Tuzoia.

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.

A revision of Tuzoia validates only 7 of the 23 named species. Tuzoia is placed tentatively within a group of large bivalved arthropods along with Isoxys and the possible ancestors of Thylacocephala (Lower Cambrian–Upper Cretaceous).

The morphology of Tuzoia is reinterpreted in the light of abundant new specimens from the Middle Cambrian Burgess Shale (British Columbia, Canada) and Kaili (Guizhou, China) Lagerstätten. 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.

Tuzoia is represented by an incomplete specimen of T. cf. manchuriensis (Supplementary Fig. 3I). Finally, a single specimen of an incomplete trunk bearing reniform digestive glands with ramified diverticula (Supplementary Fig. 2A and B), together with another, incomplete arthropod with at least 10 segments, suggest the presence of …Tuzoia canadensis. Tuzoia canadensis was one of the pointier-looking tuzoiids, known from the Canadian Burgess Shale deposits (~508 million years ago).

Its reticulated ornamentation had fairly large polygonal ...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 ...3.Soft anatomy of Isoxys minor. Isoxys minor is the most commonly represented species in the Guanshan fauna, which is widely distributed in the Wulongqing Formation (Cambrian Series 2, Stage 4; Palaeolenus Zoon) at the Shitangshan Section near Gaoloufang and Gangtoucun villages, Kunming City, Lihuazhuang, Yiliang County, Shijiangjun and Sapushan, Wuding County (Luo et al., 2008).Isoxys (meaning "equal surfaces") is a genus of extinct bivalved Cambrian arthropod; the various species of which are thought to have been freely swimming predators. It had a pair of large spherical eyes (which are the most commonly preserved feature of the soft-bodied anatomy), and two large frontal appendages used to grasp prey. The collections have also produced fossils belonging to two new species: Isoxys glaessneri and Tuzoia sp. Among the soft parts preserved in these taxa are stalked eyes, digestive structures and cephalic and trunk appendages, rivalling in quality and quantity those described from better-known Lagerstätten, notably the lower Cambrian Chengjiang ...A revision of Tuzoia validates only 7 of the 23 named species.
