The photo caption in this Smithsonian bulletin lists the marker as 1 foot. I believe it may in fact represent 27 cm – (5 bars of 5 cm, and 1 additional centimeter at the ends of the stick).
Comparing this scale marker to the size of the femur, it would suggest a femur approx. 24 – 26 inches long. The skeleton may have been of a man from 7 to 8 feet tall — assuming this marker is indeed at least 27 cm long.
This find was brought to my attention by Neo, of Ark and Neo: http://diggingforthetruth.podomatic.com/
They have been finding scores of amazing and interesting newspaper articles on giant skeleton finds, and other bizarre reports in the archives!
