Is it marked "Made in Mexico"? :-) :-) Stone spheres, both man-
made and natural are quite common. Lots of people make stone
spheres. Also, this sphere also could be a natural spherical
concretion as illustrated in:

Hanson, W. D., and J. M. Howard, 2005, Spherical Boulders
in North-Central Arkansas. Arkansas geological Commision
Miscellaneous Publication no. 22, 16 pp.

and "Moeraki boulders" at [homepages.ezysurf.co.nz] and "Menzies'
Psuedo-Artifacts at [www.hallofmaat.com].

The questions, which need to be answered are 1. is this spherical
object natural or man-made? and 2. if man-made, who made it? I do
not understand how certain people on the GHMB have this blind and
misplaced faith in the assumption that if something is a large
stone sphere that it been made by Olmecs as if they had some sort
prehistoric patent or monopoly on the production of stone spheres.
