Summary
Orange-on-white pottery from Etlatongo.

In an effort to address questions concerning the geographic origin of Olmec-style artifacts — with implications concerning the geographic origins of Olmec culture — in March 2005 a team of archaeologists used INAA (instrumental neutron activation analysis) to compare over 1000 ancient Mesoamerican Olmec-style ceramic artifacts with 275 samples of clay so as to "fingerprint" the origin of that pottery.
