This method of reconstructing incomplete skeletons based on the more complete remains of related dinosaurs continues in museum mounts and life restorations to this day.

When compared to the same bone in related dinosaurs, this indicates that Agustinia may have been about 50 feet (15 meters) long.

These 'double beams' are also seen in some related dinosaurs.
