2. Material and methods. Tuzoia has been chosen for the present analysis because it occurs in many Burgess Shale localities in the Canadian Rockies and other Cambrian Lagerstätten (e.g. [15,23-26]).Close to 50% (see electronic supplementary material, table S1) of the examined Tuzoia specimens at the Royal Ontario Museum (ROMIP) are associated with biogenic structures.It is thought that Tuzoia species probably lived in the water column, perhaps explaining their great distributions.

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 carapace ornament is essentially identical to the condition in Cordaticaris and to a lesser extent Zhenghecaris , with the reticulate pattern being shared more broadly among many hurdiids, including Hurdia and probably representing an external ornamentation similar to Tuzoia .文中详细描述了云南东部地区早寒武世关山动物群中的典型分子Tuzoia sinensis Pan,对其形态特征做出了补充,通过与相关种的比较与讨论,对其鉴定方法做出了进一步探讨,并基于对壳体表面网格密度的研究推测了T.sinensis的俯视形态图。. 研究发现:T.sinensis的侧脊上分布 ...First animals.
