Orthoceras, graphite on Bristol

I wanted  to try something paleontological, so I composed this scene of a little orthoceras (a nautiloid) living among marine plants about 450 million years ago. So many  drawings of life in the Paleozoic era show lots of attacking going on, trying to show the survival of the fittest at work; I wanted my orthoceras to have a moment of peace, so I tucked him safely in some seaweed.
