Bone is an important material in many scientific disciplines because
of its unique structure-property relationships, which are
intrinsically dependent on its nanoscale components, bioapatite and
collagen. As a living tissue, bone has evolved over hundreds of
millions of years, and most vertebrates are now extinct. However, the
vast majority of the relevant literature has engaged only modern bone
tissues, neglecting the deep time perspective. Why?
