First, the babies hatch and yet have no food except each other but yet grow to adults in large numbers. Second the volcano has been dormant for a few million years plus and yet it is called Mt. Arat which has been explored many many times but yet never were found any of the eggs, the nests, or bones of any of the adults that laid the eggs.... Then we have a group of college kids none of which would have been taken on any kind of expedition with as limited amount of supplies they had. The we have a rip off from "Starship Troopers" with the cutting in half of some and decapitating of others with there wings. For one their bones are hollow and the impact on the the human body would have snapped them like matchsticks. Then we have them over and over crossing OPEN land when they the experts on the Pterasaurs and a covert SPec Ops unit that would always stick to the cover of the trees, being attacked over and over, DUH. Then comes their flying Pterasaurs were gliders, they would have had very limited fling abilities, let alone able to hoover, fly backwards etc. Then we have T-Rex hatching in the same area as the Pterasaurs, No animal will make its nest with in snacking distance of another predatory species. And again we have more eggs and babies with nothing to eat but each other, let alone learn from. Plus T-Rex was not a social animal and yet it looks like a few mothers laid their eggs in the same area as at least 30-100 eggs were implied. Take out the science, lack of basic sense, a lack of real military actions, then it might be worth it as a time killer, if you are desperate.
