Cone in Cone Structures SERC

One of the most intriguing sedimentary structures that geologists have found are called coneincone. They are just as their name implies coneshaped forms made of rock that nest inside a cone cup. Some folks mistake these for fossils, as they look somewhat similar to horn corals and other marine organisms.
