Trees as old as time: Using tree resin to reconstruct million-year old ecosystems

Fossil tree resins open a window into the deep past as their organic compounds, termed biomarkers, can be used to identify the botanical provenance of these ancient trees, as well as the paleoenvironmental conditions in which they grew.
