Some 15 years ago a fossilized lizard the size of a chameleon was uncovered deep in Italy’s Dolomites mountain range. Buried for hundreds of millions of years under sand and clay, Megachirella wachtleri is rewriting reptile history today.

Initially mislabeled as a member of a broader reptile group, scientists writing in the journal Nature have finally discovered that not only is Megachirella a lizard, but that it’s the world's oldest known lizard.
