Paleoecology
1 reportResearch on Paleoecology investigates ancient organisms or environments through fossils, geology, dating, and evolutionary comparison. Current understanding relies on stable isotopes, food webs, and primary observations, with uncertainty tracked across measurement, classification, and reconstruction.
Questions about how ancient ecosystems are reconstructed are tested against comparative measurements and model results. A second focus is which proxies indicate climate, showing how sparse measurements or incomplete records limit certainty.

Resharpened Clovis Points Track Early Adaptation in Tennessee
An analysis of 489 Clovis and Cumberland projectile points from the Tennessee River Valley shows how early hunter-gatherers changed their use of stone as they learned the landscape
