In this case, Tuzoia 🌮, an enigmatic bivalved arthropod that has been known for over 100 years, gets a full makeover. Paper by myself and Dr. Jean-Bernard Caron at @ROMtoronto and @eebtoronto. Art by Brittany Cheung https://bit.ly/3W1HHuW . 10 Dec 2022 06:26:45The morphology of Tuzoia is reinterpreted in the light of abundant new specimens from the Middle Cambrian Burgess Shale (British Columbia, Canada) and Kaili (Guizhou, China) Lagerstätten.Tuzoia was a very large (up to 180 mm long) bivalved arthropod with a nonmineralized domelike carapace strengthened by prominent pointed features and often flanked by a lateral ridge bearing a spiny frill.In comparison, recent discovery of a large frontal appendage in Tuzoia supports its predatory habit (Caron et al., 2010). Vannier et al., 2006, Vannier et al., 2007 questioned a "nektobenthic" lifestyle for Tuzoia and preferred a free-swimming lifestyle in the lowermost levels of the water column.Po čem muži touží 2.

Diagrammatic reconstruction of Tuzoia. Diagrammatic reconstruction of Tuzoia in ventral view (a), with the carapace corresponding to T. burgessensis, this view is a diagrammatic reconstruction that emphasizes the boundary between the cephalothorax and the trunk. The orientation of the cephalothoracic appendages emphasizes this differentiation, but their orientation was probably ...Abstract The morphology of Tuzoia is reinterpreted in the light of abundant new specimens from the Middle Cambrian Burgess Shale (British Columbia, Canada) and Kaili (Guizhou, China) Lagerstätten. … Expand. 57.

Figure 8.4 in Robison & Richards (1981). 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 ...The large, unnamed Tuzoia species from the Emu Bay Shale has stalked compound eyes that are ovoid to round and 6-9 mm in diameter: very similar to the fossil eyes described here. However, no detailed structure of the visual surface is preserved in the articulated eyes of Emu Bay Shale or Burgess Shale Tuzoia specimens.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.You are free: to share - to copy, distribute and transmit the work; to remix - to adapt the work; Under the following conditions: attribution - You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Since then, Tuzoia has been found in numerous Burgess Shale-type deposits, representing one of the most widespread arthropods of the era [24,25].The morphology of Tuzoia is reinterpreted in the light of abundant new specimens from the Middle Cambrian Burgess Shale (British Columbia, Canada) and Kaili (Guizhou, China) Lagerstätten.
