Opabinia regalis is an extinct, stem group arthropod found in the Middle Cambrian Burgess Shale Lagerstätte (505 million years ago) of British Columbia. [1] Opabinia was a soft-bodied animal, measuring up to 7 cm in body length, and had a segmented trunk with flaps along its sides and a fan-shaped tail.
Estimated to reach 34.2–37.8 cm (13.5–14.9 in) long excluding the frontal appendages and tail fan, [4] Anomalocaris is one of the largest animals of the Cambrian, and thought to be one of the earliest examples of an apex predator, [5] [6] though others have been found in older Cambrian lagerstätten deposits.
Omnidens, meaning "all-tooth", is an extinct genus of large Cambrian animal known only from a series of large mouth apparatus and sclerotized talon-like structures, originally mistaken as the mouthparts of anomalocaridids. [1] When first named, it was interpreted as a giant priapulid, [1] but is now considered a panarthropod. [2]
Every once in a while, evolution stumbles across a good idea and really runs with it. Despite its odd appearance, the Cambrian creature Odaraia alata—an arthropod whose taco-shaped carapace ...
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 close relative of Hurdia that was originally named as a jellyfish, but was later recognized as the oral cone of the creature. This creature is also known from European deposits. Stanleycaris: Stem-group Arthropoda. Radiodonta: Stanley Glacier; A basal hurdiid radiodont known from a variety of Cambrian deposits in North America.
This list contains many extinct arthropod genera from the Cambrian Period of the Paleozoic Era. Some trilobites, bradoriids and phosphatocopines may not be included due to the lack of literature on these clades and inaccessibility of many papers describing their genera. This list also provides references for any Wikipedia users who intend to ...
Hallucigenia is a genus of lobopodian known from Cambrian aged fossils in Burgess Shale-type deposits in Canada and China, and from isolated spines around the world. [4] The generic name reflects the type species' unusual appearance and eccentric history of study; when it was erected as a genus, H. sparsa was reconstructed as an enigmatic animal upside down and back to front.
