This Extinct Monitor Lizard Had Four Eyes

Four eyes are better than two, or at least that was the case for a monitor lizard that lived close to 50 million years ago.

This image depicts a reconstruction of what the extinct monitor lizard might have looked like. The parietal and pineal foramina are visible on the overlaid skull. | Senckenberg Gesellschaft für Naturforschung/Andreas Lachmann/Digimorph.org
