Cambroraster is an extinct monotypic genus of hurdiid radiodont, dating to the middle Cambrian, and represented by the single formally described species Cambroraster falcatus.[1] Hundreds of specimens were found in the Burgess Shale, and described in 2019.[2] A large animal (for its era) at up to Шаблон:Convert (but not as long as Titanokorys at Шаблон:Convert), it is characterized by a significantly enlarged horseshoe-shaped dorsal carapace (H-element), and presumably fed by sifting through the sediment with its well-developed tooth plates (oral cone) and short frontal appendages with hooked spines.[1] Nicknamed the "spaceship" fossil when first found, for the way its dorsal carapace resembles the fictional Millennium Falcon, the specific epithet falcatus in its scientific name is a nod to that resemblance.[1][3][4]

A second species of Cambroraster is known from the Chengjiang Biota of South China, making it the first uncontroversial hurdiid from the Cambrian of China. This species is known only from a juvenile dorsal carapace, so it was not given a specific name.[5]
Although originally suggested to have used its frontal appendages to sift sediment for prey, a later study by different authors suggested that it may have been a filter feeder instead.[6]
