Isn't it interesting -- and so very, very sad -- that the denizens 
of the sci news groups -- particularly talk.origins, sci.anthropology,
sci.anthropology.paleo. sci.paleontology.mesoamerican

moderated groups -- are totally convinced the specimens
shown in the URLs below are nothing but rocks and/or
concretions.

Because those objects looked like rocks, not like bones or anything else.
