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 ...

Geologic map of Sirius Passet with the Buen Formation shown in black. The oldest Cambrian series of the area was deposited in the Franklinian Basin and is poorly exposed in fragmentary, heavily metamorphosed outcrops in Peary Land. It was emplaced during the Ellesmerian orogeny. [2] [3]
Sirius Passet is a Cambrian Lagerstätte in Peary Land, Greenland.The Sirius Passet Lagerstätte was named after the Sirius sledge patrol that operates in North Greenland. It comprises six places in Nansen Land, on the east shore of J.P. Koch Fjord in the far north of Greenland. [1]
Originally described as crustacean arthropods, the Vetulicola were later erected as a new phylum of primitive deuterostomes by D.G. Shu. [5] In recent years, a majority of workers have come to see the vetulicolians as stem chordates, [23] and a 2024 study placed vetulicolians as a basal chordate evolutionary grade, followed by Yunnanozoon.

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.
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 ...
A nektaspid arthropod that belonged to the family Naraoiidae, that lived from the early Cambrian to the late Silurian period. The species are characterized by a large alimentary system and sideways oriented antennas. It reached small to average sizes (about 2-4.5 cm long). Hanburia: Arthropoda (unranked) Artiopoda.
