background image Dating ​ ​Sites​ ​and​ ​Artifacts:   (Reading: ​ ​Ch.​ ​4​ ​In​ ​Textbook)  Relative ​ ​Dating​​ ​-​ ​what​ ​archaeologists​ ​use​ ​to​ ​find​ ​out​ ​how​ ​old​ ​artifacts  are. ​ ​There​ ​are​ ​four​ ​main​ ​techniques​ ​used​ ​for​ ​relative​ ​dating:  1. ​ ​​Stratigraphy​ ​and​ ​Association​​ ​-​ ​the​ ​idea​ ​that​ ​items​ ​on​ ​the  bottom ​ ​are​ ​older​ ​than​ ​the​ ​items​ ​above​ ​them.   2. ​ ​​Typological​ ​Sequences​ ​​-​ ​artifacts​ ​are​ ​organized​ ​into​ ​types  (groups) ​ ​based​ ​on​ ​their​ ​physical​ ​attributes.  Evolution ​​ ​must​ ​be​ ​considered​ ​during​ ​this​ ​process​ ​because  if ​ ​objects​ ​evolve,​ ​they​ ​may​ ​be​ ​the​ ​same​ ​object,​ ​just​ ​with  different ​ ​physical​ ​characteristics.  Inventions ​ ​are​ ​often​ ​a​ ​cause​ ​of​ ​changes​ ​including:  size, ​ ​shape,​ ​decoration,​ ​or​ ​style.   3. ​ ​​Seriation​​ ​-​ ​measures​ ​changes​ ​in​ ​how​ ​common​ ​artifact​ ​types  are ​ ​through​ ​time,​ ​shown​ ​by​ ​seriation​ ​charts.   Seriation ​ ​can​ ​help​ ​us​ ​to​ ​understand​ ​the​ ​culture​ ​that​ ​the  artifacts ​ ​came​ ​from,​ ​and​ ​in​ ​some​ ​cases,​ ​their​ ​religion.  (Example: ​ ​gravestones).   ***Seriation ​ ​was​ ​the​​ ​method​ ​used​ ​before​​ ​radiocarbon  dating.    4. ​ ​​Environmental​ ​Sequences​​ ​-​ ​reveals​ ​regional​ ​and​ ​global  sequences ​ ​of​ ​climate​ ​changes.   Includes ​ ​early​ ​periods​ ​of​ ​human​ ​evolution:  Pliocene ​ ​epoch  Pleistocene ​ ​epoch  Holocene ​ ​epoch  Environmental ​ ​sequences​ ​are​ ​documented​ ​through  microorganisms ​ ​called​ ​​foraminifera.   Foraminifera ​ ​produce​ ​small,​ ​calcium​ ​carbonate  shells, ​ ​which​ ​they​ ​leave​ ​behind​ ​when​ ​they​ ​shed​ ​them  or ​ ​die.  
background image Absolute ​ ​Dating​​ ​-​ ​this​ ​is​ ​when​ ​you​ ​get​ ​an​ ​​exact​​ ​number,​ ​and​ ​where  most ​ ​of​ ​the​ ​methods​ ​used​ ​are​ ​based​ ​on​ ​radioactive​ ​decay.   Half-life ​​ ​-​ ​the​ ​time​ ​for​ ​half​ ​of​ ​the​ ​radioactivity​ ​to​ ​emit.  Radiocarbon ​ ​Dating​:  Carbon ​ ​14​ ​has​ ​a​ ​half-life​ ​of​ ​5,730​ ​years.   All ​ ​living​ ​organisms​ ​take​ ​up​ ​C14​ ​through​ ​the​ ​carbon  cycle.    Radiocarbon ​ ​dating​ ​can​ ​date​ ​​organic​​ ​materials​ ​from  400-500,000 ​ ​years​ ​ago.   It ​ ​is​ ​important​ ​that​ ​you​ ​​do​ ​not​ ​touch​​ ​the​ ​material​ ​before  sending ​ ​it​ ​off​ ​to​ ​be​ ​tested.   When ​ ​you​ ​receive​ ​the​ ​results,​ ​you​ ​always​ ​get​ ​two  dates:   1. ​ ​Raw​ ​date  2. ​ ​​Calibrated​ ​date​​ ​(this​ ​is​ ​the​ ​date​ ​you​ ​really  want)   A ​ ​​negative​​ ​side​ ​to​ ​radiocarbon​ ​dating​ ​is​ ​that​ ​in​ ​order​ ​to​ ​be  tested, ​ ​the​ ​material​ ​must​ ​be​ ​destroyed.   Potassium-argon ​ ​Dating​:  Potassium ​ ​40​ ​has​ ​a​ ​half-life​ ​of​ ​1.25​ ​billion​ ​years.  Molten ​ ​lava​ ​releases​ ​K40​ ​and​ ​captures​ ​it​ ​when​ ​hardened,  which ​ ​as​ ​it​ ​decays,​ ​creates​ ​Ar40.   The ​ ​​ratio​​ ​of​ ​these​ ​two​ ​elements​ ​provides​ ​the​ ​absolute  date.    East ​ ​African​ ​Rift​ ​Valley:  Was ​ ​a​ ​volcanic​ ​deposit​ ​with​ ​fossils​ ​everywhere.   The ​ ​fossils​ ​were​ ​well-preserved​ ​and​ ​could​ ​be​ ​dated  easily.    Dendrochronology:   Tree-ring ​ ​dating​​ ​-​ ​is​ ​based​ ​on​ ​growth​ ​rings​ ​that​ ​naturally  occur ​ ​in​ ​trees,​ ​that​ ​reflect​ ​climate​ ​conditions.  This ​ ​is​ ​able​ ​to​ ​be​ ​told​ ​through​ ​how​ ​thick​ ​the​ ​​spaces  between ​ ​the​ ​rings​​ ​are​ ​and​ ​how​ ​thick​ ​​the​ ​rings
