Ammonite - Dactylioceras Commune

Ammonite - Dactylioceras Commune fossil from the Jurassic period, approximately 170 million years old.
After I recently created my newest ammonite, I thought I might as well redesign my old ammonite from 2008
Was sculpted in Zbrush and retopologiesed in 3ds Max and Topogun 3. I used Photoshop mostly for texturing and Substance Painter to paint and bake the mesh textures.
