Most of the ones I have read about were in the 8 to 10 feet range in the US , I do remember reading an article about a discovery in Australia where the skeleton measured over seventeen feet.
Makes a person ask or question evolution, where were the 10 to 17 foot apes living that we evolved from?
None of it adds up and like you said, for every story there always seems to be a counter story in order to keep people spinning in circles when trying to figure things out.
