Maturifusus Gastropod Fossil

This fossil is a Maturifusus (J. Szabó, 1983) gastropod fossil found in the clay pits at Buttenheim located in the state of Bayern (Bavaria), Germany. I think it is located in the Lias lithostratigraphic unit which would date to the Jurassic. Field of view is about 3 mm. 

Thanks to Dieter Ketelsen of Hamburg, Germany for the fossils/matrix. Also I appreciate Michael at foraminifera.eu for bringing the matrix the fossil was in and paper guide to the fossil collection area back in 2012. My cousin Kenny, now that he is retired, was able to study this matrix recently using a microscope. Thanks Kenny for the picture.

Pleuroceras Ammonite - Germany

This fossil is a species of the genus Pleuroceras found in the clay pits at Buttenheim located in the state of Bayern (Bavaria), Germany. I think it is located in the Lias lithostratigraphic unit which would date to the Jurassic. Fossil is about 3 cm wide.

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".

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.
