Dinosaur intelligence

I agree they were smart, but I'm not sure about chimp smart.

Advanced herbivores like hadrosaurs and ceratopsians were probably pretty smart(for herbivores). Maybe as smart as alligators.

Allosaurus and other "average" theropods were probably at least as smart as alligators.

Tyrannosaurs and other advanced theropods were probably as smart as house cats.

Raptors and troodonts were about as smart as lions or wolves.

That's how I break them down at least.

As you two, I consider dinosaurs were pretty smart reptiles.

That's how I put it, entirely based on brain-body size ratio:

Sauropods and Tyrephora: as smart as the dumbest cow;

Ceratopsians and Hadrosaurs: as smart as horses (sorry for being un-original, but I couldnt find any herbivore smarter han a cow, but not too smart);

Ordynary theropods: as smart as alligators/crocodiles;

Raptors: as smart as wolves;

Advanced big theropods: somewhere between.

That's pretty close to what I think. Shocker, haha

Haha, it always amazes me how similar our thinking is! :D

Chimp intelligence? No.

Large theropods where undeniably smart by Dinosaur standards, but I'd say intelligence wise they're comparable to a crocodile or maybe an Emu or Ostritch. 

Smaller Theropods probably could have approached bird level, some basic problem solving, semi-complex communication ect.

Herbivores probably weren't dumb, but I'd say cow level at best.

I'm not trying to "destroy" your idea, but you may be giving them a little too much credit, as much as it pains me to say, they're still primitive animals by modern standards.

You never know. They could have been that smart. For all we know, they could have been smarter than humans, but could only understand each other, so there would be no inter species communication. Resources could have been too heavy for Dromeasaurs, but large theropods couldn't understand what the Dromeasaurs wanted to do, and neither could herbivores. The large theropods could lift the heavy objects, but their arms prevented them from doing anything with it. 

I doubt any of that is possible, but don't underestimate their intelligence.

A lot of you are forgetting that alligators are about as intelligent as dogs...

i agree! i think the smartest were the raptors like Troodons. Rex probably have intelligence as same as modern day nile crocs. but, we all agree the stupidest probably a species of stegosaur, because in a lot of media tell that stegosaurs have brains a size of a wallnut, and rumors having the second brain in their back. but it turn out to be a sugar storage gland. in the human, it like a person having only iq of 29.

I agree with Sinornithosaurus , I think raptors were as smart as chimps, large theropods were probably as smart as macaws, herbivores=horses

Recent research indicates that it's tricky to rank animals by intelligence because so many animals apply their intelligence and adaptations differently.  We need to keep that in mind when discussing dinosaurs.  For example, a big predator like Tyrannosaurus rex would probably be more concerned with finding large quantities of meat to feed itself than it would with forming the complex social bonds we tend to associate with high intelligence.  That said, it's probably better to think about what it meant to be a smart T. rex than how much smarter than T. rex a small pack hunter, such as Troodon, would be.

RaptoRex, I personally don't like to say any animal is stupid. All animals have basic instinct at least and that doesn't make them stupid.

PS- I found these appropriate...
