Nuragic bone collagen retains its molecular structure

Ital J Anat Embryol. 1995 Oct-Dec;100(4):195-202.

Abstract

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.
