T-rex was not longer than the three but it was taller. Maybe at the head, but not at the hip... Spinosaurus has an extra 2m on it

Giganotosaurus was not the largest carnivore, spinosaurus was way longer and t-rex was stronger taller and smarter than any of the carnivores on the chart.

Yup, but some modern genera are either... A) MASSIVELY overlumped. Varanus, for example. B) Quite constrained in time, not spaning million of years. and C) Subjective. That's the most important thing to remember, genera are subjective groups. In different groups the custom is different. Seeing his post in the DML, Paul didn't seem like he got the memo. And Monolophosaurus looks nothing like Dilong. Meanwhile, he kept the different Leptoceratopsids as separate, yet all of them are more similar to each other that Giganotosaurus and Carcharodontosaurus (and Mapusaurus, far more similar to Giga, remained separate). Paul failed hard in his lumping. HARD. And that is coming from a lumper prone to exclaim "individual variation". FINALLY, someone who shares my failhard views on Paul's lumping! You should see my (uncompleted) list of failed lumpings a page or two back on this board. By the way, it's me, Achilles. You know, the new guy on JPL. Well, I'n not that new any more. But you know what I mean. Hopefully.

^^ Know what you meant, good to see familiar people! Giganotosaurus was not the largest carnivore, spinosaurus was way longer and t-rex was stronger taller and smarter than any of the carnivores on the chart. Erm, the leg of the largest Tyrannosaurus and the leg of Giganotosaurus have 10 centimeters of diference at most. Strenght, well, Spino is twice as large, stout strenght also matters. And smarts? Yeah, twice the brains. That means it goes from 100 grams to 200 grams. Not that it was a genius; behaviour wouldn't be much different.

apparently besides troodon and the raptors, tyrannosaurus was one of the most intelligent carnivorous dinosaurs.

Like all coelurosaurs tyrannosaurs had larger brains than other non-coelurosaur carnivorous dinosaurs of a similar size (eg. carnosaurs). However they wouldn't exactly have been very 'clever' (in anthropomorphic terms).

apparently besides troodon and the raptors, tyrannosaurus was one of the most intelligent carnivorous dinosaurs. Only because of some random dividing line. Troodon is the smartest because it's the most bird like (and actually, smaller, more primitive troodontids, which are more birdlike than Troodon, seem to have bigger brains). Troodon formosus happens to be the only member of its family that's even been studied that way). Archaeopteryx has a bigger brain than troodontids or Epidexipteryx but it doesn't get included because it's over the imaginary "bird" line. Yanornis is by far the smartest of all Mesozoic dinosaurs...

although tyrannosaurus wouldn't have met a giganotosaurus it would still win the fight.

Honestly, this has been done to death, which is why you haven't actually seen any responses, and probably won't (other than snide or sarcastic ones)--and while I am sure you were serious, the fact is that you cannot claim 'truth' for anything that you cannot test exhaustively. But mostly, don't start overloading the board with a one-person argument. It's kind of disturbing.

Well, lets bring the topic back to the rails. Just a bad cut and paste job made with paint of 2 of Dinoguy's charts, but still, shows how overlooked Allosaurus is, and how it can easily be told apart from Tyrannosaurus, even by silouette alone. Also... upload.wikimedia.org/wikipedia/commons/f/f9/Dromie_scale.pngJP raptors would have to have really odd proportions. upload.wikimedia.org/wikipedia/commons/a/a3/Pachycephalosaurus_scale.pngPachycephalosaurus grew its dome and shrunk its spikes as it grew, even without counting Stygimoloch (lol Dracorex). upload.wikimedia.org/wikipedia/commons/7/7e/Spinosauridscale.pngIrritator's size feels odd. Could it be a juvenile? upload.wikimedia.org/wikipedia/commons/6/62/Morrison_theropods.pngI owe this chart a good mark in an uni exposition. But yeah, fully grown Ceratosaurus is built like a truck, fully grown Allosaurus is a giant theropod, Torvosaurus got overshadowed, and hence went extinct as Allosaurs grew larger.

Allosaurus - overlooked? Really? ;D Thanks for posting the chart and links though.
Regarding the JP raptors - would be fun to paste one on that chart to get an idea of the peculiar proportions.

Well, the guy is used as your average Tyrannosaurus substitute, so its own traits are often disregarded.

"Pachycephalosaurus grew its dome and shrunk its spikes as it grew, even without counting Stygimoloch (lol Dracorex)."
Are we sure the knobs on one just werent more worn down than the knobs on the other? Seems more logical to me than....shrinking. Or maybe one was just better preserved than the other.
Don't get started on the stygi draco thing please.

Draco is a not fully grown specimen of Stygimoloch, and a quick look around the DML will tell you that that is, despite what may seem otherwise, the mainstream view. Stygi being Pachy, well, may be, may not be, but Draco is Stygi just like Nanotyrannus is Tyrannosaurus; ie: Bakker doesn't like things that have his name and a date after their name being sunk into older genera.
The knobs, well, osteological study says they shrunk. Not erosion, but actual histological erosion. Also, logical? They have a freaking dome in the head! Marginocephalians have such odd things that what may seem common sense when talking about anything else has to be taken with a grain of salt.
Many Internet arguments would be avoided if more people read the paper about Pachies and just looked at the data.
