This animal's body was very long, and had extreme segmentation compared to other Cambrian arthropods, with over 100 distinct segments. In total this creature had about 110 pairs of biramous limbs, the most of any Cambrian-aged arthropod. Covering the head of this creature was a large carapace that resembles an arch or other curved structure ...
A fossil of this creature and its tracks were discovered in 2019 in Southern China. [1] It was a segmented bilaterian , conceivably related to panarthropods or annelids . It is a rare example of a complex Ediacaran animal that is similar to animals that existed since the Cambrian , hence suggesting that perhaps the Cambrian explosion was less ...
Ottoia is a stem-group archaeopriapulid worm known from Cambrian fossils. [3] Although priapulid-like worms from various Cambrian deposits are often referred to Ottoia on spurious grounds, the only clear Ottoia macrofossils come from the Burgess Shale of British Columbia , which was deposited 508 million years ago .

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 ...

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.
