{{italictitle}} [[File:Cambroraster.jpg|thumb|250px|''Cambroraster'']] '''''Cambroraster falcatus''''' is a [[stem group]] (ancestral) [[arthropod]]. Hundreds of specimens were found in the [[Burgess Shale]].<ref>{{cite news |last=Wu |first=Katherine J. |date=30 July 2019 |title=Meet ''Cambroraster falcatus'', the sediment-sifting 'Roomba' of the Cambrian |url=https://www.pbs.org/wgbh/nova/article/cambroraster-falcatus-cambrian |work=Nova |location= |access-date=31 July 2019 }}</ref> It was a large animal (for its day): it was up to 30{{nbsp}}cm long. It had a horseshoe-shaped [[carapace]], and probably fed by sifting through the [[sediment]] with its round mouth lined with hooked spines. This [[predator]] lived more than 500 million years ago. Its [[fossil]] has been discovered in [[Kootenay National Park ]] in the [[Canadian Rockies]]. ''Cambroraster falcatus'' is perhaps ancestral to [[insects]], [[crabs]] and [[spiders]]. The fossils were discovered by [[palaeontologists]] from the [[Royal Ontario Museum]] and [[University of Toronto]].<ref>{{cite web | url=https://www.sciencedaily.com/releases/2019/07/190731155943.htm | title=A voracious Cambrian predator, Cambroraster, is a new species from the Burgess Shale }}</ref> == Related pages == *[[Cambrian explosion]] ==References== {{reflist}} [[Category:Fossils]] [[Category:Cambrian]]
