Cryptodira

The Cryptodira route represents the sampled crown-side turtle clade in Joyce’s morphology matrix; relationships within Cryptodira are partly unresolved, and the analysis does not supply an exact crown origin or global first appearance. This navigation entry is not a phylogeny or a complete taxon dossier.
