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.
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 ...
In 1979, Derek Briggs recognized that the fossils of Anomalocaris were appendages, not abdomens, but interpreted them as walking legs alongside "Appendage F". [88] It was not until 1985 that the true nature of the fossils of Anomalocaris, Laggania, and Peytoia was recognized, and they were all assigned to a single genus, Anomalocaris. [33]
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]
