(Fossils that really aren't!)

Fossils that look like something else


   Those on this page are not really pseudofossils, but are fossils resemble other fossils. For example, horn corals may look like claws, teeth or vertebrae (backbones). Honeycomb coral appear to be petrified honeycomb or wasp nests. This is where learning about the age of the rock where the fossil was found is very important. A dinosaur claw around the Falls area is most likely a horn coral. Dinosaurs are 200 million years younger than the rocks at the Falls!


                    Not a claw or tooth - a Devonian horn coral                         Not a vertebra - a Silurian horn coral
