Anomalocaris ("unlike other shrimp", or "abnormal shrimp") is an extinct genus of radiodont, an order of early-diverging stem-group marine arthropods.. It is best known from the type species A. canadensis, found in the Stephen Formation (particularly the Burgess Shale) of British Columbia, Canada.
Anomalocarididae [1] (occasionally mis-spelt Anomalocaridae [2]) is an extinct family of Cambrian radiodonts, a group of stem-group arthropods. [3] [4]Around 1990s and early 2010s, Anomalocarididae included all radiodont species, hence the previous equivalent of the common name "anomalocaridid" to the whole Radiodonta. [5]
Anomalocaris canadensis was also relatively large, estimated up to 34.2–37.8 cm (13.5–14.9 in) long, [2] and the Cambrian hurdiid Titanokorys approached around 50 cm (20 in) long. [16] The body of a radiodont could be divided into two regions: head and trunk.
A new analysis of the extinct marine animal Anomalocaris canadensis suggests the Cambrian hunter was more of a weakling than once assumed. Ancient shrimplike predator was misunderstood, according ...

Peytoia nathorsti was subsequently considered a junior synonym of Anomalocaris canadensis, while Laggania cambria became recognized as a distinct genus and species again, [12] but in 2012 it was determined that Anomalocaris canadensis had an oral cone with only three large plates, unlike that of Laggania cambria and Peytoia nathorsti with four ...
