Bite marks preserved in fossil bones can provide rare evidence of how prehistoric animals behaved and interacted within ancient ecosystems. Using both earlier research and their own findings, the team also created a guide for interpreting possible tooth marks on fossils. Separating True Bites From Other DamageIdentifying genuine tooth marks is not always straightforward. Researchers must distinguish between these possibilities before using fossil marks to reconstruct prehistoric behavior or ecological relationships. "The study of tooth marks on fossil bones is important because it provides valuable insights into animal behavior and interactions between species."
