From: Arthropod entombment in weathering-formed opal: new horizons for recording life in rocks

Insect entombed in the opal studied here. 3D surface reconstruction (top) and a microphotograph (bottom). The 3D reconstruction has been performed by X-ray microtomography. The fossil is clearly visible within the near-transparent opal (named “Beverly”). Photo by B. Rondeau and 3D reconstruction by P. Lhuissier.
