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 ...
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.
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]
[17] T. distos, though incomplete, is the longest with 3 cm body length and bears at least nine pairs of legs. [ 18 ] Hallucigenia species are highly diverse in body sizes, H. fortis is only about 1 cm long, H. hongmeia is intermediate with about 3 cm in length, and H. sparsa being the longest measuring 5.5 cm.

The discoverer, Charles Doolittle Walcott, described it as a kind of worm in 1911, but it was later identified as a chordate. [1] Subsequent discoveries of other Cambrian fossils from the Burgess Shale in 1991, [2] and from the Chengjiang biota of China in 1991, [3] which were later found to be of chordates, [4] [5] several Cambrian chordates ...
Wiwaxia fossils—mainly isolated scales, but sometimes complete, articulated fossils—are known from early Cambrian and middle Cambrian fossil deposits across the globe. [ 4 ] [ 6 ] [ 7 ] The living animal would have measured up to 5 centimetres (2 in) when fully grown, although a range of juvenile specimens are known, the smallest being 2 ...
