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.

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

The paper describes a new Cambrian ecdysozoan species, Beretella spinosa, and suggests that ancestral ecdysozoans may have been non-vermiform.
