A morphology-based character matrix tests relationships among sampled malacostracan orders. The resulting topology is an analytical hypothesis and neither dates Malacostraca nor samples every fossil lineage. This navigation entry is not a phylogeny or a complete taxon dossier.

The 500–0 Ma Malacostraca display uses the reviewed phyllocarid fossil minimum and must not be interpreted as a crown-Malacostraca divergence date.

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.
