Fossil Fish

 

The Jurassic Solnhofen Limestone is better known for the fossil bird Archaeopteryx, but as might be expected for a marine sediment, it also contains fossil fish. More here.

Our example is Gyrodus - which because of its shape is also known as the “Moon fish”. It has rounded teeth suggesting its diet was small crustaceans or coral.

Thin sections of teeth from two species of shark are also shown.
