Mexican scientists are studying a complete fossil of a lizard that lived some 23 million years ago and whose soft tissue remains have been preserved in amber. Amber means hard translucent fossilized resin produced by extinct coniferous trees of the tertiary period, typically yellowish in color.The small piece of fossil resin, which is in the shape of a trapezoid and entombs the skeleton, was found several months ago in the Simojovel amber deposits of the northern part of the southeastern state of Chiapas.

Amber often remains of plants and animals, but it is rare to find complete vertebrates such as this lizard, preliminary identified as a new species of the genus Anolis. The specimen measuring approximately 4.5 centimeters by 1.3 centimeters was a complete and articulated animal that also preserves remains of soft tissue and skin.
