How big is your favorite dinosaur? by ScottHartman How big is your favorite dinosaur? by ScottHartman
Now before you start freaking out, note that the T. rex specimen is Sue (i.e. the largest T. rex) while the Triceratops and Stegosaurus specimens that I restored are one the smaller side. For that reason I included silhouettes of known larger specimens to provide a better estimate of the overall size range. I couldn't do this with Apatosaurus or else everything else would have gotten too small.

Finally, note that Velociraptor is the actual skeletal, while the gray silhouetted dromaeosaur is Deinonychus, not some giant specimen of Velociraptor.

Enjoy, and if you have some good ideas for other comparisons let me know, I'm officially taking suggestions right now.

Add in a Pteranodon and take out the raptors, and you have all the classic Dinobots from the original Transformers series (though, if Sludge were a real Apatosaurus/Brontosaurus, he'd seriously dwarf the others).  =P Yes, I know Pteranodon is not a dinosaur, but that's never stopped the media from including it in with the other "stock" dinosaurs.

Guess there wasn't much space for the OMNH mega-Apatosaurus, was there?

And that one wasn't even mature yet. An SVPCA 2013 abstract implies that a hypothetical adult Apatosaurus would probably have been twice as massive.

Yeah, if you read that abstract (I posted in on my journal entry here: fav.me/d6rvw8d), it implies that through the notion that the fusion of the cervical ribs comes after neurocentral fusion, along with comparisons with Diplodocus and Giraffatitan.

Assuming that CM3018 would have had a mass of ~25 tonnes, then, based on the implications of the abstract, the Oklahoma Apatosaurus would have massed in at ~50 tonnes, and a hypothetical mature Apatosaurus would be at ~100 tonnes omfg


And yet, the JPW site depicts Tyrannosaurus as larger than Apatosaurus :facepalm:
But I guess that with their kaiju mosasaur thing, a kaiju tyrannosaur isn't too far off...

A question:

Is a comparison of individual bones from two taxa that's only distantly related(like a comparison of an Albertosaurus D5 and a Baryonyx D5) really a good method for estimating the relative/comparative body masses?

Not particularly, although you could potentially use them to scale up more complete specimens, which wouldn't be the end of the world.

:iconspinoinwonderland:

Ok. But those extrapolations would have monster error bars then, and thus should only be used if closer relatives aren't available. Thanks!

Wow,thank you...I mean I knew this one already (like probably all your work here on dA),but Iīm flattered you took the time to answer this,sir...as Iīm at it,since Iīm a huge dragon fanatic as well as totally in love with really realistic dragons,is it ok to `downloadī your pictures (of theropod anatomy,mostly) for my  personal use as reference points for drawing/painting?
They could also come in handy when I really go into makin my own maquettes for lighting-the James Gurney way.

Iīm somehow very sure you know who that is,donīt ask me why...hm...
 
If you should ever have some spare time to spend,might I perhaps ask you for the big favour to take a peek over my latest (and therefore best) Dragon picture?
It is a portrait, so-to-say,on which I took 35+ hours to make it as believable I could,even using reference this time,one part of that being the JP-T-Rex of course.
The critical eyes of a real expert would be an inestimable ... ... ... push for my ego as a dragon designer(as long as we let the throat sac aside).

Btw., would you say Iīm right with the impression that,when it comes to the illustration of large theropods(especially of course the "Rex" and the Spielb...Utah-Raptor),Jurassic Park was a real "Year 0"?

Oops, I missed this for quite a while. Yes, I'm familiar with Mr. Gurney. As for JP being a year zero, I would say no. If anything 1986 or 1988 were year zero for illustrating theropods, as the combined works of Bakker (The Dinosaur Heresies) and Paul (Predatory Dinosaurs of the World) had already shifted paleo-illustration irrevocably onto a different path. What Jurassic Park represents is when mass media brought the new look theropods to the awareness of the general public.

Its a guess: based of other t-rexes. Maxilla's skeleton was a small fragment of the Jaw. nothing else was found. BUT they did say(sorry i didnt put it there) that its no guarantees. t-rexes variate alot in size and shape. they found one they thought was 21 meters long but just had wide hips. heres link with the info.

ps: ive seen ur name, i think. u think t-rex is weaker than spinosaurus and ALOT of big theropods. but im kinda a fanboy. my top three dinosaurs is: 1:T-rex 2:Spinosaurus 3:Giganotosaurus.

