An endemic sapotaceous tree Calvaria major found on the island of Mauritius is nearly extinct because its seeds apparently required passage through the digestive tract of the now-extinct dodo Raphus cucullatus to overcome persistent seed coat dormancy caused by a specially thickened endocarp.
在毛里求斯岛上发现的一种地方性的安息香科乔木 Calvaria major 现已几近灭绝，因为它的种子显然需要经过现已灭绝的渡渡鸟 Raphus cucullatus 的消化道才能克服由特别增厚的内果皮引起的持久种子休眠。
