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.
Omnidens is found in both the Chengjiang Biota and the Xiaoshiba Lagerstätte of China, putting their age at approximately 520 Ma, during Cambrian Stage 3. [7] O. amplus and O. qiongqii are both known from the Chengjiang, but O. qiongqii is the only Omnidens species present at Xioashiba, where it is found in relative abundance (hundreds of ...
Facivermis was a worm-like creature up to 90 mm long. Its body was divided into three sections. The anterior section had five equally sized pairs of appendages with two setal rows along the margins. The middle section was elongate and five times longer than the anterior or posterior.
An extinct ribbonlike sea creature about the size of a human thumb was one of the earliest animals to evolve a precursor of a backbone. Scientists recently identified the animal’s nerve cord by ...

A close relative of Hurdia that was originally named as a jellyfish, but was later recognized as the oral cone of the creature. This creature is also known from European deposits. Stanleycaris: Stem-group Arthropoda. Radiodonta: Stanley Glacier; A basal hurdiid radiodont known from a variety of Cambrian deposits in North America.
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.

Anomalocarididae [1] (occasionally mis-spelt Anomalocaridae [2]) is an extinct family of Cambrian radiodonts, a group of stem-group arthropods. [3] [4]Around 1990s and early 2010s, Anomalocarididae included all radiodont species, hence the previous equivalent of the common name "anomalocaridid" to the whole Radiodonta. [5]
