The Cambrian 'Explosion', half a billion years ago, is regarded as one of the most important events in the history of the Earth, when most major animal groups first appear in the rock record, and for which South Australia has recently become a significant source of spectacular fossils. However, important questions remain regarding their Ediacaran roots, the speed of evolution at the time, and the environments in which the radiation took place. Studying the fossil evidence in the light of present-day ecological frameworks, and in comparison with modern behavioural and morphological analogues, as well as living relatives, can help us better assess our understanding of this first radiation of animals.

十亿年前的寒武纪“大爆发”被认为是地球历史上最重要的事件之一，当时大多数主要动物群首次出现在岩石记录中，南澳大利亚最近已成为壮观化石的重要来源。然而，关于它们的埃迪卡拉根源、当时的进化速度以及辐射发生的环境仍然存在重要问题。根据当今的生态框架研究化石证据，并与现代行为和形态类似物以及活着的亲戚进行比较，可以帮助我们更好地评估我们对动物的第一次辐射的理解。
