Bioapatite dating of the Neoesclerocalyptus bones, conducted in France, determined the skeleton to be 21,000 years old, marking the first such bone dating performed on this genus.
Notes on verification
Core dating details (French lab CIRAM, bioapatite AMS method, ~21,000 year result) directly confirmed by peer-reviewed PLOS ONE paper and multiple independent science media outlets. The 'first such dating for this genus' claim traces to a direct quote from a co-author, repeated across many outlets but not independently verified against the broader literature; no contradicting evidence found.
