Introduction

A well preserved naturally mummified human head has been found in 1936
 by Justiniano TORRES APARICIO, MD and folkmusic composer.
with two other mummies at the site of Inca Cueva #4, level 1A,
at 3680 m.o.s.l., in the Quebrada of Chulin (Prov.of Jujuy, Argentina)
A sample of temporal skin from the head of Chulina 
has been radiocarbon dated at the AMS Radiocarbon Laboratory
of the Federal Polytechnic Institute in Zürich.
The age of this paleoandean head is 5'260 ± 50 year BP, i.e., older than 
Ötzi
(the paleoalpine mummy found in Ötztal)by 724 ± 53 year BP.
 

The sample studied:

For this study, was available a piece of temporal
skin of  about 3 cm2 area and of a weight of 120 mg.

This sample was been carefully collected at the
 Museo J. TORRES APARICIO 
in Humahuaca (Prov. Jujuy, Argentina),
on the "Cabeza J.T.A.-240"

Let us remark that, the three mummies found by J. TORRES APARICIO
were  desiccated naturally, and therefore suitable to be radiocarbon dated.
(to the contrary, a radiocarbon dating of the embalmed 
Egyptians mummies would be meaningless).

The skin sample has then been thoroughly degreased and washed from contaminants.
Then, the standard ETH 14C-AMS dating method, which has been applied for
Ötzi
and results released on July, 8th, 2005 as ETH-30630.

The Results:
The δ13C = -19.5 ± 1.1 °/°° which is what one could expect for human skin.
The
14C-AMS Age is 5'260  ± 50 y BP
The calibrated age is BCE 4170 - 3972 with 82.5% probability
 (while the age range BCE 4224 - 4180 has 17.5% probability).
