I asked Mr. Juan Carlos
I asked Mr. Juan Carlos Arroyo Navarro (grandson of Mr. Juan Navarro Hierro and current owner of the Paracas History Museum) to show me what could be the largest skull in the museum's collection. And I asked him to help me measure its cranial capacity (where the brain fits inside).
I found our that the volume in cubic centimeters was within the normal range. I also measured the cranial capacity of another of the larger skull whose sagittal suture was basically unnoticeable (this is a normal occurrence in some persons, sometimes with age). The results were basically the same, or within the normal range. Both skulls had about 1300 cc using a direct method.
The largest skull also had an interior cranial capacity within the normal range using a direct method, but a larger measurement (although still within human limits) using an indirect craniometric method of taking linear measurements of length, width, height.
Pseudo anomalies have been mentioned by some researchers who think that the parietal fossa (holes) are unique of the Paracas people and their elongated skulls but that is not correct. Normal skulls have them as well. This makes me doubt about other such claims.
To conclude, in relation to my initial research pertaining to brain volume, I don't deny the possibility of genuine anomalies or unique characteristics but, to say that the Paracas skulls are those of physical giants based on appearance and internal volume/brain capacity would be not correct.
Other characteristics perhaps found in the Paracas skulls, such as the alleged initial findings of genetic haplo groups that otherwise occur in the area of the Black Sea and Crimea in Europe might be correct but need to be studied by more scientific teams. Also, shape and position of the foramen magnus as seen insome Paracas skulls might be "anomalous" (in the sense of being part to a different sub-species of human) or it may simply be an adaptation to the shape and weight distributions resulting from artificial elongation.
