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. The concept for sedimentary rocks is the same. Older rocks are on the bottom, younger ones are on top. Researchers also used biostratigraphy, which is the study of how fossils appear, proliferate and disappear throughout the rock record, to establish relative ages.

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.

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. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance.
The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ages of rocks and the fossils they host. There are many processes that lead to fossilization, including permineralization , casts and molds, authigenic mineralization , replacement and recrystallization, adpression, carbonization , and bioimmuration.
A fossil normally preserves only a portion of the deceased organism, usually that portion that was partially mineralized during life, such as the bones and teeth of vertebrates , or the chitinous or calcareous exoskeletons of invertebrates.
