Abstract

jats:titleAbstract</jats:title>jats:pThe robust spines and sclerites of the early to middle Cambrian ‘mollusc’ jats:italicWiwaxia</jats:italic> are ubiquitous in suitably preserved deposits, but are strikingly absent from the Chengjiang Lagerstätte (Cambrian Stage 3, Yunnan Province, SW China). Here we provide the first record of jats:italicWiwaxia</jats:italic> sclerites from this rich deposit, extending the record of the genus to the earliest Cambrian Series 2. This reinforces the cosmopolitan distribution of this iconic Cambrian lophotrochozoan and demonstrates the strong faunal continuity that unites distant Cambrian Lagerstätten.</jats:p>
