Pleurodira

The Pleurodira display route borrows the 155.6 Ma Caribemys-based hard minimum for crown Testudines as a conservative navigation boundary; that calibration is not a Pleurodira origin date, direct ancestor or audited global first appearance. This navigation entry is not a phylogeny or a complete taxon dossier.

The Pleurodira display route borrows the 155.6 Ma Caribemys-based hard minimum for crown Testudines as a conservative navigation boundary; that calibration is not a Pleurodira origin date, direct ancestor or audited global first appearance.

claim:taxon:pleurodira
fossil-range · low

The cited 155.6 Ma Caribemys minimum constrains crown Testudines rather than Pleurodira specifically, so the former Pleurodira range is withheld pending a node-specific fossil calibration.
