How could pirates reasonably transport dinosaurs in captivity, some of them enormous, across oceans?

Would a squad of soldiers who can shapeshift into T. Rexes be useful in a modern battle?

How would a medieval village protect themselves against dinosaurs?

Large dinosaurs are like elephants. Very strong, but the one thing they can't do is jump. Their massive body weight increases with the cube of their size, meaning that large dinosaurs are at the limit ...

Would using thick glass wall be better than electric fence for my dino theme park?

If dinosaurs had a civilization, how primitive must it have been to leave no trace in the present?

A pack of velociraptors in a modern ecosystem, that would be pretty horrible, right?

What are these dinosaur's competitors? According to Wikipedia, a velociraptor is up to 2m long and 15 kg. A Deinonychus is up to 3.5m long and 75kg. I'm going to assume that those masses are the ...

Would it be possible to mount a working minigun onto the saddle of a tyrannosaurid dinosaur?
