T.rex Senses

I could see it.

It's possible, but, something probably would have stoped it like climate change or something that seems to stop most of the super predators, I myself think that the raptors would have lasted the longest, because unlike rex they wouldn't need as much food so they could live off other small animals that could also survive a climate change.

I meant among super predators, not the little ones. But, climate change might not have been as much a problem as you think. If Earth got colder, they'd probably go farther south. That, or the ones up north would die out slowly, but the ones further south keep thriving. If the earth got warmer, then opposite of previous situation. 

I think what he meant was T.rex could have been like, say, Allosaurus. Allosaurus was around from roughly 140-155 million years. A 15 million year run without changing much. If I'm correct, MrHappy means T.rex could have done something like that(maybe even longer) before it adapted and changed.

Posted that the same time MrHappy posted his, so ignore that if you wish ;)

That's another way of looking at it though. It's a valid perception. 

True, I don't know there's a reason why all of these super predators go extinct ussualy climate change sometimes there prey disappears or sometimes something better comes along.

I do think T.rex could definitely go for a long run but, if something changed significantly like there main prey dies out, or something better comes along or extreme climate change I just don't think something as large as a rex would survive unless it changed.

Don't get me wrong I completely understand what you guys are saying, I understand that rex was one of if not the most advanced predators to ever live but, I just don't think any super predator is invincible.  

I know what you mean Hipho. No species lasts forever.

Thanks for sharing this information RexFan!

Just feel like pointing out that although rex had a large brain, most of it was purely for interpreting its senses, and its intelligence would be more comparable to that of a crocodile. I'll try to find the study that found this and share it with you guys.

Silver, Tyrannosaurus relative brain size was still within the range of modern reptiles, being at most 2 standard deviations (SDs) above the mean of non-avian reptiles log REQs. The estimates for the ratio of cerebrum mass to brain mass would range from 47.5 to 49.53 percent. According to the study, this is more than the lowest estimates for extant birds (44.6 percent), but still close to the typical ratios of the smallest sexually mature alligators which range from 45.9–47.9 percent. That said, T.rex intelligence is hard to determine without living specimens.

Now that is awesome, great find. :)

Yeah, I'm just saying that I see many people saying that T. rex was really smart, and although for its time it was certainly above average, I find that compared to modern day animals, it is nothing.

Thanks, glad you liked it bigbadben :)

Silver, I agree T.rex was no genius compared to some modern day animals, but for a dinosaur, it was an Einstein. Some birds(the Harris Hawk for example) hunt in family groups and if T.rex was a smart as some birds, then maybe that's more evidence for group behavior in large tyrannosaurs. Kind of random, but you know, that's me.

No problem rex fan. :)

Hey by the way if you don't mind please check your scified inbox. :)

I see the message. I'll go look :)

I always heard Rex had great senses but not this good! Either way I still would not to be near this dinosaur

Agreed Allotitan ;)

In contrast, Acrocanthosaurus had limited depth perception because they hunted large sauropods, which were relatively rare during the time of Tyrannosaurus

Not that persay, but they eyes of the Carcharodontosaurs/ allosaurs were situated more to the sides of their heads, where as in tyrannosaurus they are placed more near the front, giving it binocular vision.

had 13 times the visual acuity of a human, thereby surpassing the visual acuity of an eagle which is only 3.6 times that of a person. This would have allowed Tyrannosaurs to discern objects as far as 6 km away, which is greater than the 1.6 km that a human can see

I honestly don't know how this sort of thing is not common knowledge yet. Of cours Tyrannosaurus had better visual acuity then that of humans or raptorial birds. It's substaintially larger, and much taller then even the largest of both species.

Tyrannosaurus has been virtually the only theropod to undergo such scrutiny. Been passed under the miscroscope more then any other. Why? it's infamous. If they did the same studies with Giganotosaurus, hell even Gigantoraptor...the results would probably be different...but still at that level. Doing studies like this on other dinosaur species could and indeed will shine a whole new light on paleoecology i believe...i look forward to the day these studies are conducted.

Good job with this by the way, you presented it quite nicely.

Nice post Rex Fan.

I agree with everthing but the eye-sight (no offense). I just don't know that you could discern all that optical information with just a fossil. And sure, they have their machines and numbers, but they could be wrong. How would you know that t-rex had binocular vision, let alone better than hawks and eagles, without an actual t-rex eye?
