Marrella is an extinct genus of marrellomorph arthropod known from the Middle Cambrian of North America and Asia. It is the most common animal represented in the Burgess Shale of British Columbia, Canada, with tens of thousands of specimens collected. Much rarer remains are also known from deposits in China.
Omnidens is found in both the Chengjiang Biota and the Xiaoshiba Lagerstätte of China, putting their age at approximately 520 Ma, during Cambrian Stage 3. [7] O. amplus and O. qiongqii are both known from the Chengjiang, but O. qiongqii is the only Omnidens species present at Xioashiba, where it is found in relative abundance (hundreds of ...

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.
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.

Ottoia is a stem-group archaeopriapulid worm known from Cambrian fossils. [3] Although priapulid-like worms from various Cambrian deposits are often referred to Ottoia on spurious grounds, the only clear Ottoia macrofossils come from the Burgess Shale of British Columbia , which was deposited 508 million years ago .

This animal's body was very long, and had extreme segmentation compared to other Cambrian arthropods, with over 100 distinct segments. In total this creature had about 110 pairs of biramous limbs, the most of any Cambrian-aged arthropod. Covering the head of this creature was a large carapace that resembles an arch or other curved structure ...
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 ...
