Polished Agatized Dinosaur Bone Slab - 5.3"

This is a large slab of agatized dinosaur bone that has been polished on both sides to expose the inner cell structure. It has a dark coloration with some blues and greens as you move towards the center of the bone with a well defined cell structure. This bone was collected near Bouarfa, Morocco which would encompass the Late Cretaceous, Kem Kem Beds. Based on the size on the features of the slabs it's sauropod in origin. There is currently a single described sauropod dinosaur in the formation, the Diplodocoid Rebbachisaurus garasbae.

The slab itself is 5.3x3.8" and varies in thickness slightly up to about .5" Both sides have been polished to a mirror like finish and it comes with an acrylic display stand.

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bone, sometimes referred to as "gem bone" is fossilized dinosaur bone in which the original fossil material has been replaced by silica.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.
