The Cambrian explosion (also known as Cambrian radiation [1] or Cambrian diversification) is an interval of time beginning approximately in the Cambrian period of the early Paleozoic, when a sudden radiation of complex life occurred and practically all major animal phyla started appearing in the fossil record.
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 ...
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 ...
Lomankus is significant, as it represents the youngest known definitive megacheiran in the fossil record, as well as the only definitive member of the order from post-Cambrian strata. Although several other genera of post-Cambrian arthropods, including members of the family Enaliktidae , have been proposed as members of megacheira, their ...
A large hymenocarine arthropod that most likely lived a mainly nektonic lifestyle. This creature had about 110 pairs of biramous limbs, the most of any Cambrian aged arthropod. Loricicaris: Arthropoda: Order Hymenocarina. Collins Quarry; A hymenocarine with an elongated, spined abdomen. It was found in the Kicking Horse Shale Member of the ...
Pseudoarctolepis (meaning "false Arctolepis") is an extinct genus of bivalved arthropod known from the Cambrian period. The type species, P. sharpi was described by Brooks & Caster in 1956 from specimens found in the Wheeler Shale of Utah. [1]
The name Boeckelericambria honours W. Böckeler, alongside referring to the Cambrian age of the fossil. The species name pelturae refers to Peltura , the index trilobite of Zone 5 (where the fossil was found) [ 1 ]
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]
