A newly discovered fossil site in South China captures an entire marine ecosystem in recovery, frozen in rock with unprecedented detail. Named the Huayuan biota, the site preserves not just bones and shells, but soft tissues, internal organs, and entire species never seen before. Soft-Tissue Fossils Expose Hidden AnatomyWhat makes the Huayuan site extraordinary is its preservation of biological features rarely fossilized.
