Sara:
We are still diligently working away at our blocks. Last week I became concerned that the density of the rock was preventing my scribe from removing the matrix on the outer edge of bone #4 (the large round surface). So with permission, I soaked a long piece of paper towel and let it rest on the tricky matrix. After 30 minutes it had worked its magic! Much of the matrix was easily removed and the bone was untouched.
As we further our exploration of these blocks we will be sure to update you when we find cool things or use new tactics!
Stay tuned!
