Is There a Llamas Fetus in Bolivia?

Llama fetuses are buried under the foundations of many Bolivia houses as a sacrifice to a pre-Columbian goddess. Tiwanaku was my favorite Pre-Columbian site after Matcha Picchu and Cusco. They think that it influenced the Inca civilization and the famous Wari civilizations. There's a temple, a subterranean temple with some amazing carved heads on the walls.
