The Segamai: Giant Ground Sloth?

I ran across some older (2001) material on possible giant ground sloth folklore. The Segamai is a Peruvian folkloric creature that has similarities to Brazilian Mapinguari folklore. A description and brief discussion of the Segamai can be found here (see ch. 16, pp. 172-3). David Oren's discussion of the possibility of surviving giant ground sloths can be found here.
