Quality Considerations for Bone Samples
Bones and teeth are relatively common within the archaeological and paleontological record due to the tendency for high preservation after burial.

Best Practices When Selecting Bone Samples
Bones and teeth can be used for a variety of different isotopic analyses, including Oxygen, Strontium, Lead, Neodymium, Carbon, Nitrogen and dating (radiocarbon and in some cases Uranium-Thorium). There are important requirements for bone samples to ensure they produce accurate results.
Cave Deposits: Chronology Development & Environmental Reconstruction
Caves are natural intact cavities found in many different landscapes which have been accessible to humans and animals for millions of years.
Archaeological investigations of caves
Caves – or rock shelters – have been studied by archaeologists for the past two centuries, with specific focus on the investigation of prehistoric cave paintings, ceremonial use and other evidence of occupation.
Isotopes & Dating in Marine Environments
There are numerous different options for dating marine samples, each with applicable timespans, levels of certainty and limitations.

U-Th Dating in Archaeology
Uranium-Thorium (U-Th) dating is a radioactive method to date a variety of carbonate samples, including corals, cave deposits, cave artwork, shells, foraminifera and bone.
