Tuzoia.

Jul 14, 2015 · Tuzoia typically occurs as laterally (lc) or dorsoventrally (dvc) compacted carapaces or single valves.

In radiodonts, Daley et al. (2013a) reports traces in different carapace elements of Hurdia, comparable to traces found in other non-radiodont Cambrian arthropod carapaces including Tuzoia from the Burgess Shale and a Tegopelte-like arthropod from the Sirius Passet (Mángano, 2011; Mángano et al., 2012; Mángano et al., 2019). Tuzoia is a large bivalved arthropod having a wide geographic distribution in the strata of the Cambrian Series 2 and 3.

Meanwhile, in 1928, an incorrect "head" for Anomalocaris was proposed via the carapace of a crustacean called Tuzoia. Charles D. Walcott collected complete specimens of Anomalocaris nathorsti [now Laggania cambria ] prior to 1917, and the Geological Survey of Canada collected a nearly complete specimen of Anomalocaris canadensis in 1967.of Tuzoia was a single specimen collected from the Burgess Shale (Miaolingian Series, Wuliuan Stage) in British Columbia, Canada, named T. retifera by Walcott in 1912. The stratigraphy of thisTuzoia 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 .

A cladistic analysis indicates that the fuxianhuiid protopodite represents the phylogenetically earliest occurrence of substantial proximal differentiation within stem-group Euarthropoda illuminating the origin of gnathobasic feeding. Euarthropods owe their evolutionary and ecological success to the morphological plasticity of their appendages. Although this variability is partly expressed in ...
