[The story of Anomalocaris is] a tale of humor, error, struggle, frustration, and more error, culminating in an extraordinary resolution that brought together bits and pieces of three "phyla" in a single reconstructed creature, the largest and fiercest of Cambrian organisms. [11] Anomalocaris fossils were first collected in 1886 [8] by Richard ...
The largest known Cambrian radiodont was Amplectobelua, reaching lengths of up to 90 cm (35 in) based on an incomplete specimen. [15] 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]
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]
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 ...
This is a list of the biota of the Burgess Shale, a Cambrian lagerstätte located in Yoho National Park in Canada. Restoration of the nektonic environment of the site, showing a pair of Anomalocaris canadensis hunting a school of Isoxys acutangulus. The Burgess Shale is a fossil-bearing deposit exposed in the Canadian Rockies of British ...
Laminacaris size diagram. The large frontal appendage is the most prominent and distinctive feature in Cambrian arthropods. [3] [4] The largest frontal appendage of Laminacaris (YKLP 13338) is around 28 cm (11 in) long, which would have belonged to an individual between 53.2–78.4 cm (20.9–30.9 in) long, based on proportion of Innovatiocaris (which is once treated as "Anomalocaris" saron).

Burgessomedusa adds to the complexity of Cambrian foodwebs, and like Anomalocaris which lived in the same environment, these jellyfish were efficient swimming predators,” said study coauthor Dr ...
Lenisicaris is only known from frontal appendages, though these specimens have several distinguishing traits, most noticeably the lack of auxiliary spines. [5] The type species L. lupata has smaller, triangular endites, closely resembling those of Anomalocaris. [1]
