Juvenile amber (copal) — It is in amber that once animated insect life is most exquisitely captured. With amber, you see 2 types of fossils: tree resin from a plant and the insect. Amber has been fossilized since the end of the cretaceous period some 65 million years and is still being made today by geologic process. Large amber deposits are found in certain areas on the planet (Dominican Republic, Baltic Sea, Mexico, and Burma ) many types of life forms have been found in amber such as leaves, twigs, a wide variety of insects, some marine animals, and even certain land animals. Most of these animals were alive when they were entombed in the tree sap then over time the sap hardened to make the amber.
