Gianotosaurus, from Arengentina. And while I'll adimit to liking JP III, the whole Spinosaurus thing jaded me to, considering any creature with a sail that big is not going to engage in any activity that might damage it, like fighting or hunting large prey. Which is why, along with it's straight, not curved teeth, led my (non-profeessional) opinion that Spinosaurus was a really big vuluture, using it's size to steal a meal, or a fish-eater. But yeah, walking with dinosaurs rocked.
And walking the prehistoric beasts was cool, to.
Giganotosaurus carolinii (you left out a letter) and
Carcharadontosaurus saharicus and
Saurophaganax maximus were also about the same size. Although saying that they are "bigger" than
T. rex may be a bit silly, considering the sample size we have of these animals. We have many more
T. rex's than any of the others with a grand total of ...six skeletons ever found. For
G. carolinii we have one. And it's incomplete to boot, so how big it really is is largely based on estimates.
For what it's worth, though,
T. rex was quite likely a much more aggressive and powerful hunter than any of the carnosaurian therapods (all of the others; they are relatively closely related as allosaur-like animals) even if they did average a few inches longer and a few pounds heavier. And that's all it is, too, is a few inches and a few pounds. The
T. rex's had much more powerful jaws, forward facing eyes, a much leaner and faster physique, much more aggressive and dangerous prey (in the form of
Triceratops horridus) and apparently a nastier temper (some
T. rex skeletons have extremely nasty scars on the bone itself that can only have been made by the teeth of other
T. rexes, and are partially healed indicating that the wounds were made while they were alive.)
Anyway, I have a terrible tendency to hijack any thread on dinosaurs (or other prehistoric creatures) or ancient history/linguistics/archeology with my overly technical analysis, but as to the original point of the thread, I actually preferred
When Dinosaurs Roamed America. It's not nearly as well written, but the actual dinosaurs look tons better. And let's face it; I don't watch those to learn about dinosaurs, because I already know much more than they're gonna tell me, I watch it to
see dinosaurs. So
When Dinosaurs Roamed America followed by any of the
Jurassic Park movies, and I too liked all three, win out over
Walking With Dinosaurs or
Allosaurus any day of the week and twice on Sunday.
