(Curry, Rogers & Forster, 2001) is a Late Cretaceous titanosaur sauropod that is known from several bits and pieces from 3 adults, plus the majority of a juvenile specimen (Fig. 1). Adult lengths are estimated up to 15 m.
In the large reptile tree (LRT, 1293 taxa) Rapetosaurus nests with the much taller and longer Diplodocus. Rapetosaurus has a much larger pubis for no better reason than to help support its guts when bipedal.
The down-turned snouts here
reflect their angle relative to the occiput and probably the semi-circular canals.
