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 ...
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.
Prehistoric arthropods of the Cambrian period, during the Paleozoic Era. Subcategories. This category has the following 7 subcategories, out of 7 total. ...
Marrellomorpha are an extinct group of arthropods known from the Cambrian to the Early Devonian. [1] They lacked mineralised hard parts, so are only known from areas of exceptional preservation, limiting their fossil distribution. The best known member is Marrella, with thousands of specimens found in the Cambrian aged Burgess Shale of Canada ...
Odaraia is a genus of bivalved arthropod from the Middle Cambrian. Its fossils, which reach 15 centimetres (5.9 in) in length, [1] have been found in the Burgess Shale in British Columbia, Canada. Odaraia bore a large pair of eyes at the front of its body, [1] and may have had two smaller eyes in between. [2]
Balhuticaris was the largest bivalved arthropod in the fossil record, beating the previous holders of this title Nereocaris exilis and Tuzoia. This animal's body was very long, and had extreme segmentation compared to other Cambrian arthropods, with over 100 distinct segments.
Parapeytoia is a genus of Cambrian arthropod. The type and only described species is Parapeytoia yunnanensis, lived over 518 million years ago [2] (Cambrian Stage 3) in the Maotianshan shales of Yunnan, China. Unidentified fossils from the same genus also had been discovered from the nearby Wulongqing Formation (Cambrian Stage 4). [3]
Bradoriida are geographically widespread, and first occur in the fossil record shortly before the earliest trilobite fossils. [1] Their taxonomic composition broadly reflects two geographical provinces ("European" and "4A", i.e. America, Asia, Australia, Antarctica) which approximately mirror trilobite provinces, with the 4A area representing ...
