The specimens were provided by Michael Hesemann of the amazing website (www.foraminifera.eu). I photographed these fossils with an Orion Microxplore MFL-06 microscope and Kodak Easyshare LS743 camera.
These first two pictures appear to be a Palmula obliqua foraminifera. Learn more at this webpage.
This last specimen appears to be Palmula oblonga foraminifera. See this webpage for more info.
