He fully agrees with absolute dating methods for clay tablets or coins like thermoluminescence dating, optically stimulated luminescence dating, archaeomagnetic, metallographic dating, but claims that their precision does not allow for comprehensive pinpointing on the time axis either.
Since the early years of the twentieth century, absolute dating methods, such as radiometric dating ( including uranium series, and, for very recent fossils, radiocarbon dating ) have been used to verify the relative ages obtained by fossils and to provide absolute ages for many fossils.

Accordingly, the debate about temporal priority will remain unresolved unless and until other absolute dating methods such as archaeomagnetics and luminescence ( hitherto, thermoluminescence ), are applied more widely, or Long Count-dated texts, e . g ., Cycle 6, are found earlier than those found thus far, which are Cycle 7.
The temporal priority of plentiful as opposed to scant evidence of stelae and writing in the Preclassic south compared to the Mirador Basin must be based principally on absolute dating, although this problem, itself, becomes difficult to resolve when events are dated by 14 C ( calibrated or uncalibrated ) still the most widely used absolute dating method in Mesoamerica and which cannot be rendered more fine-grained than ca . 100 years and often is less precise.
