antarctosaurus and also those assigned to Alamosaurus (Kues et al. 1980) 

In a second maxilla (Huene and Matley,1933) from the Late Cretaceous of India, the teeth are missing, however the element is high and robust, as in camarasaurids. Because of the incompleteness of the two maxillae, they cannot be compared critically and may be in no way related.
