T.rex vs Spinosaurus aegyptiacus by ddinodan_
ddinodan_ presents a striking comparison between the famous Spinosaurus aegyptiacus and the newly discovered Tylosaurus rex. The artist playfully notes that Tylosaurus rex and Tyrannosaurus rex share the same mythical acronym: "T. rex".
Beyond the joke, the superimposition of the two images is superb and highlights the immense size of this mosasaurid compared to one of the largest carnivorous theropods. Obviously, they never crossed paths (and fortunately for Spinosaurus, given the size of Tylosaurus's jaws). A great way to celebrate this new discovery with humor.

Really gives you an idea of just how imposing they were.
That and it’s almost certain that Bunker is far from the biggest out there, especially with the new classification redefining the size pool for Tylosaurus, as even the smallest confirmed T.Rex specimen has been estimated at around 31 ft.

Is the new Tylosaurus rex bigger than Mosasaurus hoffmani?

From what I understand, it has a wider torso, but is likely shorter
Should be about 8400kg for Tylo (Bunker) and 8300kg for Mosa (Penza). Practically identical, with different shapes

They would have been similar in length (40-43 feet), but M. hoffmani is only known from cranial material, so restorations of its postcranial morphology are conjectural.

What kinda bullshit ass AI paragraph is that? That is so obviously ChatGPT’d holy fuck at least put a modicum of effort into your text.
The art is sublime, though.

La comparación es con el holotipo, nadie sabe que tan grande era un adulto de Spinosaurio

Yeah, pretty much anyone familiar with Spinosaurus knows that it could reach 13-15 meters based on the largest material, so it would have been of comparable length, if not slightly longer than "Bunker".

Unless I’m missing something, this image depicts T. rex as significantly larger than it’s actually estimated to be. It was still a massive and impressive animal, but it wasn’t 60-70 feet long, was it?

u/New_Boysenberry_9250 6d ago
Exactly, the artist didn't depict the largest Spinosaurus specimen, which would have been the same length or slightly longer than the biggest Tylosaurus.

They said Spinosaurus had an advantage in water but now he’s equally screwed /j

I mean, Spinosaurus and Tylosaurus were of comparable length but they also would never have met, due to inhabiting different biomes and different time periods.

I keep trying to say this people, Spinosaurus from some of the biggest specimens was a 50 nearly 60ft animal. Add that to the fact we just discovered a 2nd species of Spinosaurus, S. Mirabilis that could easily yield larger specimens over time. The fact is, Spinosaurus like Carcharodontosaurus and Giga have a much smaller specimen pool than say T rex or Allosaurus. This means that we clearly don’t know how big these theropods could have gotten but we know they were getting big. I dont get caught up in the comedic sometimes juvenile comparisons between the megatheropods because honestly speaking, no matter how it was built I have no doubt Spinosaurus would have been a very strong durable and powerful animal in life.

Spinosaurus did not reach 60 feet, those are outdated, high-end estimates. It reaching 50 feet are high-end estimates now.

u/Prestigious_Prior684 5d ago
“Nearly” not “did” thats why I said a 50 nearly 60ft animal. I have no doubt they could have gotten that big we dont have enough. And the key word u used is “now” just like a few years ago it was supposedly around 40 feet or so. “Now” its supposedly larger, there just isn’t enough fossil material for you to be so sure. 60ft, 50ft regardless is that this comparison is with a smaller animal definitely not a fully grown specimen which would have matched this Mosasaur in length

Bro, we work with the material we have. You argument amounts to little more than nothingburger speculation.

u/Prestigious_Prior684 5d ago
What was the point of that statement? Its not even an argument I’m agreeing with you that this comparison is with a smaller animal. Seriously please re read what u typed

So there’s T. Rex and then there is THIS T. Rex!! The tyrant king and the ultimate tile master king…One will take over your whole country and the other will just tile your bathroom expertly.
Seriously though, the convergent evolution is amazing. I know very well that evolution has clearly separated modern whales from these ancient sea lizards by millions of years (and evidently modern whales are descendants of Indian deer!!!). Yet, how incredible is it that they took on such similar forms. I’m convinced that if we all go extinct then some land living cephalopod will gradually evolve to walk upright with an endoskeleton and forward facing eyes, and will drive cars and fly in airplanes, etc.

Hard to believe that the largest creature to ever exist is the species thats alive today! (Blue whale) i always assumed it would’ve been something from one of the prehistoric eras

Great illustrations and an interesting comparison.
Do you have a link to a high-res version?

u/kurtchen11 8h ago
This seems to be a very average/below average spinosaurus aegyptiacus estimate but the maximum estimate for tylosaurus rex. T.Rex is pretty confidently meassured at 13.2m, upper estimates for spinosaurus go as far as 15m (13-14 beeing more likely).
Weight estimates for spinosaurus and the largest known mosasaur specimen are also pretty much identical at ~8 tons.
All in all i say this is not a great size representation.

This is the first time a size comparassion image had actually made me Understand the scale of something, usually my brain just says "oh thats a really Tiny person) instead of (oh thats a big animal), this just completelly overthrew that though, T. REX IS ENOURMOUS
