鸭嘴海豆芽的 4.25 亿碱基对基因组、胚胎和成体转录组及壳蛋白组识别出几丁质合酶、BMP 相关组分与谱系特异壳蛋白。幼体外套膜边缘的 BMP 活性提示可能共享生物矿化机制，但其功能仍需进一步检验；这套成壳组分不同于脊椎动物骨骼。

A 425-Mb Lingula anatina genome sequenced from male-gonad DNA of adults collected at Kasari Bay, combined with RNA-seq spanning embryonic stages and adult tissues and a proteome of adult shells; these are present-day samples, not evidence for lineage origin time.

现生鸭嘴海豆芽基因组、分期转录组和贝壳蛋白组记录了一个磷酸盐壳生物矿化工具箱样本；它们不证明形态停滞或谱系起源时间。
claim:taxon:lingula-anatinaLuo 等记录了 7 月和 8 月在笠利湾按精确坐标采集的现生怀卵鸭嘴海豆芽成体，因此 0 Ma 只表示该当代采集，不为谱系起源、化石延限或形态停滞定年。
