Tuzoia is a large, bivalved Cambrian arthropod having a widespread distribution in shallow‐shelf to deeper marine Lagerstätten; stratigraphically it ranges from Cambrian Series 2 through the Miaolingian Series.

Picture (c) J.-B.Caron https://bit.ly/3uyviCS . 07 Dec 2022 19:57:54Bivalved arthropod groups such as hymenocarines have been argued to be early mandibulates, but many species are still poorly known, and their affinities remain uncertain. One of the most common and globally distributed Cambrian bivalved arthropods is Tuzoia. Originally described in 1912 from the Burgess Shale based on isolated carapaces, its ...The largest Emu Bay Shale Tuzoia specimens with circular eyes preserved in situ show that these visual organs do not reach more than 9 mm in diameter (21, 26), and even the biggest Tuzoia carapaces from this deposit would not be able to accommodate acute zone-type eyes more than 3 cm in diameter.Tuzoia is retrieved by a Bayesian phylogenetic analysis as an early mandibulate hymenocarine lineage, exemplifying the rapid diversification of this group in open marine environments during the ...Jul 20, 2019 · In the present study, three species are recognized from relatively deep-water deposits of the Balang Formation (Cambrian Stage 4) of Guizhou, South China: Tuzoia sinensis Pan, 1957, T. bispinosa Yuan et Zhao, 1999 and T. lazizhaiensis sp. nov.
