Monsters resurrected covered over dinosaurs as well, it portrayed Acrocanthosaurus alright, but megalania(giant prehistoric lizard) it showed as an oversized landshark, killing everything it came across. The spino episode wasn't too bad; with the exception of the Carcharodontosaurus section( it most likely didn't use the "slapping" offensive it was portrayed as posessing. A lot of inaccuracies regarding size as well. Rugops was more like 18 feet - thirty feet is assuming the holotype was a juvenile, which it probably wasn't. It's teeth were small, it's skull was horrifically weak when dealing with high pressues in the skull or lateral torsion, all which points to a scavenger; i wonder why Jack horner didn't take those points into consideration when thinking Tyrannosaurus was a scavenger?
With that said, Valley of the T. rex was hands down one of the most horrific attempts at a scientific outlook on Tyrannosaurus being a scavenger. For one, no terrestrial carnivore to ever exist on the fact of our little blue planet has scavenged 100% the entirety of its life. An animal designed for that would go extinct within a few generations. Secondly,. the tibula being longer then the fibula = slow runner hypothesis is bogus. Horses have this, and can reach speeds of 35 mph. Thirdly, an animal with an acute sense of smell doesn't mean its a scavenger. Smell is a vital part in hunting, but i guess he glazed over that.
He stated he wanted people to think differently, that the beloved Tyrannosaurus wasn't just a killing maching; and he's right. But, he went at it way to wrong. It's safe to say tyrannosaurus killed its prey, as we have evidence of prey animals escaping the attack(hadrosaur bones show signs of Tyrannosaur teeth, wounds evidently healed over) But, it most certainly wouldn't pass up a carcass when it saw it.
Going back to Monsters Resurrected, Spinosaurus in fact probably could pick up a rugops, but not shake it like it did. That was based on the assumption Spinosaurs killed like crocodiles, mainly because the skull is similar. Tests conducted on Spinosaurus' reconstructed skull show that it's skull would have multiple hairline fractures if it killed like it was portrayed to.
