Megatheropods: Nature's Biggest Terrestrial Carnivores

Theropod dinosaurs are the most charismatic terrestrial predators in Earth’s history, with complex ecologies, physiologies, and evolutionary relationships. From movies to books to video games, theropods have left a cultural footprint unlike any other group of extinct vertebrates. And even these terrifying and majestic animals have an elite group within them: the megatheropods.
If all theropods formed the ranks of a military, then these are the officers, the generals, the supreme commanders. There are a few definitions floating around the internet about what exactly a megatheropod is, so here’s a modified version of mine from 2017. A megatheropod is any theropod dinosaur that consistently attains an average adult mass of 5000 kilograms or higher. This definition is more exclusionary than my old video, and that’s because while researching this I put an emphasis on consistency and utilizing multiple mass estimates per species from different sources, which I’ve linked here.

It's amazing, many Theropods rivaled or even surpassed modern elephants in weight, yet they were still dwarfed by many species of Sauropods. Between the Dinosaurs on land, Pterosaurs in the air, and the massive marine reptiles in the oceans the Mesozoic truly was a world of giants.

Carcharodontosaurs on average are head and shoulders above tyrannosaurs and spinosaurs. I conducted a literature review for my Comparative Vertebrate Studies course (using only peer-reviewed sources, so they ran on the low side) that resulted in an average tyrannosaur mass of 2875 kg, a spinosaur average of 2804 kg, and a carcharodontosaur mass of 3434 kg.

All while being larger than an a full grown Elephant. Edit: Also. These are just the Megatheropods that were discovered.

[@Tyrannosaurus_rex.]

Some of these estimates were surprisingly low. I always went with a 9,200kg average Tyrannosaurus. Seeing as Scotty could be 10,600kg to even 11,000kg and Sue being 9,900kg to 10,200kg. As Sue isn't exceptionally large compared to other specimens, I would think the average would only be a tonne off. My reasoning is bad but I saw that Sue was upscaled from 8,400kg to over 9.9 tonnes and Scotty was upscaled from 8,800kg to 10,600kg to 11 tonnes, I just assumed that all the other specimens should get a buff. I used Scotty, Sue, Stan, Trix, AMNH 5027 and the holotype specimen to find an average. I know my reason isn't very backed up, but I like to theorise about Tyrannosaurus, hence my name. Super interesting video!

[@Cope_Paleontology]

I agree with you, a tyrannosaurus weighing 9-10 tons looks much better these days, his estimates for giganotosaurus are very high, I always see that giganotosaurus estimates are around 6,500 to 7,800 kg.

[@antoniocenteno1483]

@@Cope_Paleontology They are too high, 8.4 Tons was the potential weight for the bigger Giga found of wich we only have the dental record, wereas 6.5-7.8 was the weight of the holotype specimen. Unless he is taking in the bone density studio for wich all theropods "got a boost" but then the Rex should be about 9 tons for the holotype whereas scotty pushed 10 tons. I learned that on this channell lol and now i´m confused.

[@TheVividen]

All of these estimates were using the .97 median density from Larramendi et al. (2020). I didn't use the 2013 Hartman estimates because he redid them in 2020 and got much higher numbers for both Tyrannosaurus and Giganotosaurus.

[@TheVividen]

I'm glad you liked it! Statistically neither Sue nor Scotty would be considered "unusually large" since their masses didn't land more than two standard deviations away from the mean of Tyrannosaurus. I like your approach, too--it's always good to use multiple methods.

[@Tyrannosaurus_rex.]

​​​@@TheVividen yes, I understood that Sue and Scotty weren't exceptionally large, so the average can't be too many tonnes off their weight. I found an average using the low estimates of: Sue (9,700kg), Scotty (10,400kg), Stan (8,000kg), holotype (8,500kg), Trix (9,500kg), AMNH 5027 (8,300kg) To get an average of 9,067kg I then used conservative estimates: Sue (9,900kg), Scotty (10,600kg), Stan (8,700kg) holotype (9,000kg), Trix (9,800kg), AMNH 5027 (8,800kg) This gave an average of 9467kg Then the semi-high estimates: Sue (10,100kg), Scotty (10,800kg), Stan (8,800kg) holotype (9,100kg), Trix (10,000kg), AMNH 5027 (9,000kg) This gave an average of 9634kg Finally, I used the higer estimates for these specimens: Sue (10,200kg), Scotty (11,000kg), Stan (9,000kg) holotype (9,300kg), Trix (10,100kg), AMNH 5027 (9,100kg) This gave an enormous average of 9784kg.

I’m happy you at the end of the video pointed out the alternative that Giganotosaurus could be smaller than what the evidence shows us, in which, just like your conclusion, our evidence is very much our best guess. I see so many people say “Well, Giganotosaurus could be larger” but the opposite is very much equally as applicable. We don’t really have a quantifiable average for even Tyrannosaurus, let alone something like Giganotosaurus, so the room of improvement or lack of improvement arguments regarding size are statistically applicable all across the board of Theropod genre for “It could get larger” or “It could get smaller”, since these are just fossils. Our evidence is our best bet which we can claim.

[@TheVividen]

That's completely correct. I ran a one-way ANOVA analysis of the average tyrannosaurid, carcharodontosaurid, and spinosaurid mass and got a p-value of .746, indicating that there was nowhere near enough evidence to suggest that the true average masses of any one of those clades was different from the others. We'd need far larger sample sizes for all three groups to confidently say that we have a statistically significant difference between them.

