Document Summary
Know various traits that all primates have in common and which types of primates for the midterm exam. Final exam wed 14th 9am that won"t change. Taphonomic processes involved in fossil formation (last class) We need to remember that our fossil knowledge of early primates is very limited, mostly because: fossilization is an incredibly rare process and our ability to effectively survey and excavate these fossils is limited. K-ar dating is used to date potassium-rich volcanic rock and ash. Because of potassium-40 long half-life (1. 3b years) the upper age limit od k- Argon-argon dating (considered a more reliable technique as it requires only one sample for testing and is testing only one variety of element) Thermo luminescence dating: measures the light emitted by electrons that is captured in the lattice structure of some crystalline elements (they electrons become trapped due to background radiation)
