I'm not saying it's not possible or not unlikely I'm just saying we can't guarantee it until more evidence shows up, it would definitely have been a coetitor to Carcharadontosaurus and Spinosaurus.

Is it just me or is that when there is a large spinosaur and a Carcharadontosaur theres ussualy a large Abelisaur.

two main examples 

Carcharadotosaurus

Spinosaurus

This theropod

Giganotosaurus 

Oxalia

Ekrixinatosaurus

Wonder which of the three was ussualy the apex predator?

Thyreophora- Kentrosaurus

Ornithhopoda- Orodromeus

Marginocephalia- Torosaurus

Sauropoda- Brontomerus

Theropoda- Torvosaurus

Pterosaurs- Ornithocheirus

Marine- Pliosaurus

Stegosaurus 

Shantungosaurus 

Triceratops

Argentinosaurus 

Giganotosaurus 

don't have one

Dinosuchus (if that doesn't count its Mosasaurus)

very interesting indeed.

@HHP we have a variety of species with considerably less material that we consider large bodied. Amphicoelias, Carcharodontosaurus, the Broome Titanosaur, Oxalaia, Sauroniops...That's to name just a few.

From my understanding, the initial report was this thing was roughly 40% complete. More then enough to get a fair size estimate off of, and seeing that they scaled off of Ekrixinatosaurus, it is indeed massive in stature.

The implications of a gigantic abelisaur are tremendous. Surely, it would have competed with the Carcharodontosaurs and Spinosaurs it coexisted with. Maybe even occupying the same niche, who knows. I for one am excited for the full description of this thing...even if it shrinks

http://www.jurassicworld-movie.com/community/forums/topic/25702 Here's Dinofights topic about it. His sister was the palentologist who found the skeltons.

Thyreophoda-Ankylosaurus

Ornithopoda-Parasaurolophus

Margino-triceratops

Sauropoda-Brachiosaurus

Theropoda-Charcharodontosaurus

Pterosaurus-terodactyl

Marine-Predator-X

i couldn't find anything on this find any where, who was the lead paleontologist? where was it? i mean i wanna see this thing and read it out...no idea where to start though. I read that fight...believe RexFan and some no longer active members wrote it out. Pretty interesting for sure

Yeah I know, if that's what happened that's probably one of the only cases were a predator choked on his meal.

Thats sad he survived the figth but choked in a bone, thats like the WW2 general that died in a car acciden't

Odd angle for a photo but no feathers so far so I'm a reasonably happy bunny

I'm hoping for Mapusaurus! :)

good chapter.

Good chapter as usual, looking forward to the next one. 

Lythronax hopefully. 

Thanks guys! I'm glad the fight came out with positive results!

Who will win next time the earth lizard or the gore king of the south? Find out next week on Survival of the Fittest

Nice fight! I was rooting for Tyrannosaurus, but nonetheless a good fight.

Nice fight Carnosaur! I was rooting for Suchomimus.

This is interesting. Thanks for sharing this!

Interesting topic I hope Titanovenater is as huge as they say

Thanks!

Cool find, until we have more remains I'm still going to consider Ekrixinatosaurus the biggest Abelissaurid.

good chapter utha :)

Glad y'all liked it...missed writing these..

@Mr.Happy yeah haha, my math is pretty terrible and i was exhausted when i wrote this...changed it

Great chapter

Nice fight, was rooting for suchomimus.

Great chapter!

Nice fight, to be honest I'm glad that the under dog won this one!

Thanks Mr. Happy

Nice fight, you know who I was rooting for, but that doesn't matter. Looking forward to the next one.

Rooting for Bitsa but happy with either one. Great fight. 

Call me crazy, but I was rooting for Bista, but expecting Sucho to win. 

For the odds thing, don't you mean 65-35 in Sucho's favour?

Great fight. I was rooting for Suchomimus.

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.

lookin forward to these.

Rooting for...

 Tyrannosaurus Rex

 Mapusaurus

 Megaraptor

 Acrocanthosaurus 

 Sauroniops

 Neovenator

Cat, Alligators in Florida regularly kill burmese pythons in their swamps. But, There have been cases of the opposite happening.

No animal, when put in interspecific or intraspecific conflict, wins 100% point of the time. Unless its something ridiculous(ant vs Ampicoelias, anyone?)

Titanoboa was hyped like no other, it's abilities and natural prowess inflated by the likes of the smithsonian museum and eccentric paleontologists, who's quotes were cherry picked to make it seem like they were saying one thing, when they were in fact saying the exact opposite.

It really didn't look like it was alive, or animate...but i guess it's real

i PM'd it to him, i would do the same guys

Same here, especially since I'm pretty sure I know it.

Nice fight with a believable outcome. Well done and I hope to see more soon.

All three groups were specialized in the prey around them.

The larger tyrannosaurids(Zhucheng, Tarbo, Tyranno) coexisted with ankylosaurs and in the case of rex, Ceratopsians of decent size. Their teeth were adept at crushing for this one purpose, to take them down and make dinner out of them. They occupied one niche, while the Dromaeosaurs of their time hunted hadrosaurs and even the small ceratopsians/sauropods - not to say tyrannosaurs did not do this as well.

Spinosaurs, were obviously adept at catching and killing fish/rays. Not too easy of a feat, as the fish they hunted had the potential of growing to twenty or so feet in some cases. The only competition they really had was crocodilians and pterosaurs, and even the Spinosaurs would have fed on them as well. That niche was theirs for the taking so to speak.

The Carcharodontosaurs, well they are just the Allosaurs but larger...much larger. They kept hunting the sauropods and even some hadrosaurs when they were available. That theropod family is truly the sauropod slayers.

I like how you went around presenting this, as it does seem Carcharodontosaurs/allosaurs were the middle ground if you will between those two 'extremes'.
