Caudal Pneumaticity and Pneumatic Hiatuses in the Sauropod Dinosaurs Giraffatitan and Apatosaurus

Figure 10

An isolated pneumatic fossa is present on the right side of caudal vertebra 13 in Apatosaurus excelsus holotype YPM 1980.

The front of the vertebra and the fossa are reconstructed, but enough of the original fossil is visible to show that the feature is genuine.
