In 2010, I
posted some images of this type of microfossils found in Spergen Hill, Indiana, USA. This place is a type locality where this particular species was found and named in the literature first. Since my cousin Kenny recently acquired a new Amscope microscope I asked him to image some of these fossils for this posting.
These images are of foraminifera fossils from the Salem Limestone of Washington County, Indiana, USA. These creatures are called
Globoendothyra "Endothyra" baileyi and existed 360-325 million years ago (Mississippian Period).
A very good write up on this particular fossil can be found on the Fossil Forum site written by user dshamilla.

Thanks to Kenny for the images.
