Amplectobelua was an anomalocaridid from the early to middle Cambrian.
The Chengjiang specimens of Amplectobelua were first described as “anomalocaridid animal 2” in Chen et al. (1994) and given a formal designation as Amplectobelua symbrachiata by Hou et al. (1995). The Burgess Shale genus Amplectobelua stephenensis was described by Daley and Budd (2010) from six specimens of isolated appendages in the Royal Ontario Museum collections.
