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.

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 .

An important part of recognizing the structure as a nerve cord was fossilized nervous systems in other animals from the Cambrian Period (541 million to 485.4 million years ago) that were ...
[10] [2] A nearly complete specimen of a juvenile Lyrarapax unguispinus measured only 18 mm (0.71 in), making it among the smallest radiodont specimens known, though adults reached a length of 8.3 cm (3.3 in) [2] [13] An isolated frontal appendage of a hurdiid with a length less than half that of the juvenile Lyrarapax is known, but it is not ...
Every once in a while, evolution stumbles across a good idea and really runs with it. Despite its odd appearance, the Cambrian creature Odaraia alata—an arthropod whose taco-shaped carapace ...

[2] [3] It is famous for the exceptional preservation of the soft parts of its fossils. At old (middle Cambrian), [4] it is one of the earliest fossil beds containing soft-part imprints. The rock unit is a black shale and crops out at a number of localities near the town of Field in Yoho National Park and the Kicking Horse Pass.