[@Cosmo-Kramer]

@@TheVividen The body mass differentials may prove in the long run, with more fossil findings, to be somewhat different plus or minus for Gig and Spino, but we have enough Rex fossils to know it won't vary much at all, plus or minus, with additional findings. And in determining the baddest therapod to ever live, it's not all about body size. One of the reasons Rex has, since its discovery, been considered the literal king of carnivorous dinosaurs is because of its teeth size and bite force. We don't need any more fossils of Gig or Spino to know that they are no match for Rex in destructive power in their jaws.

Interesting way to break things down. I think it's likely that T-Rex went through all of your stages as it grew. With the growing evidence that tyrannosaurs functioned in family groups (small packs, much like modern predatory raptors), the most likely biologically plausible explanation is that, upon attaining full size, T-rex acted less as the primary killer of game....and more to protect that game from smaller predators. The younger tyrants probably did most of the hunting, and then the whole family got to eat their fill, because the mature tyrant was there and nothing in the environment could possibly challenge it. Basically, they had "old man" strength and while they lost their speed....they earned their keep by being able to keep anyone from messing with the kills their younger children took. Then, eventually, a family group would meet up, swap kiddos, reproduce, the older tyrants would die (explaining why t-rex only spent a small amount of time as a full size adult), their kids would take over the two family groups, and rinse and repeat. Everything has to be viewed from the perspective of actual biology. T-Rex, as an adult, was so massively overbuilt that was slow. I would argue that's not because it was a scavenger....but because it had the family job of making sure nobody could move in on it's kids. basically, it's the oldest play in the book. F* about and find out.

[@bluemouse5039]

Looking at Reptiles today none of them seem to have any type of family units, they are loners that only get together during mating time and protect eggs or the young for a short time but will go back to being solitary animals and even prey on their own off spring once their short period of maturity instinct wears off, They will gather in groups not to work together out of any kind of family bonding but because they gather where the prey animals are and will tolerate others of their kind long as they keep their distance or not try to take their kill from them , when they eat on a carcass there is no social order its who ever is aggressive enough to take what they want first , the bigger ones will usually intimidate the younger ones away but are not above killing a smaller one of its kind and eating it if it gets in the way, That's how Crocodiles, Alligators and large lizards like Komodo dragons and Monitors are and also many mammal predators like Bears, Tigers, Wolverines, Which makes me think if a T Rex is a solitary animal as well and doesn't have a permanent family unit, i don't think they had the intelligence to have a pack mentality or complex social structure like wolves or lions

[@Ring3R]

@@bluemouse5039 Except dinosaurs were archosaurs - and that's very different from other reptiles. The two surviving clades from that group are birds, and crocodilians (and, maybe, turtles, jury is still out on that). Those groups all have parental care. Some of them, particularly the ones that directly descend from the dinosaurs (birds) have numerous examples of parental care, family groups, high intelligence, mating for life, protection of young, the list goes on. Given the evidence we have of severely disabled therapods surviving months, or in some cases, years, it's pretty obvious these animals had some kind of social structure. Given that we see the same sort of thing in their direct descendants (birds), I'd say that, if they were not pack hunters, they were at least family hunters.

I love the book that you got some of the artwork for this video from. If you don’t already have it, you should get the book about sauropods from the same authors. It has some of the most beautiful depictions of sauropods I’ve ever seen. They’re unique, colorful, and like the theropod book, it has reconstructions of very lesser known or undiagnostic specimens. It would be awesome to see a video about mega sauropods too since their book has an exhaustive list of every sauropod with cited length and mass estimates. 30 or 35 tons (about the mass of a humpback whale) would be a good place to put the threshold and includes tons of unexpected giants besides just titanosaurs

[@SergeantBrowning]

I think regardless of which comes out bigger, T. Rex or giga, the real question is how their weight distributed? Giga when you look at its skeletal structure is a leaner quicker hunter. It looks like it’s built to bleed its prey then finish it when it’s weak. T Rex looks to have been built for a marathon chase leading to a climactic showdown when its prey could no longer run away. It had exceptionally keen vision and smell, and it was obviously built to deal kill in one or two chomps. Even if Giga is found to be larger I think the answer to who would win a straight fight would still go to the T Rex most of the time. It’s built for head on conflict with animals in its weight class. Evidence points to Giga bleeding out large slow animals or catching smaller weaker prey. Both amazing in their own right, but only one gets to wear the belt lol

Comparing modern elephants to megatropod dinosaurs is impressive on both counts. On the one hand, megatropods include carnivorous dinosaurs that were larger and heavier than a current African Elephant, that is really terrifying, an African Elephant is already a huge beast in itself, luckily it is herbivorous, but imagine a more predatory animal bigger than him. On the other hand, we can see how a group of the largest current land animals could be capable of scaring away or defeating a megatropod such as T-rex or Giganotosaurus in a dangerous encounter, Elephants are intelligent, perhaps they would be afraid to see a predator something bigger than them but they know that together they can beat it, a normal adult Tyrannosaurus rex of about 8-9 tons would see a single African Elephant as a good prey, but a herd of them by no means, each of them weighs 6 tons and they are close to their height, the T-rex only outnumbers each one by 2-3 tons, if we have about 6-7 Elephants facing a Tyrannosaurus, the dinosaur would basically be far outclassed in strength, it's just It is a matter of thinking that a Triceratops (the most dangerous natural prey of the T-rex) counts almost as 2 current adult male African Elephants, if a T-rex encounters about 6 Elephants it is like it is facing 3 Triceratops, the best option of the apex predator would be to run away if you don't want to earn a beating.
