Skaracarida
Skara is a genus of maxillopod crustacean known from the Upper Cambrian Orsten deposit of Sweden and similarly aged deposits in China. It is the only genus in the order Skaracarida and family Skaraidae, and contains three species: The feeding system of "Skara" resembles those of copepods and "Derocheilocaris", and the three taxa are accordingly grouped together as the clade Copepodoida. "Skara" is likely to have scraped or brushed the substrate to release food.
