The latest addition to the group, Cambroraster falcatus, was recently described from the Wuliuan Burgess Shale, and is characterized by a unique horseshoe-shaped central carapace element. Here we report the discovery of Cambroraster sp. nov. A, a new species from the Cambrian Stage 3 Chengjiang Lagerst{\"a}tte of South China. The new occurrence of Cambroraster demonstrates that some of the earliest known radiodonts had already evolved a highly derived carapace morphology adapted to an essentially eudemersal life as sediment foragers.}, url = {https://www.cambridge.org/core/journals/geological-magazine/article/occurrence-of-the-eudemersal-radiodont-cambroraster-in-the-early-cambrian-chengjiang-lagerstatte-and-the-diversity-of-hurdiid-ecomorphotypes/D4AD12D56D158EC7AFD9ACBA499B6A7C}, author = {Liu, Y. and Lerosey-Aubril, R. and D.
