Temporal range: Cambrian Series 3
|Species:||† S. hirpex|
Caron et al. 2010
Stanleycaris is an extinct, monotypic genus of anomalocaridid which existed in Canada, during the middle Cambrian (Cambrian Series 3). It was first named by Jean-Bernard Caron, Robert R. Gaines, M. Gabriela Mángano, Michael Streng and Allison C. Daley in 2010 and the type species is Stanleycaris hirpex. Stanleycaris described from the Stephen Formation near the Stanley Glacier Burgess Shale locality and also informally reported from Mount Odaray.
Its 1–3 cm-long appendages are the most commonly found component, and comprise 11 podomeres with a row of steeply-angled double-pointed spines on their upper surface, and five curved spiny blades protruding from the inner surface. Aside from the double-pointed spines, the appendages resemble those of Hurdia or Peytoia in their overall form. Peytoias are sometimes associated with the appendages; these have a square central opening. One specimen also appears to include an associated Hurdia-like carapace.
Its generic name means "Crab of Stanley Glacier"; hirpex, L. "large rake", reflects the rake-like nature of its spiny appendages.
