Top 10 largest theropods

I've done one of these in the past, but it's time for a revision regarding new material that has come to light recently

So, without further adue, let us begin..

10. Torvosaurus Gurneyi

The newest species of megalosaur to date, Torvosaurus Gurneyi is indeed a monster. Though not the twelve meter, 6-7 ton animal it was thought to be based on a 160 cm maxilla, T. gurneyi is still an immense animal. Tipping the scales at 3.5 tons at average and a staggering 5 tons as a maximum, Torvosaurus has earned its place on this list

9. Allosaurus Amplexus

A giant species of Allosaur that was discovered in the 90's, this animal is commonly known as "Epanterias" amplexus. Most paleontologists consider this a nomen dubium, as it appears to just be a rather large species of Allosaurus. Just how big? well, scaling off of "Big Al"(Allosaurus Fragilis) yields ~14meters, 7 tons. But, this figure is a bit baseless and a more safe size estimation should be based off of the DINO allosaurids.. The only size figures given (apparently Stovall´s estimates) published anywhere are found below:
lenght of 42ft (=12.80m), 6.25 tons(6.25 tonnes), height of 16ft (=4.88m in kangaroo pose) a gape of 4ft (1.22m) six inch (=15.2cm) teeth and eleven inch (27.8cm) foreclaws. By comparison Allosaurus was stated to reach only up to 29ft; 2 tons in weight

8. Acrocanthosaurus Atokensis

Slightly smaller then its later gigantic relatives, Acrocanthosaurus is still not an animal you'd want to meet in a dark alley. The largest individual, affectionately known as "fran" was an 11 meter, 6.65 ton beast. Slightly smaller individuals have been unearthed, though they are known fromless complete remains. Estimates for these two range from 10.5-11 meters TBL; 4-6 tons

7.  Therizinosaurus Cheloniformis

The only plant eating theropod on this list, Therizinosaurus is a massive animal. Quite capable of self defense as well, sporting claws that could measure as much as 6 ft. It's appearance is quite bizarre- almost a potbellied, sluggish creature in overall stature. Perhaps this is due to its immense weight; T. cheoniformis tipped the scales at ~5.5 - 6 tons in TBW. Being so large almost certainly kept it safe from most predators - though the claws surely helped.

6. Tyrannotitan Chubutensis

Is it really a suprise most of this list comprises of Carcharodontosaurs? They were massive creatures, and Tyrannotitan was no exception. In Giganotosauridae - the subfamily that includes Giganotosaurus and MApusaurus; two other large bodied Theropods, Tyrannotitan is estimated to measure 12.5-13 meters in length, and, basing off of close relatives, would weigh in the ball park of 5-7 tons.

5. Carcharodontosaurus Saharicus

Ol' Carcharodontosaurus has been kicked around quite a bit on this list. Old estimates have stated it to be anywhere from 6-20 tons in weight, and well they were right-but in a way they probably didn't expect. Carcharodontosaurus appears to be overall more slender then previously thought, and a good deal longer. An overall TBL of 45-48 feet in length, but a meager 5-7 tons in weight have brought this Carcharodontosaur down slightly on this list, but still up there pretty high.

4. Edmarka Rex

The second megalosaur to enter the Fray, Bakker et al. was impressed with the size of Edmarka, noting that it "would rival T. rex in total length," and viewing this approximate size as "a natural ceiling for dinosaurian meat-eaters." Megalosaurs are very heavily built creatures. one "rivaling Tyrannosaurus in length' would be a very sizeable creature.Scaling up a 9 meter T. Tanneri to ~12 meters yields roughly 6.67 tons in weight - on par with the average Tyrannosaurus individual. It is distinguishable from T. Tanneri from several skeletal differences.

3. Giganotosaurus Carolinii

Giganotosaurus has always been in the top five largest predatory dinosaurs. It too has been kicked around though, and recent studies conducted in this decade have shown us something staggering. The holotype, once hailed as a 13 meter animal, has been shrunk down to 12.4 meters in length - a "Sue" sized animal. The second individua, based on scant skull remains, was said to be ~10% larger then the holotype. That would put it at 13.2 meters in length, with a proposed body weight of 7.5-8 tons. It's no wonder Giganotosaurus is still onc of the largest predators to ever walk our earth.

2. Tyrannosaurus Rex

One of the first large bodied predatory dinosaurs ever discovered, Tyrannosaurus has lways been heralded as the largest to ever walk our earth. However, several discovereies in the last twenty years have shown us something rather different. Have no fear- as you can see T. rex is still high up on this list. The largest individual to date, "Celeste" measured an impressive 13 meters in length, and weighed in at 8.5-9.5 tons in weight."Sue" once regarded the largest, measures 12.2 meters in length and weighs in at 7.4- 8 tons.

1. Spinosaurus Aegyptiacus

WHAT?!!you may be asking yourselves, and as i'm suspecting, i'm gonna have to support the hell out of this one to assure you Spinosaurus is still the largest predatory dinosaur to date. The new reconstruction courtesy of PAul Sereno's new finds suggests a semi quadrupedal gait. So, before i start in let me tell you that this new posture gives more surface area for weight to be distributed on S. Aegyptiacus' body. As for 3 ton estimates thrown around on this site because of the new finds, i submit to you ;BS. That's the weight that Sereno et. al gave for Suchomimus Tenerensis - an 11 meter spinosaur. Simple scaling yields ~ 12 tons for S. Aegyptiacus. A semi quadrupedal stance offers the possibility that Spino could weigh substantially more - not less. in fact, It would weigh 50- 75% more then "Sue". That would yield ~ 10-12 tons, sound familiar? So it is this new reconstruction that cements Spinosaurus as the largest terrestrial predator we have found to date.
