@mushroom soup It may be a real corpse that had weird skull and bone modification procedures done to it, that stuff is relatively common in the area. Last time the guy had another set of somewhat weird mummies that were that way. https://www.gaia.com/video/update-1-discovery?fullplayer=feature 

 @Zettour last time he did that it looked much more believable though (this is a Nazca child mummy that he ripped fingers and toes off and...covered in plaster?)

 @Zettour if the alien in op actually has a mummy in it then it's been severely altered,  mummies don't look like that
