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: -The Fossil Record 1. Fossils are the preserved remains or evidence of once-living organisms. 2. All the fossils ever discovered on Earth make up the fossil record.
Detailed explanation-3: -Fossils are typically made from sedimentary rock rather than igneous or metamorphic rock. Metamorphic rock and igneous rock are found beneath Earth’s surface. Since organisms die on Earth’s surface, they are more likely to be covered by sediment, therefore creating a fossil out of sedimentary rock.
Detailed explanation-4: -The National Fossil Collection contains over 40 million fossil specimens. The collection is about 64% fossil invertebrates and microfossils, 18% fossil vertebrates, and 18% fossil plants by volume. These fossils and rock samples record the history of life on Earth over the last 3.5 billion years.
