Age and Correlation of Key Fossil Sites in Porcupine Cave

Show Summary Details


This chapter assesses how key deposits in the cave (Pit, DMNH Velvet Room excavation, CM Velvet Room excavation, Badger Room) relate temporally to each other, to some other localities in the cave, and to the chronologic time scale. It describes the application of acid racemization for relative age placements of Porcupine Cave localities, and assesses the application of magnetostratigraphic, biochronologic, and biostratigraphic techniques to key fossil sites in Porcupine Cave.

Keywords: Pit; Velvet Room excavation; Badger Room; acid racemization; Porcupine Cave; magnetostratigraphic technique; biochronologic technique; biostratigraphic technique
