Are Dinosaurs Reptiles ?

That's way too much oversimplification. Not too accurate either. We don't know enough to form much of an opinion (you can't even call birds "fluffy warmblooded dinos" anymore). 

Very often people dont understand the variation within kingdoms well, & the blurred lines between them even less so. 
Many find birds actually being very close to reptiles, close enough to be a branch of it, to be mindblowing & borderline overstated. @Kingtheropod's post is covers just a mere part of the whole spectrum. It's all a very messed jumble.

Feathers are modified scales, and many dinosaurs had feathers. Some didn’t. Look at birds — they have scales on their legs and feet, just like all reptiles. They lay eggs, just like most reptiles. And their teeth, when scientists switch on the gene to grow them, are non-differentiated, just like all reptiles. Lots of dinosaurs had beaks, too. So do turtles.

Consider this; Crocodiles and Alligators are more closely related to birds than they are other species of reptiles, like lizards or snakes.
Now this. There are fish closer related to us humans, than some other fish.

Warm blooded thermo-regulating body isn't any recent development between Synapsids/Therapids (they're NOT dinosaurs, just like they aren't crocodilians or lizards) either. Opah: Warm-Blooded Fish Found. It didn't become prominent in those levels because it wasn't much of an evolutionary advantage among them. Reply
