Halysites 'chain coral' from Silurian in Wisconsin, acid treatment

[traveltip1]

I found this rock containing a Halysites 'chain coral' in the Silurian of Wisconsin.

I soaked it in diluted muriatic acid for a few hours to partially dissolve the matrix and reveal the silicified coral fossil.

Photos are before and after acid treatment.

Wow! That acid treatment certainly produced a beautiful specimen. There are few things as lovely as Halysites. Congratulations and thanks for sharing.
