Ancient Coprolite fossils, available in two different sizes. These are… well, interesting objects. Coprolite fossils are fossilised pieces of poo!
They come from a range of animals – usually aquatic animals, including fish and turtles. Some larger pieces are from Dinosaurs, which I might add in a separate listing.
They tend to be quite soft fossils, likely formed in mudstone or similar – as such they do abrade quite easily and I wouldn’t recommend exposing them to water in a fish tank or similar.
Obviously, Coprolites differ widely from one to the next. The photographs used are of a typical looking specimen, but there are many different kinds, shapes, and sizes.
The photographs are just intended to give you a reference to the sort of thing these are.
