Lapedo remains affected by lightning strikes; redating by bootstrap
The remains of what is dubbed the Lapedo Child were originally estimated, based on stratigraphy and associated artifacts in upper sediments, to date from some time between ~40,000 and ~23,000, as Solutrean tools were found in layers above the burial, and the lower deposits were correlated to the late middle Paleolithic-upper paleolithic transition/OIS 3. Redating of the remains using hydroxyproline was published, from which I produced a model-based correction that may adjust for multiple scavenging-superposition effects within radiocarbon correction curves, which are never local in nature. My model is tabulated in this post, and the paper from which the left column dates were published is here in .pdf form: Linscott et al. 2025 https://pmc.ncbi.nlm.nih.gov/articles/PMC11887806/pdf/sciadv.adp5769.pdf Ochre staining covering the skeletal remains is consistent with effects on oxides from lightning strikes affecting the remains, reducing the oxidation state of particles of...
