Final answer:
Coelophysis and Allosaurus exhibit evidence of cannibalism through fossilized bite marks. Understanding these behaviors provides deeper insights into dinosaur lifestyles and their ecological roles. The correct answer is option: Coelophysis & Allosaurus.
Step-by-step explanation:
The two dinosaurs that have been found to engage in cannibalism through fossil evidence are Coelophysis and Allosaurus. Bite marks on the fossilized bones of these dinosaurs suggest that they may have fed on their own kind. This behavior is not uncommon in the animal kingdom and may have been a response to environmental pressures or opportunistic feeding.
Determining the feeding habits of dinosaurs, like whether Tyrannosaurus rex was a carnivore or scavenger, provides insights into their lifestyles and roles in their ecosystems. Another important discovery related to dinosaur feeding habits is the finding of a Triceratops maxilla with bite marks in the Hell Creek Formation, which helps to understand predator-prey interactions during that era.
