The molecular structure of bone collagen was found to be preserved in Nuragic bone samples several centuries after burial. Enhanced birefringence of bone and dentin collagen fibres observed in polarized light after Sirus red staining was used to demonstrate this fact.
研究发现，努拉吉时期的骨骼样本在埋葬数百年后，其骨胶原的分子结构依然得以保存。Sirius红染色后在偏振光下观察到的骨和牙本质胶原纤维双折射增强现象证实了这一事实。
