GEOLOGY

Detailed explanation-1: -What is an amber ? This is another type of fossilization where the organism is entrapped in a biologically inert environment and it is preserved wholly. For the insects, which frequently occur in this type of fossilization, “chitinous skeletons are little altered, but the soft inner tissues are missing."

Detailed explanation-2: -Amber can preserve the bodies of many delicate, soft-bodied organisms, such as ants, flies, and mosquitoes. The fossils of bones, teeth, and shells are called body fossils. Most dinosaur fossils are collections of body fossils.

Detailed explanation-3: -Preserved remains are types of fossils where the entirety of an animal, plant, or insect is preserved. These types of fossils can only be created under special circumstances that prevent the decomposition of the creature. Creatures preserved this way have been found in amber, tar, peat, and ice.

Detailed explanation-4: -When an animal becomes trapped in naturally-occurring tar or paraffin, its whole body can be preserved. While paraffin and other waxes can preserve an animal’s soft tissue, substances like tar preserve only hard parts.
