Hurdiidae is a clade of anomalocaridan. It is the most long-lived anomalocaridan clade, lasting from the Cambrian period to the Devonian period.[1]

Definition

Hurdiidae is the most inclusive clade containing Hurdia victoria but not Amplectobelua symbrachiata, Anomalocaris canadensis, or Tamisiocaris borealis.[1]

Phylogeny

The most recent phylogeny of hurdiids, accompanying the description of the hurdiid Aegirocassis benmoulae, is as follows:[2]
