Dating the fossil record worksheet key
The age of fossils can be determined using stratigraphy, biostratigraphy, and radiocarbon dating. Paleontology seeks to map out how life evolved across geologic time. A substantial hurdle is the difficulty of working out fossil ages. There are several different methods for estimating the ages of fossils, including:. Paleontologists rely on stratigraphy to date fossils. Stratigraphy is the science of understanding the strata, or layers, that form the sedimentary record. Strata are differentiated from each other by their different colors or compositions and are exposed in cliffs, quarries, and river banks.

Background: Fossils are the remains, imprints, or traces of organisms that were once alive. By studying fossils, scientists can learn where, when, and how those.
However, “relative” dating or time can be an easy concept for students to learn. Once they are able to manipulate the cards into the correct sequence, they are asked to key a similar sequencing activity using fossil pictures printed on “rock layer” cards. Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.
Once students begin to grasp “relative” dating, they sir extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth’s history. Idea major concepts are part of the Denver Earth Science Project’s “Paleontology and Dinosaurs” module written for students in grades. Extinction of species is common; most of the species that have lived on the earth sir longer exist.
The complete “Paleontology and Dinosaurs” module takes approximately four weeks to teach. The “Who’s On First? Scientific measurements such as radiometric dating use the natural radioactivity of certain elements answer in rocks to help determine their age. Scientists also use direct evidence from observations key the rock layers themselves to help determine the relative age of rock layers. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed.
Interpreting the Fossil Record. Paleoanthropology is the study of early forms of humans and their primate ancestors. It is similar to paleontology except its focus is documenting and understanding human biological and cultural evolution. Paleoanthropologists do not look for dinosaurs and other early creatures. However, like paleontology, the data for paleoanthropology is found mainly in the fossil record. Before examining this evidence, it is necessary to first learn what fossils are and how they are formed.
Line of Evidence – Fossil Knowledge & Dating Activity. The rock strata are in order from oldest, at the bottom, to youngest, at the top, and all of the layers have a.
Fossil record , history of life as documented by fossils , the remains or imprints of organisms from earlier geological periods preserved in sedimentary rock. In a few cases the original substance of the hard parts of the organism is preserved, but more often the original components have been replaced by minerals deposited from water seeping through the rock. Occasionally the original material is simply removed while nothing is deposited in its place; in this case, all that remains is a mould of the shape of the plant or animal.
A brief treatment of the fossil record follows. For full treatment, see geochronology. In some places, such as the Grand Canyon in Arizona , it is possible to recognize a great thickness of nearly horizontal strata representing the deposition of sediment on the seafloor over many hundreds of millions of years. It is often observed that each layer in such a sequence contains fossils that are distinct from those of the layers that are above and below it.
