Thanks to Mary Ann for the fossils and my cousin Kenny for cleaning them up using sand/air abrasive cleaning. Unfortunately, I did not take any before pictures but they looked like Mexican wedding cookies (a little mound covered powdered sugar).

Hemiaster (Sea Urchin) Fossil

Echinoid fossil called Hemiaster whitei found in Tarrant County, Texas. This Cretaceous period (102 million years ago) creature is found in the Goodland formation.

Thanks to Shamalama for the fossils and my cousin Kenny for cleaning these approximate 2 cm in diameter fossils up.  I need to look back and see if I took any pictures of what these looked like before cleaning.  Click on pictures to see larger version.

Foraminifera of Kobrow

The first three pictures of the foraminifera is called Elphidium subnodosum (also known as Elphidiella) found in Sternberger Kuchen at Kobrow, Germany. Creature existed in the Upper Oligocene Epoch of the Paleogene Period (65-28 million years ago).  Images all magnified 40x by a microscope.

Thanks to Michael Hesemann at the German website http://www.foraminifera.eu for these specimens.

UPDATED: Thanks to Howard and Michael for the corrected identifications.
 

These next two foraminifera fossils are Palmula obliqua.

These next two images are Lenticulina sp.

These next two fossils are earstones of fish called otoliths (as identified by Michael's comment).  Learn more about otoliths at this link.
