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 ...
Prehistoric arthropods of the Cambrian period, during the Paleozoic Era. Subcategories. This category has the following 7 subcategories, out of 7 total. ...
The Cambrian (/ ˈ k æ m b r i. ə n, ˈ k eɪ m-/ KAM-bree-ən, KAYM-) is the first geological period of the Paleozoic Era, and the Phanerozoic Eon. [5] The Cambrian lasted 51.95 million years from the end of the preceding Ediacaran period 538.8 Ma (million years ago) to the beginning of the Ordovician Period 486.85 Ma.
Isoxyids are members of the order Isoxyida and the family Isoxyidae, a group of basal arthropods that existed during the Cambrian period. It contains two genera, Isoxys, with 20 species found worldwide, and Surusicaris known from a single species found in the Burgess Shale of Canada. They are distinguished by their bivalved carapaces and pair ...
Radiodonta is an extinct order of stem-group arthropods that was successful worldwide during the Cambrian period. Radiodonts are distinguished by their distinctive frontal appendages, which are morphologically diverse and were used for a variety of functions.
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 ...
The Fortunian stage and presently unnamed Cambrian Stage 2 are the stages within this series. The Terreneuvian corresponds to the pre-trilobitic Cambrian. [5] The name Terreneuvian is derived from Terre Neuve, the French name for the island of Newfoundland, Canada, where many rocks of this age are found, including the type section. [2] [4]
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 ...
