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]
