Possible life on near planets?

I know people are fascinated by the ideas of extra terrestrials and so am I. The universe is so huge I don't think we will ever know how big it really is. With the findings of more then 350 earth like planets is it not possible that one of those planets could have animals such as dinosaurs on it? I know they were wiped out 65 million years ago but could it not be possible they live on other planets? The closest animals related to dinosaurs on our planet are Sharks, Crocodiles, Rhino's & Elephants. Please give me some thoughts on this cheers.
