Ooooh yeaaah, nothing like a fossilized saber tooth tiger head and neck embedded in your marble! (But all glass of course.) SWEEET!! The one is SO well done, I'm having a hard time letting go of it. Very large and impressive, and it's also got an awesome spacey vortex behind the fossil. Love, LOVE that huge tooth, ha. One of those 'talk-of-the-town' marbles!
