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.
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.
The Burgess Shale was the first of the Cambrian lagerstätten to be discovered (by Walcott in 1909), and the re-analysis of the Burgess Shale by Whittington and others in the 1970s was the basis of Gould's book Wonderful Life, which was largely responsible for non-scientists' awareness of the Cambrian explosion.

Estimated to reach 34.2–37.8 cm (13.5–14.9 in) long excluding the frontal appendages and tail fan, [4] Anomalocaris is one of the largest animals of the Cambrian, and thought to be one of the earliest examples of an apex predator, [5] [6] though others have been found in older Cambrian lagerstätten deposits.
Sam Tyler described Composite Creatures as "eerie, yet familiar", with "a strange unerring feel to it". [7] Writing in SF Book Reviews Tyler stated that the book's strength is Hardaker's "poetic world building", but hidden beneath the poetry and the everyday lives of Norah and Arthur is "shocking Science Fiction and Horror". [7]
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 ...
