Dinosaurs are pretty unique.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 that stuff from his & mine posts; Crocodiles and Alligators are more closely related to birds than they are other species of reptiles, like lizards or snakes.
Now consider 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.
Yeah my personal opinion is just an overgeneralization. But dinosaurs are indeed unique.

In this thread, I remarked "Modern-day birds like chickens and ostriches would be (distantly) related to theropods like T-rex, and theropods were physically intermediate between birds and modern-day reptiles, but what about sauropods like Brachiosaurus and Argentinosaurus? Whereas say crocodilians and theropods were carnivores with elongated, powerful jaws, sauropods were herbivores that looked more like giraffes and camels." https://wildfact.com/forum/topic-dinosaur-news?pid=114615#pid114615

It's all about classification. Either a dinosaur is a reptile or it isn't. We can't say that some are and some are not. Personally, I believe that Dinosauria should be considered as its own class such as amphibians, reptiles, dinosauria, pterosauria, mammals, etc.

The first discovered bird-like dinosaur (not the first bird-like dinosaur in existence), Archaeopteryx, had feathers and a bird-like beak, but what about its skin? Did it have softer and moist skin like that of modern birds, or did it have rough and scaly skin like that of dinosaurs?
I`m agreed with this one! Archaeopteryx are the earliest-known bird from 150-million-year-old rocks in Germany. This creature, dinosaur-like in many ways, but with fully-fledged, birdlike wings, would have been capable of flight of some sort.
