This is a Dunkleosteus 3D printable model, it would be fun if you can print it and coloring yourself. My color rendering images you see on the page ain't good enough...
Dunkleosteus is an extinct genus of large arthrodire fish that existed during the Late Devonian period, about 382–358 million years ago.
Here is a model that I spent quite some times to draw. I found many reference for sculpting and studied it a lot. I saw some Dunkleosteus figurines or toy on Amazon but didn't really like their detail, so I decided to make 3D model on my own.
It's a large size 22cm in length but you may scale it down in your ideal sizes.
