Tuzoia.

Tuzoia is an extinct genus of large bivalved arthropod known from Early to Middle Cambrian marine environments from what is now North America, Australia, China, Europe and Siberia. The large, domed carapace reached lengths of 180 millimetres , making them amongst the largest known Cambrian arthropods.Tokummia has a cylindrical body, with the anterior half covered by a 8.78 cm (3.46 in) long bivalved carapace. At the front of the animal, there are a pair of antennae, possible eyes, mouthparts ( mandibles, maxillule and maxilla) and prominent pincer-like maxillipeds. These shows the oldest record of arthropod pincers.D. anima, as well as the newly reported Tuzoia. sp. from the Fandian biota, represent the oldest occurrence of Tuzoiidae, extending its stratigraphic range to Cambrian Stage 3 and expanding the palaeogeographical distribution of the group to the northern border of the Yangtze Platform.A fragment of a Burgess Shale-type fossil, bivalved arthropod Tuzoia Walcott, 1912, is described from shales of the mid-Cambrian Buchava Formation in the Skryje-Týřovice Basin, Central Bohemia, Czech Republic. It is the second recorded find of Tuzoia from West Gondwana.
