Tuzoia sp. Middle Cambrian Marjum Formation House Range, Millard County UT, USA. Excellent 56mm phyllocarid on 150mm slab. Branchiocaris is a genus of the Subclass Phyllocarida, a group of crustaceans known primarily from their bivalved carapaces. It lived during the Middle Cambrian with its remains documented from North America and China.The eyes in Tuzoia sp. were more than twice as large to those in Tuzoia australis and show evidence of a visual cortex, but were located in a similar position, at least in dorsoventral specimens (EXPLANATION OF PLATE 4 , EXPLANATION OF PLATE 6 ).The Guanshan Biota (Cambrian Series 2, Stage 4) is a typical Burgess Shale-type biota and is one of the most significant Cambrian Konservat-Lagerstätten from China.

The Lower Cambrian Emu Bay Shale contains in its lower part, exposed near White Point on the north coast of Kangaroo Island, an unusual assemblage of phyllocarid crustaceans (Isoxys communis sp. nov., Tuzoia australis sp. nov.) and annelid worms (Palaeoscolex antiquus sp. nov., Myoscolex ateles gen. et sp. nov., Vetustovermis planus gen. et sp. nov.), together with Estaingia and redlichiid ...

Abstract: Abundant material from a new quarry excavated in the lower Cambrian Emu Bay Shale (Kangaroo Island, South Australia) and, particularly, the preservation of soft‐bodied features previously unknown from this Burgess Shale‐type locality, permit the revision of two bivalved arthropod taxa described in the late 1970s, Isoxys communis and Tuzoia australis.

Free shipping for many products!One of the most common and globally distributed Cambrian bivalved arthropods is Tuzoia. Originally described in 1912 from the Burgess Shale based on isolated carapaces, its full anatomy has remained largely unknown.Tokummia has a cylindrical body, with the anterior half covered by a 8.78 cm (3.46 in) long bivalved carapace. At the front of the animal, there are a pair of antennae, possible eyes, mouthparts ( mandibles, maxillule and maxilla) and prominent pincer-like maxillipeds. These shows the oldest record of arthropod pincers.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 ...

Tuzoia (from Mount Tuzo, a mountain in the Canadian Rockies) is an extinct genus of large bivalved arthropod known from Early to Middle Cambrian marine environments from what is now North America, Australia, China, Europe and Siberia.
