Abstract: More Orsten-type fossils In recent years, 'Orsten-type' fossils, characterized by remarkable preservation of the soft tissue of putative embryos and arthropod larvae, have transformed our view of the early evolution of metazoans. They are termed 'Orsten' fossils from the name of the oily alum shale deposits in Sweden where they were first found; similarly fine preservation has since been found elsewhere. Now, importantly, elsewhere includes the Lower Cambrian in China. Fossils of 'eucrustacea' — crustaceans of modern aspect — are common in the fossil record from around 500 million years ago. Newly unearthed Orsten-type fossils from China include the earliest known eucrustacean in exquisite three-dimensional detail, significantly extending the fossil record of this group.
