A 23-million-year-old lizard

A 23-million-year-old lizard was trapped in tree resin during the age of early mammals — and it still has its skin.

 Discovered in the amber mines of Simojovel, Chiapas, Mexico, this tiny creature from the genus Anolis measured less than 2 inches — yet it survived the ages in near-perfect condition, soft tissue, skin, and all, sealed inside fossilised tree resin like a prehistoric time capsule.

 Finding a complete vertebrate in amber is extraordinarily rare.  Insects and plant fragments turn up all the time — but a fully intact lizard with its skeleton and skin preserved?  This, according to scientists, is one of the most remarkable amber fossils ever discovered on the mainland of the Americas. The specimen dates to the Miocene epoch — a time when the world's continents were still shifting, grasslands were replacing forests, and the ancestors of modern mammals were just beginning to spread across the earth.  This little lizard was alive through all of it.  And then one day, it got caught in sticky tree resin — and never left.

 It now sits on display at the Amber Museum in San Cristóbal de las Casas, Mexico, still wearing the same skin it had 23 million years ago.

 Nature's greatest works can be preserved without a museum. Sometimes, a drop of tree resin is enough.
