Primary redescription based on more than 1,800 Burgess Shale specimens, including figured mandibles and cephalothoracic appendages.
A series of more than 1,800 Waptia fieldensis specimens, including mandible-bearing ROMIP 56432 and disarticulated ROMIP 64294, documents a bivalved mandibulate body plan; pancrustacean placement and swimming-predator ecology remain topology and functional interpretations.
claim:event:waptia-mandibulate-seriesWaptia fieldensis is documented by a large specimen series and placed among mandibulates; exact pancrustacean position is an analytical result, not ancestry.
claim:taxon:waptia:taxonomyThe profile represents Burgess Shale material and does not infer Waptia’s complete distribution.
claim:taxon:waptia:biogeographySwimming and feeding modes are inferred from appendages and mandibles; prey, speed and habitual behaviour were not directly observed.
claim:taxon:waptia:ecologyMore than 1,800 specimens, including ROMIP 56432 and ROMIP 64294, document a bivalved carapace, mandibles and serial appendages.
claim:taxon:waptia:morphologyThe 508 Ma display point is a Burgess Shale sample context, not a global species duration or pancrustacean crown age.
claim:taxon:waptia:fossil-rangeThe Mandibulate evidence route navigation entity is source-linked only to the named specimen, dataset and analysis dossiers already cited by its range ledger. Its displayed span is a study-bounded route or sample envelope, not a biological taxon, ancestor sequence, global FAD/LAD or exact origin interval.
