The report of Anomal-ocaris from the Emu Bay Shale (McHenry and Yates 1993) was followed by the recognition of two species in that genus (Nedin 1995a), one of which was formallyNov 13, 2009 · 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 ). Tuzoia is an unusual genus of bivalved arthropod that has been classified as a phyllocarid or perhaps as a member of a yet-to-be-named group including other odd Early-Middle Cambrian arthropods. It's known from North America (British Columbia, Utah, Pennsylvania), Europe, China, and Australia. Yeah, it got around.Download scientific diagram | Artistic reconstruction of Tuzoia.

Recent descriptions of soft parts show that the frontal appendage is similar to that of some megacheiran, or “great appendage,” taxa such as Leanchoilia, Alalcomenaeus, and Yohoia (Vannier et al., 2009; García-Bellido et al., 2009a).Tuzoia is a relatively common non-biomineralized bivalved arthropod from the Guanshan Biota and, stratigraphically, ranges from Cambrian Series 2 through the ...In comparison, recent discovery of a large frontal appendage in Tuzoia supports its predatory habit (Caron et al., 2010). Vannier et al., 2006, Vannier et al., 2007 questioned a "nektobenthic" lifestyle for Tuzoia and preferred a free-swimming lifestyle in the lowermost levels of the water column.Tuzoia – a rare and bizarre Arthropod from the Cambrian of China.

The reticulated pattern on its carapaces likely increased the strength of the valves while remaining lightweight, which suggests, along with other hints, it was a free-swimming animal.The collections have also produced fossils belonging to two new species: Isoxys glaessneri and Tuzoia sp.