Dude, Topix isn't really a credible source. It's filled with trolls and fanatics. It's a bit like Youtube without the videos.

And you better lose that bit of fanaticism, it's bad for your potential credibility. Fanboys/fangirls don't give others good impressions of themselves.

And I think Tyrannosaurus and Giganotosaurus are rough equals. Spinosaurus is stronger than both because it's larger, and stating otherwise is going against the laws of physics itself. If Tyrannosaurus is truly your #1 dinosaur, then a true Tyrannosaurus fan does not try to exaggerate Tyrannosaurus, but goes for the most likely truth about it.

As some kind of a T-Rex fanboy myself,I think I have to contradict firmly here..a true T-Rex Fanboy will (like me) always just believe that,one day,science will find a specimen (completely remaining,of course) of a T-Rex thatīs much larger than any Spinosaur reasonably to be assumed.

THE 40 METERS TREX IS NOT A LIE.

It will also find that tyrannosaurian feathers can easily withstand nuclear blasts. Tyrannosaurus can also eat an entire Godzilla-sized kaiju with ease.

(I can only assume that your post was intended to be a joke, so my above reply isn't serious either)

PS: There is a very distinct and wide divide between true fans and fanboys/fangirls.

Well,letīs say it was a half joke.
Of course I donīt believe a 40m theropod is to be found,but,on the other hand,the fact that we have found approx. 1% give or take of the approx. 1% (give or take) of fossils that remained from all the lifeforms that ever existed on this planet leaves plenty of space for fantasy...and wishful thinking :)
Letīs say the 20 meters T-Rex doesnīt necessarily have to be a lie.

SpinoInWonderland Featured By Owner Nov 29, 2013
Fantasy, by it's very definition alone, has no room in science. The wishful thinking has a remote chance though, as long as it's plausible, for example: no kaiju-sized brachiosaurids.

And despite the massive amount of undiscovered taxa, they are all constrained by three factors: physics, biomechanics, and lifestyle. There's a reason why there are no spiders the size of a tiger. Tyrannosaurus is a cursorial predator with adaptations for running, so it cannot really get to titanic sizes, because of it's limb biomechanics and it's lifestyle. It's not a therizinosaurid or a spinosaurid which had lifestyles(herbivorous and piscivorous respectively) that have no need of running/cursorial ability, and thus had access to larger potential sizes. Still no ~20-tonne Spinosauri though, for the same reason as why there are no 50-kilogram ants or no 15-meter Tyrannosauri.

If you inflate a Tyrannosaurus to ~12 tonnes, for example, it would be very slow and in no condition to hunt. A ~20-meter Tyrannosaurus would be around ~29-30 tonnes in mass based on AMNH 5027(assuming a ~6-tonne total body mass for this specimen), and you know that such a size is clearly not physically possible for a cursorial biped, or any biped on Earth for that matter(rearing sauropods don't count as bipeds). It's ill-adapted legs would cave in on themselves, the poor creature would collapse and be at the mercy of any predator or even scavenger that came at it for a free meal.

If only the moon had a breathable atmosphere and adequate water, ecosystem, and environment, then you could possibly get a ~20-meter Tyrannosaurus in there and have it thrive. But that's clearly not the case.

Just so u know im kinda a t-rex fanboy. I dont freakout about JP3 but i exaggerate sometimes. like for a few days i believed my uncle who says t-rex has a 50 ton bite-force. and im not going in on a fight about t-rex vs Spinosaurus. they are both great and impressive animals. id rather leave Spinosaurus as he is right now. u have ur reasons to believe who wins and i do. can u delete comments btw(the ones u posted so ill delete maxilla ones)

Really cool. I personally would like to see Brachiosaurus. Not the African Giraffatitan, since its no longer known as Brachiosaurus, but B.altithorax, from the Morrison deposits. Another cool sauropod would be Argentinosaurus, although that might be kind of challenging. But hey, who doesn't enjoy a challenge.
