Caribemys anchors a conservative crown-turtle calibration
A published best-practice analysis used one Oxfordian holotype for a crown-Testudines hard minimum and kept the much older crown age as a probabilistic model result.
Represented range161.5–155.6 Ma
RegionsJagua Formation, Cuba; Bayesian relaxed-clock model
Caribemys holotype MNHNCu P-3209 supports a 155.6 Ma hard minimum for crown Testudines in the cited calibration scheme, whereas the older posterior crown interval is conditional on topology, molecular data, priors and clock model.
