Just some food for thought regarding MUCPv-95 and MCF-PVPH-108.145, the Giganotosaurus and Mapusaurus fragments a lot of you in this thread discounted due to the potential of individual variation: It goes BOTH ways.
So just as MCF-PVPH-108.145 and MUCPv-95 could be the exact same size as more average individuals of their species, MUCPv-95 could be a Giganotosaurus that is more than 8% bigger than MUCPv-Ch1 but with a proportionately slender jaw. Also, MCF-PVPH-108.145 could be a Mapusaurus that's more than 10% bigger than the Giganotosaurus holotype but with just a smaller pubis. Not saying it's guaranteed, but if you're gonna apply individual variation bear in mind it's not a one way street. Also, just thought I'd mention that, on average, Giganotosaurus does indeed seem to be bigger than T rex after all - we have a range of ~4 (Bucky, B-rex, Black Beauty, etc) to ~7.47-8.4 tonnes (Sue, Scotty) for Tyrannosaurus, which gives us an average mass of about 6 tonnes. See this post (link) for more elaboration. Meanwhile, we have ~8.17 tonnes for MUCPv-Ch1, and an estimated ~10.29 tonnes for MUCPv-95 (link), which would give Giganotosaurus a mass advantage of 4+ tonnes at lower sizes and 3.23 tonnes on average - heck, even if we disregard MUCPv-95, you have an animal with almost 2.2 tonnes of mass advantage over the average Tyrannosaurus. At maximum, Giganotosaurus is larger at well, by almost 2.4 tonnes. 
Anything you say regarding Tyrannosaurus should be taken with a grain of salt because you have a reputation of constantly downplaying the animal as much as possible. You do it all over the discord and all over WOA then state you do it because of fan boys. You really need to stop hiding behind that because we can all see through it. As was said in the discord regarding what you have stated here.
Quote:based on the very limited data we have I think it is reasonable to say Tyrannosaurus rex and Giganotosaurus were pretty similar in their average adult size, but saying either significantly edges out the other on average is rather premature considering the very small sample size in Giganotosaurus especially 
Warning: therizinosaurus wasn't a carnivore ! but I really don't know how to place him in the dinosaurs' classification. It's stated that he stemmed from a carnivorous ancestor, and become an herbivore, so...
" The first fossil remains of Therizinosaurus were discovered in 1948 by a joint Soviet-Mongolian fossil expedition, in the Nemegt Formation of southwestern Mongolia. The expedition unearthed several giant claws that measured, including presumed horn sheaths, up to a metre in length. These were named and described by the Russian paleontologist Evgeny Maleev in 1954. Further expeditions unearthed more fossils. The first were specimens IGM 100/15-17: several more sets of claws and parts of the forelimbs, described by Rinchen Barsbold in 1976. Another find was specimen IGM 100/45, consisting of hindlimbs, described by Altangerel Perle in 1982. "
I don't want to be cruel with the modern scientific men' ancestors, but here is the evolution of the megalosaurus's depiction through the two last centuries...
" Albertosaurus (meaning “Alberta lizard”) is a genus of tyrannosaurid theropod dinosaurs that lived in western North America during the Late Cretaceous Period, about 70 million years ago. The type species, A. sarcophagus, was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named. Scientists disagree on the content of the genus, with some recognizing Gorgosaurus libratus as a second species.
As a tyrannosaurid, Albertosaurus was a bipedal predator with tiny, two-fingered hands and a massive head that had dozens of large, sharp teeth. It may have been at the top of the food chain in its local ecosystem. While Albertosaurus was very large for a theropod, it was much smaller than its larger and more famous relative Tyrannosaurus, growing to nine to ten metres long and weighing less than possibly 2 metric tons. Since the first discovery in 1884, fossils of more than 30 individuals have been recovered, providing scientists with a more detailed knowledge of Albertosaurus anatomy than is available for most other tyrannosaurids. "
" Coelophysis and trithelodont. "
Coelophysis was one of the first hunter dinosaurs known, Late Trias (from 230 to 205 millions years ago), Arizona. 3 meters long, 1 meter high, weighing 15-20 kilos. Large and narrow, 27 centimeters long, head, thus stereoscopic vision. Hunted small fishs and the first small mammals that have ever lived on the Earth.
" The dinosaur Giganotosaurus carolinii, one of the world's largest terrestrial carnivores, reconstructed in the position where its fossilized bones were found, at the museum of Villa El Chocón, next to the hydroelectric dam of El Chocón, Neuquén Province, Argentina. ☺
Giganotosaurus is a genus of theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 98 to 97 million years ago. The holotype specimen was discovered in the Candeleros Formation of Patagonia in 1993, and is almost 70% complete. Mass: 4,200 – 14,000 kg (Adult) Eats: Santanaraptor Speed: 50 km/h (Adult) Length: 12 – 13 m (Adult) Family: †Carcharodontosauridae Fossils: MUCPv-95, MUCPv-52, MUCPv-Ch1."

I know this is late, but regarding scaling MCF-PVPH-108.145 from the 10.2 meter, 3.3 tonne individual, the 7.6-7.8 tonnes has a hole in it. That makes for a CONSIDERABLY more gracile animal than what Franoys gives (to be fair it is a juvenile as I said earlier, so it's got to be beefed up if it's being used for scaling), and scaling up from a 10.2 meter Mapusaurus which is in turn scaled down from Franoys' Mapu gives ~9.1 tonnes. I would lean more towards 8.5 however given how much food a 9.1 tonne predator would require.
Which was the first ? The first dinosaur or the egg where the first dinosaur came from ? (Stupid question, I know...)
Did all the cubs of dinosaur bear an horn to break the eggshell and did they lose it after ?  (12-12-2019, 01:45 AM)DinoFan83 Wrote: @GuateGojira That is completelly incorrect. The biggest Mapusaurus was at best about 6,950 kg based in the calculations of Franoys and that is the BIGGEST specimen found so far, from a considerable large sample. So no, the only carnivore dinosaur at this moment that can reach a figure of c.9 tons is Tyrannosaurus rex. I leave the image of Franoys for example:  *This image is copyright of its original author I already saw your posts in the topic of "Size Comparison" and you constantly use incorrect information about all the animals and downgrade T. rex at any oportunity with no reason, that is not fair and obviously shows a bias agains that animal. @JurassicDD already told you this, now I told you this too. Besides, about the comparison images you are using incorrect methods to scale the animals, it is not to enlarge them, you need to see if all the dimentions match. Example of this is your comparion between the jaguar and the Orinoco crocodile, which shows a croc with a skull of more than 1 meter, which is incorrect.

If you and me and countless other users on other forums (some forums he has been banned from) and many users on the Theropoda discord people that have all the latest data regarding the big theropods can not convince him nothing will.(12-12-2019, 01:45 AM)DinoFan83 Wrote: @GuateGojira You can lead a horse to water but sadly you can not make it drink it. He goes off on people being Tyrannosaurus rex fanboys but him being a Carnosaur fanboy is completely fine. Hopefully, the more people see these kinds of messages they will realize when it comes to some of these animals Tyrannosaurus and the big Carnosaurus especially he is not to be trusted and people should be skeptical about what he posts. |
