Where were the bite marks found on the skeleton?

Alamosaurus bones with T.rex bite marks have been found. Whether this indicates predation or scavenging, we don't know.

I agree with Rex Fan, all Non-Avian theropods had a good sense of smell, but Tyrannosaurs had the best.

And there is no fossil evidence suggesting that T. Rex preyed on them (Sauropods did get big to avoid predators after all). But imagin a Triceratops charging a straight at a T. Rex with Monocular vision, the T. Rex would not even see him coming! I would actually feel a little bit bad for the T. Rex.

It seems all theropods had a good sense of smell(T.rex having the best), so yes, allosaurs had a good sense of smell.

Correct. Many sauropod hunters had somewhat poor vision. And yes, T.rex territory only overlapped with that of Alamosaurus in the south, but they did encounter each other once and a while.

That actually makes a lot of sense, because most other large theropods (Carcharodontosaurus, Giganotosaurus) had large sauropods living alongside it. Plus I read something that said that Alamosaurus was only really in the Southern United States and Mexico, meaning Tyrannosaurus did not encounter it in all of its range.

Yeah, kinda like that. A limited overlapping field of vision. It's vision was good enough for hunting, that's for sure. Tarbosaurus and Zhuchengtyrannus hunted more sauropods than T.rex probably did(though it did hunt Alamosaurus from time to time) and binocular vision wasn't quite as important for hunting huge sauropods. It was more important for hunting ceratopsians and hadrosaurs, which Tyrannosaurus did more often than the other two.

Yes.

Thanks Mr. Happy! I'm glad there was at least some you have not heard of.

I meant they had at least some binocular vision.

Nice list. The the general population most likely hasn't heard any of these. However, I've heard of all but Beishanlong and Rapator. Interesting creatures they all are though. 

Oh I see, so it sort of had a combination of Binocular vision and Monocular vision.

And TK, not all tyrannosaurs had it. Tarbosaurus and Albertosaurus for example. Their vision was kind of limited. Better than earlier carnivores like Allosaurus, but not fully binocular either.

Hard to say for sure since a full skull isn't known. However, it seems Tarbosaurus was it's closest relative. If Zhuchengtyrannus had binocular vision, it was pretty limited.

And yes all tyrranosurs did though t.rex had the best. Zuncheng had a lesser vision because they were more placed on the side then forward as in t.rex. it provably ressembled tarbosaurus in terms of skull shape/size. Any more questions just PM me.

Yeah Zhuchengtyrannus is pretty cool. You being a Tyrannosaur expert, I actually have a question to ask about Zhuchengtyrannus. Did Zhuchengtyrannus have binocular vision like Tyrannosaurus? I know Tarbosaurus didn't, so thats why im asking that.

Same, I loved Dinos since I could first talk. My first movie was walking with the dinosaurs. And I am sure you love z- rex because it is the closest to t.rex.

I can see that, yes, lol. Of this list, "Z-Rex" is my favorite...

Lets just admit it, anydody who didn't want to be a paleontologist at that age probably did not have a normal childhood.

Personally, I've heard of all of these. But then again, I've been studying dinosaurs since age 2(ok, so not really studying then, but still).

Let me guess, you've heard of Oxalaia, Epanterias, Zhuchengtyrannus, and Siats. Anyways, thanks!

ive only heard of about 4 of these. this is a cool and interesting list

I know when they first found it they classified it as a species of Megalosaurus, which is a close relative of Torvosaurus. Although I think the only Megalosaurs (Torvosaurs) that survived into the cretaceous were the Spinosaurs, except for some possible fossils of Afrovenator and that one theropod from New Zealand. But it is possible that it might have been a Megalosaur, especially because Megalosaurs were abundant in Europe during the Jurassic period.

This is a good list, I never heard of Rapator and Beishanlong before!

I heard that Becklespinax was actually a new genus of torvosaur, but I consider the source unreliable b/c I don't have the link, nor do I remember the website.  Would anyone here think that there is some validity in that hypothesis?

I can understand that, after all a lot of these theropods have not been studied very well (that is sort of why they are on this list). I just looked at a lot of their closest relatives and went off of that, although that is definitely not the best way to get their sizes.

I do find some of these sizes to be a tad high(the 9 ton Oxalaia for example), but the species chosen are good :)

Thanks guys, I would add pictures, put my computer can't add them to posts for some reason.

I like the list even though I already herd of all of these. And it's all right to not have pictures I never have any and hey people like my threads, I hope. Btw I have a series that is only about top 10s list.

Good list. I'd add pics myself, but that's just me. I got a thing for top 10s, so I always appreciate a good one.

@ Lord of spino,I haven't seen many crocs.

Nice video Dinosteve, though the lions had an advantage in numbers, im sure much larger crocs battled theropods in a similar manner.

BTW Tyrant King, I know gators are a common sight there, i bet its interesting living there. Have you seen any crocodiles though? I know that Florida has a species of crocodile called the American Crocodile, but I think there only in southern Florida.

Rex fan, the tail of a modern day croc or gator is enough to crack your leg or chin. So saxrosuchus or deinosuchus, and prurrasaurus would completely destroy you. And I don't think they would be able to gallop for a long time.

lord of the spinosaurus, I live in the great and hot state of Florida so gators are a common sight and I know what they can do. Flatten stout skull, break your neck, and ruin your day:)

What an interesting topic. I think those fights (or not even that, maybe show-offs, I think none of them would bbe stupid enough to keep fighting) can be comparable with modern Lions Vs. Crocodiles.

Sounds awesome.

I remember I saw that episode when Paul got bit, it was not the alligators fault, it was Paul's fault and he admitted it. But yeah, going there was pretty cool. I also went on an airboat tour, we saw a couple of wild alligators, one of them even tryed to sneak up on a bird and eat it, but he failed. It was interesting to watch though. I also remember the airboat turning around and I seeing an alligator literally a couple of feet away from me in the water, just looking straight at me, but luckliy it just went underwater and swam away.

And tremendous stress on the person ;)

Glad you enjoyed the post though Alpha :)

I absolutely agree with you Rex Fan, ancient crocodilians would have behaved EXACLTY like the 10.5 foot bull gator in the video.  Crocodilians have hardly changed in appearance at all since the Mesozoic, so who's to say that they would have done something different in terms of behaviour?

Lord of the Spinosaurs, it's so cool you got to see one of their shows live, but I have a real problem with them sticking their heads in the gators' mouths.  Paul did actually get bit once by a 10 foot male, and even though all he got were some puncture wounds that just bled, no broken skull, it coud have been a lot worse.  More still, it puts tremendous stress on the animal.  

I agree with ya Lord of the Spinosaurus. Crocs are very dangerous on land.

PS- It's awesome that you got to see one of their shows live. I've only watched the TV show(which I love, lol).

I have actually been to Florida and seen one of their shows at the the Everglades Holiday National Park. Its insane, they seriously put their heads inside an alligator mouth and they have quick enough reflexes to pull their head out right as the alligator has decided he has had enough.

Anyways on topic, Crocodilians are a lot better on land than we give the credit for. Infact, one species of crocodile, the freshwater crocodile from Australia can even gallop. Crocodilians also have pretty quick reflexes as shown by this video, although they have there weaknesses, like the fact that they have Monocular vision so they cant see directly in front of them, but I doubt any dinosaur would know that. But I'm sure from time to time a Tyrannosaurus would make the mistake of messing with a sunbathing Deinosuchus, or a Carcharodontosaurus would make the mistake of messing with a sunbathing Sarcosuchus.

Anyways thanks for the post Rex Fan 684! It really does make you reconsider.
