 In the third publication from the international collaboration between **Javier Ortega-Hernández** and Prof. Yu Liu, Yunnan University, China, researchers use microCT on *Cambroraster,* a distant arthropod relative. The study published in *[Geological Magazine](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)* describes the occurrence of *Cambroraster* whose head's carapace bears an uncanny similarity to horseshoe crabs. This finding represents the second instance of *Cambroraster* reported worldwide, as well as the oldest, and indicates that these early euarthropods had acquired a complex benthic ecology (ocean floor or the bottom of a lake in the sediment surface) quite early on during their evolutionary history.
