Amber is valued for its botanical and animal inclusions that are trapped by the sticky resin as it flows fulfilling its role in protecting the plant. Of course, other life is captured including microscopic bacteria that often produce gas bubbles, and various fungi. Both the botanical and animal inclusions not only add beauty, but also are of potential scientific value in the study of taxonomy and evolution. Animal inclusions are usually invertebrates, specifically arthropods, and only extremely rarely a vertebrate such as a small lizard. Fossil resin inclusions are overwhelmingly insects, which naturally follows from the resin’s evolutionary origin as a physical means of protecting plants from insect pests.
