Abstract
Rothschild (2014) argues that many tyrannosaurid tooth marks left on isolated dinosaur bones cannot be attributable to their feeding behavior but instead, can be attributable to their play behavior. However, the evidence suggested by Rothschild (2014) are very weak. Carnivores do consume parts like pes, which claimed to be not attractive to carnivores. Also, isolated bones do not suggest that the part was already isolated when the animal bit it and carnivores do not always consume bones even if they have the ability to do so. This suggests that tyrannosaurid bite marks on isolated bones, do represent feeding behavior.
