1.4" Polished Agatized Dinosaur Bone Slice - Morocco

This is a small slice of agatized dinosaur bone that has been polished on both sides to expose the inner cell structure. This bone was collected near Bouarfa, Morocco which would encompass the Late Cretaceous, Kem Kem Beds. Based on the shape this slice is most likely taken from a partial limb bone.

Agatized bone, sometimes referred to as "gem bone" is fossilized dinosaur bone in which the original fossil material has been replaced by silica. The impurities within the silica is what gives it the color. For example the red coloration of this bone is caused by iron based compounds. Interestingly this silica replacement often happens at a sub-cellular level leaving the internal structures intact.
