there are plenty of examples of bones being carved into something else. there was an example of this at manchester museum of an elephant tusk, and carved into it was designs that are similar to that of egyptian hieroglyphs. all of these examples are off deviantart and what people have done themselves. they all look amazing and it must be some skill to craft bone into something else.

my own example of bone being carved into something else. this is something my boyfriend bought me for christmas a couple of years ago. it's a bear carved out of a moose antler. moose is my favourite animal and bears symbolise a calm strength, wisdom and passion. he thought this would be helpful and lucky for me.
