why do we still call dinosaurs primitive

why do we still call dinosaurs primitive?

because they were long extinct before our existance?

if we were one day to go extinct, and the world was then dominated by intelligent roaches 65 million years later, is it fair for them to call us primitive?

dinosaurs might have been one of the most if not the most advanced vertebrates ever produced. no land animal before or since has ever gotten that large, and diverse.

no land animal before or since has the growth rate of the dinosaurs.

it's physiology must have been impressive. yet we still call them primitive reptiles while turtles, crocs, tuatuas, lizards, amphibians, and even some mammals are more primitive than dinosaurs. what gives?

they were here and were the most advanced for hundreds of millions of years till they were wiped out. all that is left are the birds. we mammals just had our second real spurt in evolution after the dinosaur died out, and we are barely trying to catch their rein record.

we need to re-think what it means to be primitive.

why do we still call dinosaurs primitive

Because they WERE primitive. They didn't understand concepts. Eat. Reproduce. Survive. That's is what dinosurs thought. Yes, they are one of the most diverse species, but that does not have to do with primitive.

No, your idea of "primitive" is wrong.

WE don't know what they did. We KNOW what they ate. THEY have concepts. Since they don't live, WE do not know how they're brain works. THEY could've been smarter than us. WE give ourselves to much credit for inventing things, when Dinosaurs could've done it long before us. I'm not saying like all this advanced technology. I mean long ago, when they were all Neandethal's and stuff. Dinosaurs could've had the same thing, but it was destroyed along with them.

dinosaurs were not primitive. they were the most advanced biomechanically. sure we are smarter, but i doubt our biomechanics or even most mammal's can function more efficiently than dinosaurs and birds.. and birds now starting being considered as modern avian therapods.

the dinos finished the race first.. the mammals are barely starting it. to say that they are primitive cus they lived long ago and died long ago is wrong. why can't an organism be advanced millions of years ago? they were advanced long before we ever became into existance.

Exactly. Why?

THEY have concepts.

No they don't They lack the parts of the brain that can recognize and process concepts...

THEY could've been smarter than us.

Sadly, impossible.

dinosaurs were not primitive. they were the most advanced biomechanically.

We call them primitive because of what I said above...they are not as intelluctually advanced. now lets look at biomechanics.

Humans have a 4 chambered heart, dinosaurs had a 3 chambered heart.

1 for Humans

Humans had opposable thumbs, dinosuars did not..

2 for humans.

Dinosaurs had a more developed Temporal, Parietal, and Olfactory lobe. Humans don't.

1 for Dinos

Humans have a much larger frontal lobe.

1 for Humans

Size does not matter, so does teeth and claws, as those are specialized.

the dinos finished the race first.. the mammals are barely starting it.

So?

to say that they are primitive cus they lived long ago and died long ago is wrong

Yes, that is wrong, but its NOT wrong to say that because humans are more developed than dinosaurs.

why can't an organism be advanced millions of years ago?

They can... but the organism would still have to be living today...like a croc. Crocs are advanced in the way that they are the only "reptile" with a 4 chambered heart...actually, crocs are very close to birds.

If yoiu know abou evolution...the later time goes on, he more advanced the animals get. So in 2 million years, the animals then will see us as primitive compared to them...and I don't have any problem with that!

not true..

no lizard, snake, croc, turtle, ceolocanth, tuatua, snail, squid, or any animal that started before dinosaurs and are still alive today are as advanced biomechanically as the dinosaurs

So? No snail, lizard, fish alive now in not as advanced as us...They all don't have to be the same...

Bottom line is...Dinosaurs are not as advanced as humans...therefore, they are referred to as primitive.

any velociraptor can out perform a human being physically today.

they are just more advanced than us mammals.

they have a physiology similar if not the same as birds.... and birds use and metabolize oxygem more efficently than mammals.

No, we have the same. Velociraptors are no like birds in he first place. The have a 3 CHAMBERED HEART...which means they are cold-blooded and don't utilize oxygen and energy as effecien as mammals and birds.

Exactly Burnside!

actually velociraptors are believed to have a 4 chambered heart. and have non flight feathers which insulates their body.. hollow bones with air sac chambers like birds today.

even the duck billed dinosaurs have a 4 chambered heart and they are not as closely related to birds as velociraptors. they did a CT scan on a hardrosaur mummy called "leonardo" and found it to have a 4 chambered heart.

