Frogs, toads and other amphibians are very rarely found as amber inclusions for several reasons: they’re usually larger than most insects and as such have a greater amount of muscle power available to extract themselves from the primordial goo, their moist skin is less likely to stick to the sap, and their usual habitats aren’t in the trees.

Lizards

The Cretacegekko burmae gecko is a 100-million-year-old gecko, preserved in cretaceous amber. The fossil remains from the amber include a plethora of plant and invertebrate remains but vertebrate fossils are very rare. WWF calls this extinct species "one of the most significant findings" because it is the oldest fossil gecko species known to science. It was discovered in an amber mine in the Hukawng Valley in Himalayan regions of far northern Myanmar.

Lizards locked in amber are both extremely rare and extremely valuable: Gazing at a vertebrate trapped in ancient amber is the closest thing to stepping into a time machine.
