A Lower Silurian ostracod with preserved soft parts provides a directly described specimen-level occurrence and anatomical assignment. One local specimen supplies only a minimum record; it does not establish the class's origin, global FAD or complete range. This navigation entry is not a phylogeny or a complete taxon dossier.

The 450–0 Ma Ostracoda display begins with the first unequivocal pre-Silurian ostracod occurrence and excludes less secure older shell-only assignments.

Known limits
A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
PBDB mapping requires concept review because the pinned lineage is incompatible with the local expected parent Crustacea.
