The largest known Cambrian radiodont was Amplectobelua, reaching lengths of up to 90 cm (35 in) based on an incomplete specimen. [15] Anomalocaris canadensis was also relatively large, estimated up to 34.2–37.8 cm (13.5–14.9 in) long, [2] and the Cambrian hurdiid Titanokorys approached around 50 cm (20 in) long. [16]
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 ...
Spectacularly preserved trilobite fossils, often showing soft body parts (legs, gills, antennae, etc.) have been found in British Columbia, Canada (the Cambrian Burgess Shale and similar localities); New York, U.S.A. (Ordovician Walcott–Rust quarry, near Russia, and Beecher's Trilobite Bed, near Rome); China (Lower Cambrian Maotianshan Shales ...
One example is a fossil specimen of the Cambrian arthropod Mollisonia, which showed brain organization comparable with that of living spiders, scorpions and horseshoe crabs, Mussini said.
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 ...
These new fossils give a clearer picture that O. alata contributed to an evolutionary arms race as its mandibles allowed the animal to break down large structures into smaller pieces and gain ...

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.
