One can learn more at the German fossil site steinkern.de. The site is in German but use a translate.google.com to help figure out what is being said if you do not understand the language. I did learn that der steinkern apparently means "the stone core".
foraminifera.eu for bringing the matrix the fossil was in and paper guide to the fossil collection area.
I tried to prep this with an engraver to remove large matrix sections and then a needle for the finer parts. The matrix is soft and easy to remove but as I found out must be done with a delicate touch. As a result I knocked the center whirl out. It retrospect, more care should have been taken and I should have consulted the Preparation and Recovery section of steinkern.de.
