HistoryUpper Paleolithic (~24,500 years ago)Lagar Velho, Portugalhigh confidence

The Lagar Velho child's grave was dug into a little-used section of a rock shelter, where pine branches were burned inside the pit before the body was placed there.

Notes on verification

Core claim of a fire lit in the burial pit before the body was placed is well-supported by peer-reviewed research and excavator accounts. The 'little-used section' detail is consistent with descriptions of a recess in the back wall, though exact phrasing is unique to Britannica.
