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, [7] 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.
The type species is Houcaris saron which was originally described as a species of the related genus Anomalocaris. [1] Other possible species include H. magnabasis and H. consimilis . [ 2 ] [ 3 ] The genus Houcaris was established for the two species in 2021 and honors Hou Xianguang, who had discovered and named the type species Anomalocaris ...

Schinderhannes bartelsi is a species of hurdiid radiodont (anomalocaridid), known from one specimen from the Lower Devonian Hunsrück Slates.Its discovery was astonishing because the latest definitive radiodonts were known only from the Early Ordovician, [1] at least 66 million years earlier than this taxon.
