Tuzoia. Tuzoia (from Mount Tuzo, a mountain in the Canadian Rockies) 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 (7.1 in), making them amongst the largest known ...

Tuzoia carapaces are abundant at the Burgess Shale and other open marine environments (e.g. Kaili Biota [82,83]), but other soft tissues in these sites are extremely rare. It has been suggested, then, that most specimens in these sites represent moults or carcasses falling from a pelagic community . The taphonomic bias against soft tissues ...

Tuzoia was a diverse genus widely distributed across Laurentia, Bohemia, Siberia, and Gondwana. With at least 14 valid species, it ranks among the most diverse non-biomineralized or lightly biomineralized genera of arthropods known from the Cambrian. Tuzoia was first described in Laurentia Perspicaris Briggs, 1977, three species of Tuzoia Walcott, 1912, and at least two species of Anomalocaris Whiteaves, 1892. A priapulid referable to Ottoia Walcott, 1911a, was also recovered. A comprehensive review of Tuzoia is given.
