Sauropod Dinosaur Agatiseret knogle - Fossil knogle - Hadrosauridae (Ingen mindstepris)
Rare polished section of a Sauropod dinosaur bone from the Morrison Formation (Upper Jurassic) of Colorado.
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 wonderful red coloration and the cell structure is very well defined.
Based on the size of the cells as other features of the bone slabs it is almost certainly sauropod in origin.
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bone, sometimes referred to as "gem bone" is fossilized dinosaur bone in which the original fossil material has been replaced by silica.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.
9,1 x 3 x 0,5 cm.
Nice display included
