Species: Titanosauria indet.Oospecies: Megaloolithus sp.Age: Upper Cretaceous (Campanian-Maastrichtian)Formation: Allen Formation (?)Provenance: Patagonia, ArgentinaSize: ±30mm (1.1")Condition: No repair; has some staining on the back from old mineral tack; stabilized with Polyvinyl butyral (PVB) in acetone This is a listing for 1 titanosaur eggshell from Argentina. These eggshells are commonly referred to the genus Saltasaurus robustus or S. loricatus, however, this genus is no longer valid. There are many titanosaur genera from this region such as Bonatitan, Rocasaurus, and Aeolosaurus. While dinosaur fossils from South America are more or less impossible to obtain, "Saltasaurus" eggshells are one of the few exceptions. They were exported in mass quantities in the past, and while the supply has dried up considerably, they are still available to collectors. However, it isn't entirely known if they all come from the same place, commonly believed to be the Allen Formation. Pleas
