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.
Anomalocaris was a mainly soft-bodied swimming predator which was gigantic for its time (up to 70 cm = 2¼ feet long; some later species were 3 times as long); the soft, segmented body had a pair of broad fin-like flaps along each side, except that the last 3 segments had a pair of fans arranged in a V shape.
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]

Incredibly well-preserved fossils of the oldest swimming jellyfish, which lived 505 million years ago, were discovered at a famed fossil site in Canada.
H. saron, known from Maotianshan Shale in Yunnan, is first described in 1995 as Anomalocaris saron. [4] This species is only known from frontal appendages. There is a specimen (ELRC 20001) that is previously considered as whole body fossil of this species, [4] but later study shows that this specimen is not belonging to this species, and later given own genus Innovatiocaris.
