Mapusaurus | The Giant Killer of Late Cretaceous Argentina

What is worse than a giant, hungry, bloodlust theropod? Seven of them, and that is exactly what you got with the Mapusaurus, an almost perfect replica of Giganotosaurus, which loved to hunt in large packs, in order to take down the largest of the large, the Argentinosaurus. This carcharodontosaurid ruled Late Cretaceous Patagonia (Argentina) with an iron fist for millions of years, causing fear among all dinosaurs and especially in the sauropods. It was the perfect killer, bearing razor sharp teeth that cut through flesh like a hot knife through butter and “fortunately” for the Argentinosaurus, increased its deadliness by pack hunting with other Mapusauruses. This was truly a terrifying sauropod killer who was unchallenged as the apex predator and would make any theropod proud!

For someone reason, the situation with Mapusaurus and Giganotosaurus reminds me of Bumblebee and Cliffjumper from Transformers. If you don't know, those two have very similar designs, so the fandom usually views Bumblebee as the famous one, while Cliffjumper is mostly known as the one that looks like Bumblebee. It's kind of the same here, Giganotosaurus is the famous one, while Mapusaurus is mainly known as the dinosaur that looks like Giganotosaurus but isn't. Luckily, after Planet Dinosaur, it seems Mapusaurus is getting the recognition it deserves.

This is slightly outdated, Mapusaurus currently sits at 7.91 tonnes and 12.3 meters, making it the second largest Carcharodontosaurid. It and Giganotosaurus we're both extremely fast for their sizes. Mapusaurus most likely did hunt alone, only grouping together when there's 1 large prey (Like a group of Argent's), similar to Allosaurus. BUT it most likely wasn't chaos, forming a loose pack, using tactics, but they would eat or attack each other if one was dead or extremely wounded. However, it was unlikely, but it could've hunted it groups. An amazing theropod for sure.

Mapu, Giga and the other SA Carcharadontids lived among a lot of sauropods, not just giants. I think it may be a bit of stretch to think they were hunting some of the largest sauropods in history when there were so much smaller and manageable genera of sauropod in their environment (Rebbachisaurids in particular only got to around 7-8 tons) and were plentiful / diverse in formations with giant Carcharadontids.

If they did work together, "a stretch", then it would be feasible for them to take down larger prey. Its very unusual for lions to hunt elephants but it has been observed and documented.

It cracks me up when experts try to put some specific behavior on a 65+ million year old animal. The fact is we will never truely know how these animals hunted. Just like lions today are predominantly group hunters and tigers are solitary. Both large cats with different lifestyles. Even though lions live together I'm fairly certain it's exceedingly rare for them to all die together. Point being, in 50 million years when some paleontologist unearths a lone lion skeleton. Will they automatically suggest that lions were solitary hunters? Not everything fits into the same box. Nature is diverse. There are many examples of animals with similar anitomical features that have completely different lifestyles. There are just some things we will never know. For someone to act like they do know because their an "expert" is ludicrous and narcissistic to me.

@Ewan Callister they would bleed out prey, but they wouldn’t just bite prey and wait like often assumed.

If they did participate in pack hunting I suspect it would be like what is seen in modern birds where individuals would only come together by circumstance to take down large prey but don’t live together.

Allosaurus did give rise to some special predators.

They probably had learned/pack behaviors, and hunting strategies. We need to start considering more and more that these creatures were possibly social, as they were non-avian dinosaurs (bird relatives) and they likely had hybrid traits, with reptile tendencies. I, personally, believe that convergent evolution not only brings back homologous structures in different species of animals and lifeforms, but also behaviors. They may have had wolf like pack mentality.

The idea Mapusaurus or any other carcharodontosaurid was a flesh-grazer is based on nothing besides then having slicing teeth (which were much more likely used to outright hunt prey, not to act as a giant parasite). Also, the common idea of carcharodontosaurids biting prey and then just hanging back and waiting for the prey to die of its wounds is based on false ideas about how modern predators that rely on shock and blood loss kill prey. In reality, such predators either try to target internal organs to kill on the spot, or attack relentlessly (biting repeatedly in a sustained chase without just waiting for the prey to keel over) until they make the kill, and carcharodontosaurids wouldn’t have been any different.

[@Cedrick_2005]

I totally agree with your comment. I can imagine a pack of Mapusaurus hunting the same way a pack of African Wilddogs, Hyenas, and Wolves would hunt much larger prey. They would relentlessly bite their prey until it collapse from blood lost. I would also imagine these giant predators would eat a Sauropod alive. I also find it hard to believe that some scientists would believe animals as big as Mapusaurus or T-Rexes would be mostly scavengers when most scavengers we know of today don't get very big. An animal that big couldn't get that big mostly scavenging they would need fresh meat to sustain that size.

[@bkjeong4302]

@@Cedrick_2005 you’re spot on with your comment on how big canids relentlessly attack prey until they bring it down; especially as wolves have laterally compressed canines (unlike big cats, which have conical canines) to better facilitate slashing. Carcharodontosaurids were much more specialized for slashing and cutting through unarmoured prey, through, due to a series of cranial and cervical adaptations convergent with those of sabretoothed cats (which, unlike big cats proper, relied on quick cutting bites rather than a powerful jaw grip to kill prey)

[@Cedrick_2005]

@@bkjeong4302 here's my theory on animals like Smilodon, I believe they suffocated their prey similar to big cats today.

But it wasn't meant for sauropods, because sure, landing such a bite will hurt, but trying to bite something that can literally one shot you, it is too risky and foolish for even a Tyrannosaurus to try. In short, all of T. Rex's prey options evolved in ways to counter Rex's bite whether that be sheer size/strength or armor and weaponry, which certainly gave Rex trouble as some could even spell doom for it in 1 hit alone. So, tell me why the fuck a Tyrannosaurus would think it be a good idea to try and take down an animal that weighed 38 tons and can easily crush it to death if it stomped on it? The answer is no.
