GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Fossils are pieces of dead animals and plants. – Reality: Dead animals and plants can be preserved in ice, tar pits, or amber. These are called original remains.

Detailed explanation-3: -The preservation of remains of organisms usually occurs in nature as a result of either ice, amber, or tar. Each of these preservation methods prevents decomposers from acting on the organic matter, preserving it in its original state.

Detailed explanation-4: -The most common method of fossilisation is petrification through a process called permineralisation. After a shell, bone or tooth is buried in sediment, it may be exposed to mineral-rich fluids moving through the porous rock material and becomes filled with preserving minerals such as calcium carbonate or silica.
