This article presents revised radiocarbon dates of the human bones from this site obtained using a more robust purification method targeting the amino acid hydroxyproline.
The data show that all the Neanderthal remains are from a much earlier period (Previous dating of the Vi-207 and Vi-208 Neanderthal remains from Vindija Cave (Croatia) led to the suggestion that Neanderthals survived there as recently as 28,000–29,000 B. Subsequent dating yielded older dates, interpreted as ages of at least ∼32,500 B. We have redated these same specimens using an approach based on the extraction of the amino acid hydroxyproline, using preparative high-performance liquid chromatography (Prep-HPLC).
Karavanić and Smith (19) have suggested that the mixture of elements may represent the interaction and possible acculturation between modern humans and late Neanderthals.

Stegodons are thus important for understanding some key biological phenomena including the dispersal abilities of large-bodied mammals and the evolutionary mechanisms of island dwarfing.
Primary pitchblende mineralization from the Collins Bay unconformity-type uranium deposit in northern Saskatchewan has been dated using the Sm-Nd method.
The European record for the transition retains its interest because it is the best-documented sequence for the disappearance of a hominin group available (3). Ascertaining the spatial attributes of Neanderthal and modern human populations in Europe is an area of active research, and a reliable chronology remains essential. (Vi-208: Ox A-X-2089-06), which indicated the previous dates were indeed too young.
