Came here to say this ⬆️. Well I do not dispute the potential for their existence (if not a mistake or typo) a 13 meter (42.65 ft) femur is a bit near-fetched, as George Carlin would say; 1.3 meters per the picture? Also the picture of the guy with the femur looking like it was just dug up does not look like 1930s or earlier vintage picture or clothing, in my view.
