New study suggests dinosaur bone marks have multiple origins beyond bites

Marks on fossilized dinosaur bones may not always be bite marks, a new study reveals. Researchers found that marks can result from various pre-mortem natural causes or postmortem alterations, not just predation. This distinction is crucial for understanding dinosaur behavior and interactions. The study analyzed over 3,000 bones, with less than 0.4% showing clear bite marks, likely from Tyrannosaurus rex. Other marks may have different origins, requiring careful analysis.
