Tuzoia.

Dec 7, 2022 · Tuzoia was one of the original species described from the Cambrian (Wuliuan) Burgess Shale, known only from its distinct reticulated large carapace valves and variable spines [22,23]. Since then, Tuzoia has been found in numerous Burgess Shale-type deposits, representing one of the most widespread arthropods of the era [24,25].

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 ...

Museum-quality original Chengjiang-type fossil specimen of Arthropod Tuzoia is an extinct genus of large bivalved arthropod .

It is possible that it shared habitat with other large swimming arthropods, such as Isoxys and Zhenghecaris ...
