Tuzoia is represented by an incomplete specimen of T. cf. manchuriensis (Supplementary Fig. 3I). Finally, a single specimen of an incomplete trunk bearing reniform digestive glands with ramified diverticula (Supplementary Fig. 2A and B), together with another, incomplete arthropod with at least 10 segments, suggest the presence of …

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 structuresassigned to Herpetogaster. New specimens of the sponge Leptomitus zitteli, the bivalved arthropod Tuzoia, and the chordate Emmonsaspis cambrensis provide additional information on those taxa, and multiple specimens allow a bivalved arthropod,Vermontcaris montcalmi newgenus,newspecies, tobe described.

May 1, 2021 · This widespread distribution resembles that of nektonic Peytoia, which occurs across Laurentia (Daley et al., 2013a; see also Pates et al., 2018), South China (Liu, 2013 our unpublished data) and Baltica (Daley and Legg, 2015) and, to some extent, that of the presumed pelagic Isoxys and Tuzoia (Vannier and Chen, 2000; Vannier et al., 2007).

A comprehensive review of Tuzoia is given. Some specimens from Early Cambrian sections are replaced by hematite, resulting in iron staining similar to that in such other Early Cambrian soft-bodied faunas as the Kinzers Formation in Pennsylvania. Some taxa in the Comet Shale, and in other Early and Middle Cambrian soft-bodied faunas, …

Dec 7, 2022 · These traits suggest that Tuzoia swam along the seafloor and used its spinose legs for predation or scavenging. Tuzoia is retrieved by a Bayesian phylogenetic analysis as an early mandibulate hymenocarine lineage, exemplifying the rapid diversification of this group in open marine environments during the Cambrian Explosion.
