STRIKING HANDMADE PETRIFIED DINOSAUR BONE REDS, WHITE, BROWN.  BRIGHT COLORS. SET IN STERLING SILVER WITH 18" STERLING SILVER CHAIN.  28.7 X 12.0 MM

Agatized fossilized dinosaur bone is extremely rare as it was petrified with crystals during the fossilization process. This process preserved the original cell structure of the dinosaur in the fossil, which can be found in its original bone shape.

Fossils take over 10,000 year to develop. The definition of a fossil is a trace left from a death that happened over 10,000 years ago. All bones take at least 10,000 years to petrify.

It is often stated in the paleontological literature that the chance an animal will become fossilized is "one in a million." This number is meant to be taken figuratively, the point being that the odds of surviving the rigors of deep time are extremely remote. Nevertheless, all field paleontologists know that the earth is biased when it comes to giving up its dead--the odds of an animal being preserved and consequently exhumed are much greater in some settings than others.
