The problem isn't a technical one. The problem is that most if not all of the elements from the story have been stolen and/or bastardized by other franchises and the telling of this story -- much like the original post read -- would come across as a really lame rip-off despite it having come first.
I mean, it would literally come across as a mash of Planet of the Apes and Jurassic Park. Even the original poster crammed them together with his proposal for a T-rex-saves-the-day scenario.
The story is neither popular enough or unique enough anymore to really warrant an accurate or even semi-accurate adaptation. Jurassic Park alone pretty much crushed any hope of a modern-dinosaurs story coming across as anything but a rip-off.
