An international collaboration between researchers at Harvard University and Yunnan University in China uses microCT to study and restudy arthropod fossils from the early Cambrian in the Chengjiang biota in the Yunnan Province of China. Their latest study shows with unprecedented clarity the head morphology of the species Leanchoilia illecebrosa and demonstrates the presence of a labrum thus supporting the hypothesis that megacheirans are distant relatives of modern chelicerates (e.g. horshoe craps, scorpions and spiders).
