The H. s. idaltu papers on free online at
The paper on the dating of the specimens (separate from the anatomy paper)
describes how they are dated using 40Ar/39Ar (NOT radiocarbon, which would
yield nothing of use at that age). The specimen itself isn't dated
directly; instead, as is the case for all older material, its age is
bracketed by datable igneous units above and below it. So: no, the funerary
practices would not in any way change the argon/argon ages.
