In radiocarbon terms, 31,892 BCE lies about 33,842 years before AD 1950, the conventional ‘present’ used in radiocarbon dating. That calculation is only a guide. Radiocarbon years are not calendar years: atmospheric carbon levels changed through time, and dates must be calibrated against independently dated records. At this depth in time, calibrated results are broad rather than annual.
