An epipodite-bearing crown-group crustacean from the Lower Cambrian

Phosphatized Yicaris dianensis individuals from several growth stages preserve leaf-shaped exites and eucrustacean-like limb organization; crown-eucrustacean placement and epipodite homology are character interpretations rather than an observed crown origin date.

Yicaris dianensis was interpreted near crown Eucrustacea from sampled appendage characters; that placement is not direct ancestry or a crown-origin date.

The profile is limited to the Chiungchussu Formation sample in Yunnan and does not establish a global range.

The developmental material does not directly preserve diet, habitat preference or locomotor performance.

Phosphatized individuals from multiple growth stages preserve leaf-shaped exites and eucrustacean-like limb organization.

The 521–514 Ma interval is a broad formation context for the developmental sample, not a global species duration or eucrustacean FAD.

The Crustacea root display uses a rounded 520–0 Ma sampled envelope from Lower Cambrian Yicaris material to living crustaceans; Yicaris crown-eucrustacean placement is a character interpretation and the number is not a crustacean origin date.

The Pancrustacea 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.