The heart cavity left by the fossil indicates a small 3 chambered heart.

I never knew leonardo underwent a CT scan...link please. I could not find it.

I agree with cyrus. I don't know anything about the fossilized heart cavity (source?) but I do know that there is evidence that they had may have had a diaphram like mammals. Besides, the skeletal structure of alot of dinosars indicate that they must have been quite active. Compare their skeletons to any reptile today. All reptiles have a low-slung sprawling posture. Far from anything like velociraptor and any dinosaur like it. Infact, I don't even consider dinosaurs to be reptiles.

Just because they died out does not mean that they were any more primitive than most animals alive today.

That's a really good point.

Just because fish breathe water deosn;t mean they're more evolved than us.

Plus the world has changed so much in 65 million years that it's crazy for us to say their primitive when their not even comparable to our time now

Good point about the low-slung skeletons; Most ancient crocodilians had straight-up legs, if I'm not mistaken. I wonder then if the sauropod hip structure more closely represents the reptile structure of today? Tell me if I'm way off, frogfish, I was into all this stuff when I was small and I don't remember it much anymore. :lol:

I don't agree with that. I've seen many people outrun a dog. Including myself.

Almost all animals have diaphrams...its what lets us breathe!

But they are primitve to humans.

Yes, but this doesn't matter. They are more primitve to humans.

Ok, fine, cheetah.

Primitive isn't a bad thing. It doesn't mean their stupid.

It just implies a simplistic form, actually more defined and to the point.

If I'm not mistaken reptiles don't have a wall of muscle between the lungs and stomach. Instead, the lungs are pulled by muscles attached to the ribs.

Yes, but this doesn't matter. They are more primitve to humans.

I'm not arguing you about that. I'm just saying that their posture makes them quite different from any cold blooded animal existing today.

Perhaps those prehistoric crocodilians were warmblooded? Why aren't modern crocidillians warmblooded? Rather than decending from them, maybe they instead only shared a common ancestor. Curiously the ancestors of mammals were sprawling creatures. But maybe warmloodedness in mammals evolved later.

Same function as a diaphram

I agree...so? What does that have to do with them being primiive compared to humans?

No, as modern crocs are parctically the same as prehistoric crocs.

But maybe warmloodedness in mammals evolved later.

They evolved as the heart evolved.

Duh, they were a differnt kind of reptile. Remeber, snakes, tuataras, lizards, and turtles/tortoise lived alongside the dinos.

Correct. But a diaphram divides the body cavity. Reptiles' lungs are concroled by muscles between the lungs and the ribs. A diaphram is more efficient.

Nothing. You said dinosaurs were cold blooded. I'm merely trying to point out were more advanced than any reptiles living today.

Duh, they were a differnt kind of reptile. Remeber, snakes, tuataras, lizards, and turtles/tortoise lived alongside the dinos.

But for me, it leans toward the fact that dinosaurs were NOT cold blooded.

By the way Frogfish, I'd appreciate it if you didn't talk down to me. I'm not a dumbass, so it isn't necessary. Sure, I may be be going off topic a we bit, I'm just arguing a couple statements you made earlier.

Ok, let me state several facts about dinosaurs against warm-bloodedness.

-Dinosaurs are reptiles, and reptiles are cold-blooded...Therefore, dinosaurs are cold-blooded.

-Many dinosaurs had sails on their body, most likely for thermoregulation. No warm-blooded animal needs this. Osme of these dinos were Spinosaurus, Ournanosaurus, and Amaragasaurus.

-They don't have 4 chambered hearts.

-The number of dinosaurs dropped as Pangea broke apart and drifted more north and south. Possibly meaning they could not survive colder temperatures. (Cold-blooded)

Plus, your point that they are more advanced over modern reptiles is off-topic. This is about humans and dinos.

Actually no. The debate is if they should be considered primitive. Those facts you stated sound old fashioned to me. You are making them out to be way more primitive than they actually were.

From what I have read, the fossilized heart was four chambered with a single aorta like birds and mammals.

My sources:

Here

And here

Ooooo! And looky here

Where is your source Frogfish?

Some dinosaurs had feathers. What is the point of insulation if an animal is coldblooded? As for the sails, it is likely that they were used for display.
