This is a Mexican Mummy with an elongated skull. There are hundreds of mummies found in Mexico and displayed to the public. This mummy you can see an elongated skull, i am not sure whether it is hereditary by high neotony or if the skull was elongated artificially. This is an interesting specimen, the height and brain size is unknown.
This is the cave in Mexico in which the mummy was found. It would seem that this may have been an ideal position to defend oneself from very large predators.

Hard to say if neotony or artificial, but the artificial assertion has near global validation. Sites specimans are found in many places, such as Mexico, Peru, Egypt and USA to name a few. Most important question to ask is, why did they do it? Did it give them some advanced ability, such as ESP or increase the ability of their brains to perform logic or memory tasks? We need to find out exactly why these ancient people performed the same act of elongating their skulls. Further, could there have been ancient sea or land routes between these parties because of the proliferation of this knowledge over thousands of miles?
