Euarthropods owe their evolutionary and ecological success to the morphological plasticity of their appendages. Although this variability is partly expressed in ...Tuzoia. Tuzoia is a rare arthropod from the upper to middle Cambrian. This specimen comes from the Balang Formation of China. This piece shows a net-like surface structure and has an enormous size.

Tuzoia was a very large (up to 180 mm long) bivalved arthropod with a nonmineralized domelike carapace strengthened by prominent pointed features and often flanked by a lateral ridge bearing a spiny frill. The reticulate pattern of Tuzoia is comparable with that of present-day crustaceans (e.g., myodocope ostracods) and is interpreted as a ...The observed euarthropod carapaces (Figs. 3d,e and 4) from Taichoute are considerably larger than those described from early- and mid-Cambrian sites [e.g., Balhuticaris 35; Isoxys 36,37; Tuzoia 37 ...

Zhenghecaris, Isoxys, and Tuzoia are interpreted as nektonic animals that probably inhabited the lower level of the water column in shallow shelf settings at depths of perhaps 100-150 m or less.

The Cambrian 'great appendage' arthropod Tanglangia Luo and Hu in Luo et al., 1999, has until now been known from a single species from the Chengjiang biota of southwest China (Cambrian Series 2, Stage 3).

In the taphonomic ...This is a rare arthropod, apparently bivalve, known as Tuzoia that is found from several of the world’s Cambrian Lagerstätten, such as Canada’s Burgess Shale (Tuzoia burgessensis, Tuzoia retifera and Tuzoia canadensis) and China’s Maotianshan Shales (Tuzoia sinensis), and still others from the Eager Formation in Canada and Emu Bay Shale in Australia.Tuzoia is a relatively common non-biomineralized bivalved arthropod from the Guanshan Biota and, stratigraphically, ranges from Cambrian Series 2 through the Miaolingian Series.

Putative stem-group arthropods are relatively rare in the new collections. We have uncovered frontal appendages and lateral flaps of Anomalocaris.
