How did dinosaurs reproduce?

Dinosaurs reproduced just like all other animals do, I mean, certainly that we know a lot from crocodiles we know a lot from birds but we also, we found a lot of dinosaur nests, I mean as far as we can tell is that is all dinosaurs, non-bird dinosaurs, laid eggs. In some cases we know that, that the animals brooded their nests, just like modern birds do. We found a couple of remarkable discoveries that animals, sitting on top of their nests, you know brooding their clutches, you know, just like the chickens do on a farm today, so that at least in some forms there probably was a great deal of parental care as well.
