best scale I've seen so far!

Tyrannosaurus isn't looking too powerful right now! :D (Big Grin)

Would you mind if I put flesh on these skeletals you've made?

OK, you can put flesh on these skeletals under crediting me (e.g. "based on GetAwayTrike's skeletal reconstruction").

Great use of a scaling and study on the fossils. Even if the Spinosaurus material is well...quite lacking I'm sure yours is accurate enough.

Mind if I use this for a height chart by any chance?

Yes, you can use for basis of your chart.

Thank you! And you're very welcome. I need to measure out the femurs of each theropod do where their heights stands out so this will help.

how long is your Carcharodontosaurus saharicus  ?
Reply
:icongetawaytrike:

Around 13.5m, roughly measured.

I have no clue on how an estimation of 13,5 meters is possible for SGM din 1, by simple skull scaling from Giganotosaurus and Tyrannotitan such a size is not possible, specially when your Giga holotype skull is the exact same size or bigger than the skull size of SGM din 1.

Also if it was 13,5 meters, or 13,4 as I got measuring using the preserved portion of the skull as scale, it should be longer than your Giganotosaurus holotype, which is between 0.7-0.9 meters shorter than that apparently. Furthermore such a big SGM din 1 is even bigger than the biggest length that has been ever suggested for it in the scientific literature, which is 12,8 meters long in Brussate and Sereno 2007. It also appears that you didn't take into account the documented remains of IPHG 1912 into account as described per Stromer in 1931.

Nobody knows the exact proportions of Gigantosaurus or Carcharodontosaurus so far at the moment. Thus, numerical estimation and skeletal reconstruction always contain error.
IPHG 1922 X46 is smaller than SGM-Din 1 and may have some differences in proportion. So I ceased to combine IPHG 1922 X46 with SGM-Din 1.

Yes but what is the consistency between your estimation for Giganotosaurus and Carcharodontosaurus, when your Giganotosaurus has both a bigger skull and a smaller body than your Carcharodontosaurus? Did you just give Carcharodontosaurus completely speculative post cranial material instead of trying to scale it? It is completely impossible to get a estimation of 13,5 meters scaling from anything unless you do the post cranial material in a arbitrary manner.

I'm aware that different individuals might have different proportions, but I'm sure Carcharodontosaurus neotype would, almost certainly, be closer in proportions to another specimen of it's species (which was classified as adult by Stromer despite it being smaller) than a completely speculative restoration of it.

I really don't want to be harsh to you and please forgive me if it seems like I'm being so but I still wanted to state my observations and opinions on the matter.

Giganotosaurus must be larger based on available specimen, off course. The total length of Carcharodontosaurus was roughly measured too much by my fingerI am a dummy! 

Aside from joke, there is not much significance in detailed comparing the total length based on skeletal drawings. For example, exact estimation of the length of the tip of tail  and cartilage difficult..

Well the point is that your Carcharodontosaurus is bigger than your Giganotosaurus holotype, at least it was when I scaled it using the measurements of the partial skull in Sereno 1996, and it seems to differ from the sizes yielded by the scalebar, but perhaps it is an issue of the downloaded image being very low resolution, I still would recommend double checking since the whole point of the comparison is comparing the sizes of the things, so they must be scaled correctly.

If you want to measure things more exactly really quickly, here is a very useful GIMP plugin that can help you measuring the lengths along the curvature (if you don't do it alredy) ; registry.gimp.org/node/17235.

Here it is how to install it: en.wikibooks.org/wiki/GIMP/Ins…

The scalebar seems to be off, I think you made it 3 feet instead of a metre, that would make the actual thing 90.12cm.

I see you based the Carcharodontosaurus on Giganotosaurus, isn't Tyrannotitan closer to it than Giganotosaurus? And if :iconfranoys:'s skeletal is accurate it'd be more than just a headswapped Giganotosaurus.

These are minor differences between Giganotosaurus and Tyrannotitan (and Carcharodontosaurus). We cannot know exact height of Carcharodontosaurus's neural spines.
Note that cervical spines of Tyrannotitan are broken. Tyrannotitan (, Giganotosaurus and Carcharodontosaurus) have relatively high cervical spines probably.

That is true, but if the skeletal below is accurate there would still be a difference in proportions between the two.

His (and GSP's, Hartman's, etc...) skeletal looks like largely based on outdated artifacts of the restored skeleton of Giganotosaurus.
e.g. scapula (as noted by Canale et al., 2014) and ilium must reconstruct be longer as other typical carnosaur (e.g.Acrocanthosaurus).

Hi :icongetawaytrike:, I've trying to get the source for that but I didn't have any luck, however, I've seen the artificially unexpanded distal end in the scapula  mentioned in the Theropod Database and apparently Carbajal and Canale mentioned it but I can't get any detailed explanation. Would you kindly provide the source?

Thank you in advance.

Scapula of Giganotosaurus is poorly preserved (Canale et al., 2014). Acrocanthosaurus has long slender scapula as standard for carnosaur.
We DON'T have any evidence that scapula of derived carcharodontosaurid is short.

Siats is too fragmentary.

We can reconstruct MEDIUM megaraptoran based on Murusraptor, Aerosteon, and Australovenator.
However, for example, medium tyrannosaurid (e.g.Gorgosaurus) and large tyrannosaurid (e.g.Tyrannosaurus) is quite different.
Thus, I don't draw Siats skeletal for now...

Notes:
My old composite megaraptoran (some deviant artists using my composite megaraptoran as basis for their megaraptoran skeletals) has some important errors.

Also, Siats is shorter than Saurophaganax.
9.9 meters for Siats, and 10.3 meters for Sauro.

Yes I know, I worked on Spinosaurus skeletal too, it just looks "strange" to my eyes because sacral neural spines are short and I remember a  Spinosairus neotype picture with a longer posterior spine:)
