The Snake in the Dinosaur Bone

by Bernardo Cesare, Department of Geosciences, University of Padova, Padova, Italy

Polarized light photomicrograph of a thin section of dinosaur bone collected in Utah, USA.
The image shows a highly porous structure, with pores filled with late chalcedony, and the fossil remnants of the bone tissue, where black dots used to host a single bone cell.
The structure of the bone mimicks a snake ready to bite.
