Beyond the game
The real Entelognathus
Entelognathus was an armored jawed fish with a combination of facial bones important for understanding the origin of modern jaw structures. The small head can carry a much larger evolutionary story.
The pattern of its jaw and cheek bones is important for comparisons with later jawed vertebrates. Its facial skeleton makes the fossil significant beyond its overall armored-fish appearance.
