For whatever reason fringe theorists and pseudoscientists have this belief that the megalithic sites in Peru and Bolivia used a rare plant that softens stone to mold them into place.It is said that there is a type of bird that lives deep in the Amazon basin that uses a plant to make its nests in stone. The plant supposedly has a chemical property that melts away or makes stone malleable.The stones at Sacsayhuaman look as if they were once clay molds and even show signs of vitrification on their outside layers.
There are however logical explanations that explain how the Inca and other groups in the area used round stones to shape these huge megaliths to where they look like the perfect fit. A rumored story of an Amazonian tribe who have a dislike for the bird supposedly called the “Montana”,states that it would annoy the tribes by waking them up early in the mornings.The tribe spotted the nest of hatchlings and tried to cover it up with stones in an effort to silence their loud cries.Later they had discovered a hole where the bird was able to seemingly melt the stone away either using the plant or its nearly indestructible beak to attend to its young.The bird supposedly has a super strong beak that is similar to the North American Woodpecker and is supposedly able to pile drive its way into stone to make a protective nest.
Could this bird have been able to chisel holes into stone could its beak be the tool used to cut and shape stones in the ancient world ? Most likely not so, but it is a very interesting theory that lacks any hard credible and factual evidence to support it.
There are many species of plants and animals that we as humans have not located on this planet, but a stone softening plant seems a little absurd.Another story involves mixing two plants together(one being the abundant cocoa leave) to get the stone softening juice.The idea seems impossible, but when there is little evidence to support how these stones were shaped, then we are left to come up with these unorthodox and seemingly impossible methods such as disaggregation,to explain the smooth signs of vitrification that are found in many sites in Peru.
