GEOLOGY

Detailed explanation-1: -The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record.

Detailed explanation-2: -Preserved evidence of the body parts of ancient animals, plants and other life forms are called ‘body fossils’. ‘Trace fossils’ are the evidence left by organisms in sediment, such as footprints, burrows and plant roots.

Detailed explanation-3: -Paleontological resources, or fossils, are any evidence of past life preserved in geologic context. They are a tangible connection to life, landscapes, and climates of the past. They show us how life, landscapes, and climate have changed over time and how living things responded to those changes.

Detailed explanation-4: -Ginkgo biloba (also called the maidenhair tree) is often referred to as a “living fossil, ” because it is the only remaining representative of a perished botanical family (the Ginkgoaceae) and is considered to be the oldest living tree species [1].

Detailed explanation-5: -Fossils are physical evidence of preexisting organisms, either plant or animal. The most common and obvious fossils are the preserved skeletal remains of animals. Other fossils, which are also evidence of past organisms, include leaf impressions, tracks and trails, burrows, droppings, and root casts.
