I’m confident that T- Rex was an opportunist that wouldn’t pass up a free meal. A 14,000 lb lizard is going to be a perpetually hungry beast after all. I’m equally sure he was perfectly capable of running down and killing smaller dinosaurs and eating them. I’m also confident that there are many explanations for a tooth found lodged in another dinosaurs tail but the most reasonable one is that the T-Rex cased own, attacked, and then failed to secure his meal-as is common in the world of predator and prey today.
Without starting a fight, it just seems that you have great faith, not facts nor observation. Who says either was eating anything. Maybe they were just playing, like puppies, and (his, her?) tooth fell out in the fracas.
Let me ask you:
Do T. Rex dinosaur fossils hsve teeth or bones in their fossilized digestive tracts? Or is TR just hypothetically, and universally assumed, to be a carnivore? Or is it just unproven smoke and mirrors?
My suggestion: In God we trust; everybody else please bring data.
If dinosaurs are cold blooded then they would eat very often. Or move very much for that matter.
