Tigre Capiangos (Argentine)
The werejaguar (Tigre Capiangos) appears widely in the Olmec archaeological record, and in many cases, the werejaguar motif represents the werejaguar supernatural. The werejaguar supernatural incorporates the werejaguar motif as well as other features, although various academics define the werejaguar supernatural differently.
Originally, many scholars believed that the werejaguar was tied to a myth concerning a mating between a jaguar and a woman. Although this hypothesis is still recognized as viable by many researchers, other explanations for the werejaguar motif have since been put forward, several questioning whether the motif actually represents a jaguar at all.
