Cetiosauridae is a family of sauropod dinosaurs. While traditionally a waste bin taxon containing various unrelated species, some recent studies have found that it may represent a natural clade.[1] Additionally, at least one study has suggested that the mamenchisaurids may represent a sub-group of the cetiosaurids, which would be termed Mamenchisaurinae.[1]
