It was discovered in 1986, pulled from the Acula River near La Mojarra, Veracruz, Mexico, not far from the Tres Zapotes archaeological site.

[2] The right side of the stone features a full-length portrait of a man in an elaborate headdress and costume, although the bottom half of the carving is very badly weathered.

A "Jester God" head with buccal mask sprouts from the bird-deity's nose, and a stylized shark with serrated fin is attached to the top of the headdress, its bifurcated tail hanging down behind.

Smaller bird deity masks appear below the main one and on the pectoral ornament that lies on the ruler's breast over his feather cape.

In November 1995, as the monument was being prepared for display, a previously neglected series of glyphs was noticed on one side in eroded but still partially recognizable condition.
