When I was proposing illustration ideas to the editors of Ranger Rick for their May issue about baby dinosaurs, I suggested that we reconstruct this fossil.

Here's the final oil painting. I chose an orange and cyan color gamut for a weird look, and I used photographic effects, such as lens flares to add a sense of vérité.
I did a series of quick sketches in colored pencil, fountain pen, and watercolor to explore variations of angles, lighting ideas, and value organizations. These sketches were based on a beautiful sculpted reconstruction by Tyler Keillor.
But I wanted to sculpt my own interpretation of it, so I made a maquette out of plasticine modeling clay. I used that because I planned to recycle the material rather than saving it. Note the lens flare effects when it was set up out in real sunlight.
