Ammonite (with rare soft-tissue preservation)3D Model
Sigaloceras (Catasigaloceras) enodatum is an Middle Jurassic macroconch ammonite with rare soft-tissue preservation. The model show an internal mold split from the shell from the Lower Callovian (Calloviense Biozone) Kellaways Sand Member of Claydon Pike pit, Fairford, Gloucestershire, UK. The specimen was investigated using a new integrative approach of combined neutron tomography and X-ray microtomograph. This is model represents the first extensive 3D-preservation of ammonite soft tissues in the body chamber documented through CT as reported in:
