Arthropoda

The Arthropoda root display replaces the unsupported 540 Ma value with a 521–0 Ma sampled navigation envelope anchored by widespread trilobites, a contained arthropod clade, and living arthropods; it does not date the origin of Arthropoda. This navigation entry is not a phylogeny or a complete taxon dossier.
