Fossils and Ecosystems of La Brea

The La Brea Tar Pits are rich in fossils, including direwolves and saber-tooth cats. Excavators collect dirt around fossils for detailed analysis. The tar pits preserve original bone material due to asphalt seepage. Continued excavation helps build a detailed picture of past life and species changes over time. The museum's collection aids in understanding species evolution, like direwolves shrinking over time. Micro fossils provide insights into climate change effects post-Ice Age, making ongoing research crucial.
