Beautiful result after a challenging transfer-preparation. Note the reddish color!

Tuzoia is a large bivalved arthropod having a wide geographic distribution in the strata of the Cambrian Series 2 and 3. One species, Tuzoia bispinosa, is known from abundant material in the Kaili Biota (Cambrian Series 3, Stage 5).Based on 168 specimens from near Balang Village, Jianhe County, Guizhou Province, China, six ontogenetic stages of this species can be distinguished.

Each type (lc or dvc) emphasizes particular aspects of the morphology (e.g., spiny lateral ridge, ventral margin) that were often interpreted as specific differences by previous authors. A revision of Tuzoia validates only 7 of the 23 named ...The origin of mandibulates, the hyperdiverse arthropod group that includes pancrustaceans and myriapods, dates back to the Cambrian. Bivalved 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 ...

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. 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).

Isoxys and Tuzoia are are 2 of these that are about 10 cm long and look like clams, but they are crustaceans like shrimps with a head shield that encloses the whole body of the animal and is hinged along the back. There is disagreement about where they belong, some thinking they should be assigned to the phyllocarids (leaf-shrimps) and …

D. anima, as well as the newly reported Tuzoia. sp. from the Fandian biota, represent the oldest occurrence of Tuzoiidae, extending its stratigraphic range to Cambrian Stage 3 and expanding the palaeogeographical distribution of the group to the northern border of the Yangtze Platform.In the ecological Tuzoia garden hypothesis, the bacterially enriched surface of carapaces provides opportunities for intricate ecologic interactions among trophic levels. In the taphonomic ...Arthropods (Redlichia, Palaeolenus, Isoxys, Tuzoia) and brachiopods (Eoobolus, Neobolus, Schizopholis, Palaeobolus and Nisusia) are the most diverse components of the fauna (Table 1, Fig. 3 ...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.

The others are Pectocaris (which I should update), Jugatacaris, Odaraia, Fibulacaris and Pakucaris.
