Concretion with Grub Fossil

A fun new piece of shiny came out the flames today.  

This concretion is a two piece 999 7.6ozt total pour with a Fossil of a grub inside.  Entirely made up, these two pieces Interlock just like a real concretion would.  

Formed over many years, concretions form around a Fossil in layers, which have to be broken off until you get to the core and reveal the Fossil.  

Just like Christmas morning, you never know what may be inside, there may be a oyster, crab, seed, mussel, or anything else.    

This is the prototype and this is not a sales post, just sharing.  Cheers and thanks for looking.
