The hindlimbs of Patagosaurus are based on scant material, some femora, a tibia and a few nondescript pedal bones. Two femora come from an adult, with a single additional bone known from the juvenile. The adult femora are proportionately different from the juvenile, being mostly straighter and more ovoid in cross-section.
