is it possible if there are dinosour live in sea???

POSSIBLE?????????????????????

If you think abaut real dinosaurs. No. Dinosaurs where never aquatic. If you think about sea reptiles like Kronosaurus if you think about it we KNOW they are still alive. But the only ones left are Sea Turtles. About other sea reptiles. Maybe. But probably no bigger then 3 meters long.

Also, when aking a question 1 question mark is enough.
