In the dinosaur times, did the T-Rex actually attack and eat any different types of dinosaurs and were enemies with all of the non T-Rex?

Update:

The land before time movies imply all of that by making the "Sharptooth" the villains

    They caught and ate any species that were smaller than themselves. Not mouse-size species obviously, but anything big enough for them to grab.

    Yeah, they weren't welcome in many dinner parties of the day.  They pretty much crashed the party.

    So you think that T. rex may have eaten ferns and palm trees?  What are you asking?

    At possibly 10 tons, they would be able to eat most things as long as they could catch them. There were a few animals in its habitat it likely did not mess with too often, like adult healthy triceratops, adult healthy ankylosaurs, large ornithischians and supposedly in its southern range it may have ran into a titanosaur species which it most definitely did not play with.

    T. rex cannot run. One scientist worked out the physics and found that its bones would break if it tries to run. T. rex also has arms too short to catch prey. Its jaws are powerful and can crack bones. Therefore it is most likely a scavenger. Its size would allow it to muscle smaller dinosaurs off their kill, sort of like bears muscling wolves from their kill. Wolves hunt in packs, so a half dozen wolves can drive a bear away and reclaim the carcass. It would take a similar group of small meat eating dinosaurs to drive T. rex away but there is virtually no evidence that small theropods formed packs. Yes there was a bunch of small theropods that got buried alive but that is filmsy evidence at best of pack hunting.  T. rex also has the biggest olfactory bulb of any dinosaur, so it is able to smell rotting meat from miles away.  More evidence that it is a scavenger.

    There are 2 dinosaur fossils (one of them is Triceratops) that appear to have been bitten by T. rex, since the healed wounds on their backs match that of the T. rex's jaws in size and shape. The fact that the wounds healed suggest that even when T. rex manages to get a bite on a dinosaur, it does not always result in a successful kill. Such evidence also suggest that even though T. rex is big, it is able to camouflage itself so that a Triceratops can walk by without even realizing that a T. rex is there in hiding.

    Another line of evidence is that T. rex grew slowly at first, until it reaches a certain size, and then its growth accelerated. That means it relies more on its size and weight to get its food than its speed, since larger animals are stronger but slower, but larger animals can muscle other predators off kills. When T. rex reaches a big enough size, it can eat a lot more by muscling most other meat eating dinosaurs off their kills. However, T. rex also show broken bones and healed wounds, suggesting they probably fight among themselves for the possession of a kill.

    It was a large carnivore and preyed on other dinosaurs. It was an opportunistic feeder and would have scavenged carcasses as well as hunted live prey. There is some evidence it would eat other T. rex but we don't know whether it was cannibalistic and would hunt and kill other T. rex or whether it simply opportunistically fed on the carcasses of dead T.rex.

    Depends on how big a dinosaur you are and how big a strike of lightning you were struck with.  

    T-Rex would normally attack, kill and eat any living thing that they could catch including their own kind.  But there favorite food was herbivores.
