Omnidens, meaning "all-tooth", is an extinct genus of large Cambrian animal known only from a series of large mouth apparatus and sclerotized talon-like structures, originally mistaken as the mouthparts of anomalocaridids. [1] When first named, it was interpreted as a giant priapulid, [1] but is now considered a panarthropod. [2]
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 ...
The Miaolingian is the third Series of the Cambrian Period, and was formally named in 2018. [4] It lasted from about 506.5 to 497 million years ago and is divided in ascending order into 3 stages: the Wuliuan, Drumian, and Guzhangian. The Miaolingian is preceded by the unnamed Cambrian Series 2 and succeeded by the Furongian series. [5]

[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 ...
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.

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. This structure only covers the frontmost part of this arthropod but it does extend ventrally beyond its appendages. [1]
