The 425-Mb Lingula anatina genome, embryonic and adult transcriptomes and shell proteome identify chitin-synthase and BMP-related components alongside lineage-specific shell proteins. BMP activity at larval mantle margins suggests a shared biomineralization mechanism, but its functional role requires further testing; the shell toolkit differs from vertebrate bone.
