High-fidelity modular skeletons authenticate a Cambrian origin for Bryozoa

Nature, Published online: 03 June 2026; doi:10.1038/s41586-026-10590-9

Exquisite early Cambrian fossils of Protomelission gatehousei and Dayingomelission hexaclitia preserve soft-tissue anatomy and skeletal microstructure, confirming that these taxa are definitively bryozoans and indicating a deeper origin for the Bryozoa than was first apparent.
