Dawn of segmented bilaterians unveiled by soft-bodied fossils in microbial pseudomorphs from the Basal Cambrian

This paper describes the discovery of segmented bilaterian fossils from the lowermost Cambrian, preserved as microbial pseudomorphs, indicating a significant diversification during the Ediacaran-Cambrian transition.

An extinct clade sister to Eumetazoa: On the phylogeny of the Cambrian chancelloriids

This study describes new fossils of chancelloriids, revealing their unique body plan and suggesting they are a basal clade sister to eumetazoans.

Basal Cambrian soft-bodied segmented bilaterians preserved as microbial pseudomorphs

This study identifies microbial pseudomorphs as the earliest three-dimensional body fossils of segmented bilaterians from the basal Cambrian, revealing a diversified bilaterian world.
