Serpenticone Shell of an Ammonite

3D Model

A 3D model of an Serpenticone shaped shell of an ancient ammonoid, an extinct group of cephalopod that dominated the oceans during the age of the dinosaurs. Researchers at the University of Utah create 3D models and simulations of the variously shaped fossilized shells to understand how they swam. Scanned and modeled by University of Utah AmmLab.
