Genus: Skara
Müller, 1983

Skara is a genus of maxillopod crustacean known from the Upper Cambrian Orsten deposit of Sweden and similarly aged deposits in China.[2] It is the only genus in the order Skaracarida, and contains three species:[3]

  • Skara anulata Müller, 1983
  • Skara minuta Müller & Walossek, 1985
  • Skara huanensis Liu & Dong, 2007

The feeding system of Skara resembles those of copepods and Derocheilocaris, and the three taxa are accordingly grouped together as the clade Copepodoida.[4] Skara is likely to have scraped or brushed the substrate to release food.[5]
