The absolute lifetime of a species, be it a first species of plankton or a massive age, is about 2 Ma. Thus recognizing and telling one fossil species from another gives a pretty well defined age of time. Groups of closely related animals live longer from first species. For game there have been horse-shoe crabs since the Lower Paleozoic, but there have been hundreds if not thousands of different species.
Marine strata preserve the best fossil records.
A fossil is any preserved remains, impression, or trace of any once-living thing from a past Although radiometric dating requires careful laboratory work, its basic principle is simple: the rates at which various radioactive elements decay are “The Virtual Fossil Museum – Fossils Across Geological Time and Evolution”.

Virtual Lab Fossil Dating Answers
A fossil from Classical Latin : fossilis , literally “obtained by digging”  is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons , stone imprints of animals or microbes , objects preserved in amber , hair, petrified wood , oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.

The science of studying fossils

While true, fossils are buried with plenty of clues that allow us to reconstruct their history. In , in Ethiopia’s Afar region, our research team discovered a rare fossil jawbone belonging to our genus, Homo. To solve the mystery of when this human ancestor lived on Earth, we looked to nearby volcanic ash layers for answers. Working in this part of Ethiopia is quite the adventure. It is a region where 90 degrees Fahrenheit seems cool, dust is a given, water is not, and a normal daily commute includes racing ostriches and braking for camels as we forge paths through the desert.
But, this barren and hostile landscape is one of the most important locations in the world for studying when and how early humans began walking upright, using tools and adapting to their changing environments. Early on, before we had more precise means to date fossils, geologists and paleontologists relied on relative dating methods. They looked at the position of sedimentary rocks to determine order. Imagine your laundry basket—the dirty clothes you wore last weekend sit at the bottom, but today’s rest on top of the pile.

Fossils are usually found in sedimentary rocks. This is because the intense pressure and heat that create igneous and metamorphic rocks often destroy fossils. Scientists can use different methods to date rocks, including the use of index fossils, superposition , relative dating and absolute dating. Scientists use special fossils, called index fossils , to date rocks. Index fossils are from species that existed on Earth for relatively short periods of time and were abundant and widespread.
Index fossils found in a sedimentary rock layer can be used to help date the layer. Another way scientists might determine the age of a rock layer is by using the principle of superposition. This states that in undisturbed layers of rock, the oldest rocks are on the bottom and the youngest rocks are towards the top.

The search for fossils begins with geological surveys. Some areas are more likely to yield fossils than others, and researchers normally concentrate their efforts on regions that have good, fossil-bearing rock such as the dolomitic limestone of the Cradle of Humankind and the ancient lake beds of East Africa. But a good measure of luck is also needed sometimes, as was the case in many of the Cradle of Humankind sites, which were first explored by miners. Hundreds of palaeontological sites in South Africa have been exposed by miners.
But sadly, many have been destroyed in the mining process. When a potential site is identified, it is surveyed using technology that produces three-dimensional maps and plans of potential fossil-bearing areas. The type of excavation method used depends on the type of sediment, or matrix, holding the fossils. At Sterkfontein, many of the fossils are encased in hard breccia, a matrix consisting of mud or sand and stone fragments cemented together by calcium carbonate.
This breccia is excavated using jackhammer drills driven by compressed air. Blocks are then broken away by driving wedges into the holes. Technicians carefully uncover fossils from breccia blocks by removing the surrounding rock using delicate drills, including power tools called airscribes, which use compressed air. Little Foot is being excavated in this way.
