About 27 femora are known from Bellevue, making them the most common bone, most of them more-or-less complete. They are very flat craniocaudally but otherwise, lack any unusual features. In a study of its bone physiology, it was found that the maximum known femur length was , which is much larger than previously known (). That means, that the ancestors "Ampelosaurus" were slightly smaller than itself. 18 humeri are also known, but none of them approach the size of the largest femur. The humeri do not have a free medullary cavity. The humeri are robust, about long, with very expanded distal and proximal ends.
