However, radiometric dates obtained for volcanic minerals at Sangiran indicate that some Javan fossils may be substantially older, perhaps approaching 1,500,000 years in age.
Many sites have been excavated, with dates obtained for at least every 500 years since ∼5,000 bp.
If we are willing to accept that the youngest of each pair of dates obtained for individual RPCBs indicates the approximate timing of the HEMI events that produced the boulders, then it is helpful to plot the data on a timeline in order to visualise the relative frequency and magnitude of the events (Figure 4).
Given that no secure evidence exists elsewhere for peninsular Neandertals to have persisted beyond the 37th millennium cal BP, and that available archeological proxies place the emergence of anatomical modernity across southwest Iberia no later than the beginning of the 36th, the younger dates obtained for the Middle Paleolithic of Gorham's Cave must be considered anomalous [50].
The dating obtained for other nodes also seems to be mostly compatible with current knowledge.
However, this and the recent dating obtained for the basal splitting in the species tree might be underestimates caused by the anomalously low genetic substitution rates of fissiparous organisms misleading the methodologies used in the dating analyses.
The ancient dates obtained for the origin of each of the three armadillo subfamilies are coherent with their distinctive morphologies [ 69] and marked differences observed in the structure of their spermatozoa [ 70].
Although a phylogenetic tree alone does not allow drawing conclusions about the number of mtDNA lineages incorporated into the domestic gene pool, the molecular dates obtained for the divergence events in combination with knowledge about the timing of horse domestication allow some speculations on this issue.
This is the most accurate date obtained so far for the extinction, and it coincides with the start of a very cold period in Europe.
For the optical transmission T of SnO2 F (d = 200 nm) and CdS (d = 50 nm) the date obtained in "Accounting for absorption losses" can be used, i.e. the T transmission is given by Eq. (6).
