Earlier life forms?

I think they can do it because pteranodons aren't dinosaurs and they appeared in the movies, and I would love to see other prehistoric creatures in the park.

Well, Seeing how Cloning dinosaurs alone is a HUGE Stretch... I doubt Earlier Life forms would have much DNA Surviving... The dinosaurs didn't have much, And most of them were from the Creatacous (The dilo came from the early Trassic, And because of how little Dilo DNA was recovered, The frog DNA Mutated the few Dilo Strands)

I feel that other Prehistoric species, would wreck the Jurassic Park Franchise...

Man fears Reptilian things, Not warm blooded Mammoths... 

i agree with paden, we might see animals that lived along side the dinosaurs (mosasaurs, pterosaurs, giant prehistoric sharks, etc.) but the Triassic animals, the DNA just isn't there.

Just poitning this out, Dilohposaurus was from the Jurassic period. The Early Jurassic period. It would make alot more sense scientifically for the sceintists of Jurassic Park to have recreated recently extonct mammals and birds. But I dont think the movies were going for realism.

Umm, yes but what then is the deal with those giant dragonflies in the first novel? The common movie goer would not be really capable of making the distinction between dinosaurs and earlier large reptilian life forms, they would just call all of them dinosaurs, same goes for pterosaurs, pliosaurs etc. but yes I respect that it would be a new and maybe not universally popular turn for the franchise, I was just wondering. Thanks for your thoughts on it guys! I still do think some non-dinosaur horrors would be incredible though! Giant amphibians such as Prionosuchus or crocodiles like deinosuchus. I do hope they introduce the larger pterosaurs that existed aswell and do not just focus on the common pteranodon. Regardless, it's looks like the movie is heading in the right direction so it's all good!

It is most likely to have creatures that lived along side the dinosaurs, maybe a few from before. Anything is possible though. What I really want to know is what the scary new dinosaur is going to be. I mean, it can't be replacing Tyrannosaurus Rex since it's on the logo for the movie.

As long as they explain how they did it realistically then I don't see why they can't include creatures from the  late Paleozoic era.

Thank you SOMETHING REAL and yes John Morrison, if it was explained well I think it could be very promising!
