Not sure... Giraffe just felt right...
First time I've seen Jigged Bone and been told what it was.
Stabilized means, having a stabilizing agent infused into the piece to strengthen it and help hold it together. CA Glue is often the agent, and a vacuum process is often used to infuse the target piece.
Stabilized Bone, Mammoth Ivory, Turquoise and Spalted Wood are just a few materials you might find out there.

Most of the stabilising processes are trade secrets and not revealed to the general public. I think some of them involve epoxy and pressure.
