Part of a jawbone of the 422-million-year-old fossil bony fish Lophosteus, visualized with a high-resolution X-ray technique. On the right, the surface of the jawbone is shown in gray. In the middle, exposed teeth are highlighted in gold and dermal odontodes in shades of purple, pink and red. On the left, the bone itself is made transparent, revealing internal blood vessels and pulp cavities, shown in blue and green, as well as the embedded teeth and dermal odontodes. Credit: Chen et al.
