Did the dinosaurs live?

Know I know what you're thinking "the dinosaurs are dead. They were killed when the asteroid hit the earth." Or "they lived sixty five million years ago. They couldn't possibly still be alive." But I'm not talking about alive today, but millions and millions of year after the impact. I wonder. The birds didn't die out when the meteor hit, and the dinosaurs didn't die instantly, but over another couple years, food ran out and they died. The birds and mammals didn't die out though, and they flourished, so then why didn't the small dinosaurs do the same? The raptors where small enough to go off of lizards, which where still alive, and small mammals too. They where smarter then everything else, and had everything mammals and birds had minus flight and maybe burrows, but I bet the dinosaurs could dig too. Raptors and Troodons are small and fast. They are smart and have the vision of an Halk, with night vision like an owls'. they also had feathers to keep them warm. Over time they could become solitary and smaller, more suited for dwindling food. I bet that they could live at least ten million more years or more after the meteor hit the earth. Assuming they didn't all die out instantly. Or that plauge killed them all. That poses another question, why did the fish survive and not the plesiosaurs or the pliosaurs. Well, I think some of the smaller icthiosaurs and plesiosaurs lived. Ceolacanth lived, and I think the smaller marine reptiles did too. Do they still live today, I don't think so, but it is possible. I may as well state my opinion and say that Megalodon, or at least some giant shark, is alive in our waters. But I don't think that a pterosaur or dinosaur is still alive, and I want you all to know that.
