Hypothetical size comparison of <i><a href="https://en.wikipedia.org/wiki/Antarctosaurus" class="extiw" title="en:Antarctosaurus">Antarctosaurus wichmannianus</a></i>, a problematic Cretaceous sauropod from South America. Various remains were described to this species including skull and limb material. Later researchers have cast doubt on the assignment of all the remains to one individual or species and may even belong to different types of titanosaurs.
