Look at the two images and imagine how the entire fossil might look.
The two images are slices through the fossil, as if it were split in half. It is a rare fossil in this German limestone (which is Jurassic in age), although it is very common in the limestone bedrock (which is Ordovician in age) that the library was built upon. In fact, this group of fossils is the state fossil of Kentucky . Can you guess the original shape of this fossil from the pictures?
