Could be shaped like that from a baby. Like they do feet and stuff. Who knows
could be
and it could be something else
Throughout history, many cultures have artificially deformed the skulls of babies in order to achieve a flattened or elongated shape which was often associated with the ruling, or elite classes.
Examples of artificial cranial deformation have been uncovered in Australia, the Middle East, Europe, Russia and the Americas in ancient times, as well as Oceanic and African tribes in modern times. When examined, most of these skulls exhibit features common to modern skulls, such as 3 cranial plates and sutures as well as a brain size of around 1200-1400 ccm.
On the other hand, some of the large elongated skulls unearthed from a cemetery in
Paracas, Peru , possess other anomalous anatomical features such only 2 cranial plates and sutures, as well as a brain capacity of over 1500 cm, which is larger than many skulls today.
These skulls, which are between 1500 and 3000 years old, have been described by some alternative researchers as evidence of extra-terrestrial aliens. While recent DNA results indicate they are entirely human, their genetic origin has yielded surprising results.
