3d model of the Pre-columbian artifact, made by me in blender. gallery listing for the original; https://collections.lacma.org/node/215157
Acording to the Los Angeles County Museum of Art the artifact is from the Calima Region in Colombia, and dates from between 1500 BCE and 100 CE. It is 5 1/2 × 6 × 5 in. (13.97 × 15.24 × 12.7 cm)
There are several other examples of crab shaped vessels from the pre-columbain period, they don't seem to be regional, with other examples I found online coming from all over South America. this was the only two spouted version I saw tho.
