Elasmaria is a clade of iguanodont ornithopods known from Cretaceous deposits in South America, Antarctica, and Australia.[1][2]
Classification
Calvo et al. (2007) coined Elasmaria to accommodate Macrogryphosaurus and Talenkauen, which they recovered as basal iguanodonts distinct from other iguanodontians in having mineralized plates on the ribs.[3] Later, the putative Gondwanan hypsilophodonts Atlascoposaurus, Notohypsilophodon, and Qantassaurus were recognized as being distantly related to Hypsilophodon and instead belonging to Elasmaria.[4]
