Paleoekolohiya

An mga specimens kan Anomalocaris nanompongan sa bilog na kinaban spanning from Cambrian Stage 3 pasiring sa Guzhangian. Apwera sa Burgess Shale asin Emu Bay Shale, nanompongan an mga fossils sa Chengjiang Biota, Hongjingshao Formation, Balang Formation asin sa Kaili Formation kan Tsina, siring man sa Eagar Formation asin Weeks Formation sa Estados Unidos.[3]

An Anomalocaris canadensis namuhay sa Burgess Shale sa relatibong dakulang bilang.[1] In the Burgess Shale, an Anomalocaris komun sa mga daan nang sections, notable sa Mount Stephen trilobite beds. Minsan siring, in the younger sections, siring kan Phyllopod bed, posibleng nag-abot an Anomalocaris sa dakulang sukol; haros duwang beses kan saiyang mas gurang nang, trilobite bed relatives. An mga pambihirang tandayag na specimens dati nang pinanongdan na suhay na espesye. An Anomalocaris gigantea; minsan siring, an balidad kan mga species na ini pinag-apod tanganing kwestyunon,[4] and is currently synonymized to A. canadensis.
