This is an amazing discovery, but of course others have been found as well. However, to my knowledge they were very small or not as obviously alien. I asked my inner-planes mentor, ThothHorRa about this particular one (and apparently others found in the same region of Peru). I received that they were of the more friendly variety…not the scientist that abduct people in the night. They did create some hybrids, but this was through natural assimilation with the people of the region.
