GEOLOGY

Detailed explanation-1: -The rarest form of fossilization is the preservation of original skeletal material and even soft tissue. For example, some insects have been preserved perfectly in amber, which is ancient tree sap.

Detailed explanation-2: -Amber fossils are made when insects or other very small animals become trapped in thick tree sap. The sap hardens over time to become amber, and the body of the animal is preserved intact.

Detailed explanation-3: -Collectors and scientists have found not just bugs entombed in tree resin, but even animals as large as lizards, frogs and salamanders can be preserved in impressive detail. Skin, scales, fur and feathers are just some of the incredibly detailed features found in amber. Insects may be caught having sex.

Detailed explanation-4: -Amber is formed from resin exuded from tree bark (figure 9), although it is also produced in the heartwood. Resin protects trees by blocking gaps in the bark. Once resin covers a gash or break caused by chewing insects, it hardens and forms a seal.

Detailed explanation-5: -Fossils form in five ways: preservation of original remains, permineralization, molds and casts, replacement, and compression. Rock formations with exceptional fossils are called very important for scientists to study. They allow us to see information about organisms that we may not otherwise ever know.
