Bradenton, Florida -- The South Florida Museum Museum is celebrating with an exhibit of the world's largest collection of fossilized poop, which is scientifically known as Coprolites.
It's how the museum is celebrating National Fossil Day.
The poop gives paleontologists valuable information about a past animals lifestyle and diet.
The droppings are from a range of animals that are millions of years old, frogs to crocodiles.
At 12:30 p.m. Saturday, visitors can hear a talk from George Frandsen, the curator and owner of the online site Poozeum.
There also will be a fossil hunt and talk on Florida geology.
The museum is open from 10 am. to 8 p.m.
