010026 - Nicely Preserved Knightia Fossil Fish Eocene Green River Fm, Wyoming (USA) Pterosaur manufactured through synthetic resinsMagnificent specimen with detailed preservation. You can see the whole bone structure as well as details of the jaw and its small teeth. From this type of fossilization, through taphonomy, many aspects of the original paleoenvironment can be learned. This type of preservation only occurs under certain very special circumstances, in the bottoms of lakes, with anoxic conditions, for example.
