A mitogenomic sample of living chimaeriforms; model ages do not date total-group Holocephali directly.
Mitogenomes representing all three living chimaeriform families provide a sampled topology and molecular divergence estimates. The living sample and clock model do not directly date total-group Holocephali or establish its fossil endpoints.
claim:taxon:holocephaliA calibrated mitogenomic analysis estimated the shark–ray split near 281 Ma, supporting a model-dependent 281 Ma–present window for modern elasmobranch lineages, not a total-group fossil FAD.
claim:taxon:elasmobranchii:range-boundaryThe mitogenomic clock estimated the lineage leading to modern holocephalans at 421 Ma (95% credible interval 410–447 Ma), supporting a model-to-present window rather than a fossil FAD.
