Each bid is for ONE slide containing the rare remains of Fairy Shrimp coprolites (poop) from the Miocene age Barstow formation of California. These specimens have to be acid etched out of nodules and it is a miracle that any fossil remains of these tiny shrimp even survive.
These nodules were collected 50 years ago and have only recently been prepared. Highly recommended. Images show typical specimens like the ones you will receive.
A microscope is essential to properly view these specimens.
