...help you put the osteoderm discovery into the environmental context that helps support our hypothesis about mineral storage (a camel's hump isn't quite the right analogy, since what we found is a big bone that is very similar to the osteoderms of living crocodilians --- except ours hollowed out over the course of the animal's lifetime). In the Sci Am paper Ray and Dave reconstruct a drought-prone nasty place to live (that resulted in the carnivorous Majungasaurus resorting to cannibalizing the carcasses of it's own species).
It's also kinda cool that Rapetosaurus is the first titanosaur to really be found with osteoderms associated that give us a clue as to how many and where they may have been positioned on the body - there weren't as many as shown in any of the posted illustrations, and the few that were there were relatively large.
I've attached a couple images that might help you! The first is a mounted skeleton of Rapetosaurus from the Field Museum of Natural History (Chicago) - the specimen is a small juvenile, like most of the animals that we've recovered from Madagascar.
The second is a shot from more recent field work - that's me standing next to an extraordinarily long cervical rib from an adult Rapetosaurus.
These are the photos mentioned:
