Here we have just a few different types of coprolites found in the Niobrara Formation. Of course there are many more. All of these were found by Ramo Decker.
If you would like to take a closer look at some of these coprolites, click on the links below:
Bum Bananas: Two similar coprolites with no inclusions make pretty fine eyebrows.
Rectal Runt: This unusually shaped coprolite makes a good nose when making poo pictures.
Western Interior Seaway Scroll: Scroll coprolites can look a little like hotdogs (with bun). They can also be used to make a funky mouth.
