The robust spines and sclerites of the early to middle Cambrian ‘mollusc’ Wiwaxia are ubiquitous in suitably-preserved deposits – but are strikingly absent from the Chengjiang Lagerstätten (Cambrian Stage 3, Yunnan Province, southwest China). Here we provide the first record of Wiwaxia sclerites from this rich deposit, extending the record of the genus to 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.
