20th Annual Smithsonian Magazine Photo Contest Natural World
The Snake

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 is intriguing and scary: can you see the snake in the centre of the image? Width of view 2,7 mm.
