Palynology is the branch of science dealing with microscopic, decay-resistant remains of certain plants and animals. It has many applications including archaeological palynology, Quarternary palynology, and stratigraphic palynology.

Marine sediment samples collected with a multicorer

Foraminifera (forams for short). Forams provide two main types of information : ocean temperature of species, O18/O16 ratio (glacial ice volume)

Ocean Floor Cores

Biological Evidence: Tree Rings

Bristlecone pine of the Great Basin region of western North America are the oldest known living trees, up to 5,000 years old.
