ABSTRACT=<p>The Guanshan Biota (Cambrian Series 2, Stage 4) is a typical Burgess Shale-type biota and is one of the most significant Cambrian Konservat-Lagerstätten from China. <italic>Tuzoia</italic> is a relatively common non-biomineralized bivalved arthropod from the Guanshan Biota and, stratigraphically, ranges from Cambrian Series 2 through the Miaolingian Series. Based on new specimens from the Longbaoshan Section of the Wulongqing Formation, this study distinguished and described in detail the <italic>Tuzoia</italic> in the Guanshan Biota. Supplemental details about the larval stage of Tuzoia tylodesa were obtained, and the ontogenetic pattern of <italic>T. tylodesa</italic> was revised. The confirmation of the presence of <italic>Tuzoia retifera</italic> and the first report of <italic>Tuzoia cf. canadensis</italic> in the Guanshan biota, as well as the confirmation of the presence of <italic>T. retifera</italic> and the first report of <italic>T. cf. canadensis</italic> out of Laurentia (in Gondwana), indicated that species communication between paleogeographic plates is possible.</p>
