EARTH: Owl Pellets Bridge Ancient and Modern Ecosystems
FOR IMMEDIATE RELEASE

Alexandria, VA - In a Utah cave, paleontologists are exploring the fossil record preserved in owl pellets since the Pleistocene glaciation. The fossils in the pellets are giving the scientists a glimpse of how the ecosystems have changed over time both from natural variation and more recent changes brought on by human settlement.
By studying the pellets, scientists have been able to assess the energy flow through the ecosystem, and how the addition of non-native plants such as cheatgrass is recorded in the geologic record.
