ANTA01H3 Lecture Notes - Lecture 4: Midden, Principle Of Faunal Succession, Absolute Dating
Document Summary
Dating methods: relative dating provides relative ordering of material or sites. Structured by stratigraphy study of the sequential layering of deposits. Principle of superpositioning in a stratigraphic sequence, the lower layers were deposited before the upper layers. Humans can disrupt the layers with burials. Stratigraphic column show the relative positions of layers in locality. After the stratigraphic column, we are linking og geological layers (strata) based on their physical characteristics; called physical correlation. The law of faunal succession strata that contain fossils of the same animals are the same age. Makes use o index fossils (fossils remains of known age) Should be broadly distributed with species of short duration. Winner of the nobel prize in 1960. Carbon: all things are made of atom that have a nucleus with protons and neutrons; 7 protons (atom of nitrogen) Isotopes atoms that have the same number of protons but different number of neutrons.
