Perspicaris Briggs, 1977, three species of Tuzoia Walcott, 1912, and at least two species of Anomalocaris Whiteaves, 1892. A priapulid referable to Ottoia Walcott, 1911a, was also recovered. A comprehensive review of Tuzoia is given. Some specimens from Early Cambrian sections are replaced by hematite, resulting in iron staining similar to that ...718 HU ShiXue et al.

He collected many more specimens after this publication that were later described in detail by Resser (1929). Resser designated ten different species of Tuzoia, including specimens from the Burgess Shale, the Eager Formation of ...Hyolithides preserved in coprolites from the Chengjiang Biota and associated with a Tuzoia carcass from the Balang Fauna reveal the fluid feces consuming and scavenging strategies of this group ...Tuzoia is a large bivalved arthropod having a wide geographic distribution in the strata of the Cambrian Series 2 and 3.

The largest Emu Bay Shale Tuzoia specimens with circular eyes preserved in situ show that these visual organs do not reach more than 9 mm in diameter (21, 26), and even the biggest Tuzoia carapaces from this deposit would not be able to accommodate acute zone-type eyes more than 3 cm in diameter.Adult Moniezia species measure up to 600 cm in length and 15 mm (M. expansa) or 25 mm (M. benedeni) in width.The scolex of both species has four circular suckers, but no rostellum or hooks. Each mature segment contains two sets of reproductive organs but only one uterus. At the posterior margin of each segment of M. expansa there is a transverse row of discrete inter-proglottidal glands; in M ...Tuzoia属到目前为止已描述发表的种共计21 个，经过整理，修订后还有15种及本文描述的1新 种共计16种有效。现将种名、产地和时代列述如 ….

The results of the more conservative dataset (dataset 2) are shown as an inset containing only the closest allied taxa to Tuzoia (see electronic supplementary material, figure S6 for full tree).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 ...

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
