Incase you haven't guessed, I'm a BIG fan of Dr. Seuss. Is this really a lungfish poo? There is no way to tell for sure. What I do know is lungfish tooth plates are found in the same area that this coprolite was found.
If you would like to learn about Boris the lungfish and his poop, check out One Fish Poo Fish! It has been a couple years since Boris made a donation. He has grown substantially and promises a new poo very soon. Stay tuned!
