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.

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.

The strangest-looking animals from Sirius Passet are Pambdelurion and Kerygmachela. They are generally regarded as anomalocarids because they have long, soft, segmented bodies with a pair of broad fin-like flaps on most segments and a pair of segmented appendages at the rear. The outer parts of the top surfaces of the flaps have grooved areas ...
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 ...
About a half billion years ago, an ancient sea covered what is now the northernmost stretches of Canada. Its seafloor was long thought to be a dead zone, devoid of the oxygen needed to support ...
