Avatar - Jurassic Comparissons

[Advent]

Here's something to think of: was Cameron right?
I mean, when he said the Thanator could eat the Queen Alien and the Tyrannosaurus Rex for dinner and desert respectively?

Also, how would the other Pandorans fare against the creatures of Earth's prime? Well? Badly? And of course, we can discuss the equivalents of each biosphere, and similarities or differences to each other.
For example, the trees of the Jurassic era seem rather familiar, no?


Note: this ain't a debate or flame thread. It's a discussion, both for knowledge, and some enjoyment.


..and I'm just putting it out here, but the Thanator couldn't eat the Queen Alien. Acidic blood.
