You don't understand what cold blooded means, do you. They'd have a better chance than you. They know no fear, pain, or happiness. Only bloodlust. You speak of them as if you studied them. Did you join Dr. Grant in Costa Rioca? Seems you don't even know what cold-blooded means in biology. There is no evidence whatsoever about Dino "emotions" How do you know this? There is no evidence whatsoever that land dinosaurs (like Velociraptor) couls swim. Most modern day vertebrated know a basic swim stroke which they use for some minutes to surviove, but the idea that Velociraoptor could swim for large distance, let alone propell a boat, is rediculous. I think you saw a bit too much Jurassic Park, and a little too little fact. And about the book you might write about the case: Michael Crighton beat you to it. As for the topic: assuming "all" kinds od dinosaurs have returned, I'd sit and wait for them to kill off each other the way they did 65M+ years ago. I think the bigger predators would't mind us puny humans, as there are bigger species to feed on. As for their limited intelligence: I think we could outwit/outgun them if it would be necessary. If a T-Rex fell,he died,because his back broke+he wasnt able to get back up(small "arms")
