Prehistoric Breakdown: Saurophaganax 

Saurophaganax is a cool Dinosaur and needs some more recognition so this video is really awesome and cool

I just wanna say, dinosaurs couldn't roar. They didn't have the voice structure to produce roars.

I love it when stories have continuations :3

Amazing video glad to see saurophaganax in one of your vids . I hope to see torvosaurus in one.

Your videos are great! the stories at the beginning are very entertaining and the information part is amazing too

Honestly, I don't mind Saurophaganax being either a basal Carcharodontosaurid or a larger Genus of Allosaurid within Allosauridae. I always figured it was either of those two options. I mean looking at the reconstructed skull in the Sam Noble Oklahoma Museum of Natural History, it looks either like a Carcharodontosaurid or a transitionary form between Allosaurus Fragilis and what could've been THE first Carcharodontosaurid from North America during the Late Jurassic but became extinct before that could "come to fruition". After all the Genus Allosaurus lived in North America for 10 million years (neverminding the species A. Europaeus that probably lived through the rest of the Jurassic Period in Portugal), so why shouldn't the namesake of the family Allosauridae have another species that probably evolved from it? Granted yes we'd need more specimens and use phylogenetic bracketing to fill in the gaps, but even so the bones we have of it date to only 151 or 150 million years ago so something definitely happened as A. Jimmadseni (the oldest species of the Genus) evolved into A. Fragilis but perhaps also evolved into a new Genus entirely. It's not impossible for that to be the case, but as I've already said we'd need more proof regardless of new papers because that always change too.

I agree with the quite well-founded opinion among many respected paleontologists that the so-called “Saurophaganax”--which has always been at least to a *significant* degree, a *hypothetical* construct based on extraordinarily fragmentary and supposedly “rare” fossil evidence--is *not* a separate, “new” species of giant Late Jurassic therapod predator at all; it was merely, if the way the questionable fossil evidence has been interpreted is correct and it existed at all, it was merely an abnormally large Allosaurus with a few cosmetic skeletal peculiarities that *certainly* don’t differ from Allosaurus fossil evidence *so* significantly as to qualify as morphological distinctions between *two* separate but obviously related species. Claiming that “the rarity of Saurophaganax fossil evidence indicates that the predator must have been a RARE ANIMAL” solves nothing, as it is based on the logical argumentative fallacy of *hysteron proton,* which means that one puts *first* what should logically come last--in other words, when one commits this argumentative logical fallacy, one begins one’s “argument” by groundlessly ASSUMING the **very thing one is theoretically attempting to prove.** This, sadly, is **yet another** example of paleontologists discovering fossils that at first *appear* to have unusual features, and then jumping to wild, huge, hastily generalised conclusions because of the notorious paleontological ego’s insatiable NEED to get credit for supposedly “discovering a new species of dinosaur.” Nothing more.

Anything on Sonorasaurus? Quite little information on that dinosaur.

nice video

Heeeyyyy, Raptor Rex, Whaaaat's happenin? Yeaahh Hi, I'm gonna need you to do a breakdown of the Chilesaurus, mmkay? Yeaahh, apparently Its a, uh, plant-eating "platypus" dino which may in fact be the, um, missing link between the Saurischians and Ornithiscians, making it one of the most basal dino species? If you could get that in for me in the near future that would be terriiiiific. Great, thaaanks!

You should do barsbolia if you haven’t already

Its not at all unreasonable to believe that there could be two species of allosaurus in the same region, when you consider that leopards and tigers(or lions if you like) belong to the same genus and coexist through different predator niches. Also consider that a tiger is about 4 to 5x the size of a leopard, so who knows how big the saurophaganax/allosaurus maximus could've gotten???

Personally, I believe it’s it’s own species

Woo-Hoo!

Currently saurophaganax was reclassified as a charcarodontosaurid. Makes alot more sense as to why was so large. Also i think the cera revenge thing is going a bit too far. And it is almost certan theropods couldnt roar. And more so that they didnt hunt in groups.

Saurophaganax isn't 4 tons or 13 meters. Saurophaganax is 12.9 meters long & weights 8.3 tonnes. It's currently the 6th largest carnivorous dinosaur and the king of Jurassic

I personally believe Saurophaganax was probably just a large sub species of allosaurus or was a genus. It’s definitely not it’s own thing imo.

whos here from PE?
