One species, Tuzoia bispinosa, is known from abundant material in the Kaili Biota (Cambrian Series 3, Stage 5).Based on 168 specimens from near Balang Village, Jianhe County, Guizhou Province, China, six ontogenetic stages of this species can be distinguished.Additionally, we report the presence of bradoriids, Branchiocaris pretiosa, Perspicaris? dilatus, Naraoia? sp., Thelxiope cf.

Each type (lc or dvc) emphasizes particular aspects of the morphology (e.g., spiny lateral ridge, ventral margin) that were often interpreted as specific differences by previous authors.

Anomalocaris has a complex history of description because parts of its body were described in isolation before it was realized they all belonged to the same animal. The frontal appendage of Anomalocaris was described by Whiteaves (1892) as the body of a shrimp. The mouth parts were described by Walcott (1911) as a jellyfish called Peytoia nathorsti.A full body anomalocaridid specimen was ...Tuzoia (Q148514) From Wikidata.

Phylogeny. Classification. Dendrogram. References. The following are two recent classifications of arthropods, one emphasising Cambrian taxa, the other a more generic approach in a recent palaeontological text on insects. It is intended at some point to include our own classificxation scheme, but this has not been done so far due to ...

A 'prototype' of the pelagic food chain is likely to have been established at a relatively early stage of the Cambrian radiation, that probably involved arthropod (e.g. Isoxys, Tuzoia and anomalocaridids; Vannier et al. 2007a) and non-arthropod predators such as ctenophores and chaetognaths (Hu et al. 2007). We see it as a key step that ...TUZOIA BURGESSENSIS, new species. Plate 2, figure 1; Plate 3, figure 1 Comparing this species with T. retifera we first note that it is longer and narrower and that the reticulations of the keel appear to be more numerous and stronger.
