Tuzoia

Tuzoia is recovered as an hymenocarine, but its body plan suggests that several isoxyid traits were retained from the stem-euarthropod ancestor or, alternatively, appeared convergently. ...

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.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.Tuzoia dunbari is a species of . EOL has data for one attribute..

Since then, Tuzoia has been found in numerous Burgess Shale-type deposits, representing one of the most widespread arthropods of the era [24,25]. 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 ...
