<P> In 1939 , archaeologist Matthew Stirling discovered at Tres Zapotes the bottom half of Stela C . This stela was carved from basalt , with one side showing an Olmec - style engraving that has been variously characterized as an abstract were - jaguar or a ruler on a throne . On other side was the oldest Mesoamerican Long Count calendar date yet unearthed . This date , 7.16. 6.16. 18 , correlates in our present - day calendar to September 3 , 32 BCE , although there was some controversy over the missing baktun , the first digit , which Marion Stirling , Matthew 's wife , had contended was a ' 7 ' . Her judgment was validated in 1969 when the top half of the stela was found . </P>
