Tuzoia. Things To Know About Tuzoia.

The Cambrian ‘great appendage’ arthropod Tanglangia Luo and Hu in Luo et al., 1999, has until now been known from a single species from the Chengjiang biota of southwest China (Cambrian Series 2, Stage 3).

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 ...Tuzoia. Tuzoia is a rare arthropod from the upper to middle Cambrian. This specimen comes from the Balang Formation of China. This piece shows a net-like surface structure and has an enormous size. The fossil is paper thin and separates extremely poorly from the surrounding rock. As it was found splitting the shale, parts of the fossil were in ...

A cladistic analysis indicates that the fuxianhuiid protopodite represents the phylogenetically earliest occurrence of substantial proximal differentiation within stem-group Euarthropoda illuminating the origin of gnathobasic feeding. Euarthropods owe their evolutionary and ecological success to the morphological plasticity of their appendages. Although this variability is partly expressed in ...

Tuzoia is a relatively common non-biomineralized bivalved arthropod from the Guanshan Biota and, stratigraphically, ranges from Cambrian Series 2 through the Miaolingian Series.

The affinity of Isoxys is uncertain because for a long time it was known only from empty carapaces. Recent descriptions of soft parts show that the frontal appendage is similar to that of some megacheiran, or “great appendage,” taxa such as Leanchoilia, Alalcomenaeus, and Yohoia (Vannier et al., 2009; García-Bellido et al., 2009a).Zhenghecaris, Isoxys, and Tuzoia are interpreted as nektonic animals that probably inhabited the lower level of the water column in shallow shelf settings at ...Perspicaris Briggs, 1977, three species of Tuzoia Walcott, 1912, and at least two species of Anomalocaris Whiteaves, 1892.
