I wasn't sure of that myself ... I pulled out my copy of Mexico by Michael Coe and Rex Koontz and found this information...I don't know if Tlatilco was an Olmec site or not ... but the time period is right I think ...

Quote

In the Tlatilco refuse are the bones of deer and waterfowl, while represented in the potter's art are armadillo, opossum, wild turkey, bears, frogs, rabbits, fish, ducks and turtles.

Quote

A distinctly macabre streak appears in the art of the inhabitants of Tlatilco, possessed by a psychological bent that delighted in monstrosities. To illustrate this point, one might mention such representations as two headed persons, or heads with three eyes, two noses, and two mouths; hunchbacks; idiots; horribly ugly and sometimes masked individuals who may be shamans; and many other outrageous deformities.
[...]
Forms include bowls, neckless jars, long -necked bottles, little spouted trays (possibly for libations), bowls and jars with three tall feet, and, most peculiarly, jars with spouts that resemble stirrups.

page 49-50

Just a bit further on stirrup pots are mentioned again ... at Chupicuaro some were found and Coe/Koontz say its the last time frame where stirrup jars are found.

There are a couple of pictures in Mexico of stirrup jars and once again they are all more decorated than this piece.
