Size comparison scale

[roninwolf1981]

Has anybody done a Ceratosaurus vs Carnotaurus one yet?

[dinosauria101]

roninwolf1981 , here. I think the member Spinodontosaurus made this

[Infinity Blade]

Limb bones of a 5 week old male broiler chicken (left) vs limb bones of a 6 week old male (cross-bred) red junglefowl. Yes, this is to scale.

Tyrannosaurus specimens Sue by Franoys with Scotty by Randomdinos comparison made by Maxilla

[dinosauria101]

Largest Ruyangosaurus specimen, 31 meters TL, 60 tonnes, subadult. This is by Paleo King (from here).

[dinosauria101]

Holotype of Huanghetitan ruyangensis (24.36 meters standing length, 73.3 tonnes) vs extrapolated adult OMNH 1670 Apatosaurus (37 meters TL, 100 tonnes).

[dinosauria101]

Palaeoloxodon namadicus (500 cm SH, 22 tonnes) vs Dreadnoughtus (26 meters TL, 48.45 tonnes, still a juvenile).
Elephant side and top view are by Larramendi while Dreadnoughtus top view is by palaeozoologist and side is from the discovery paper.

I see a bit of differences between the 2 Rex specimens.  I'm suspecting sexual dimorphism...?

[dinosauria101]

^I believe that's merely due to individual variation; we have no evidence on the gender of either specimen.

[dinosauria101]

Palaeoloxodon namadicus (500 cm SH, 22 tonnes) vs Huanghetitan ruyangensis (~30 meters TL, ~62-73 tonnes depending on how it's restored). Side and top views for the elephant by Larramendi while sauropod side view is by Paleo King and top view by Greg Paul.

[dinosauria101]

Huanghetitan ruyangensis (30 meters, 62-73 tonnes) vs BYU 9024 Barosaurus (50 meters, 100 tonnes). Skeletals by Paleo King and Hartman.

Didn't SVPOW give a weight of around 66 tonnes for a 48M BYU-9024?

Did they? I am not aware of this.
That cervical (most likely C9, but could be anywhere from a 7th to 11th) is exactly twice as long as that in the corresponding cervical in the AMNH Barosaurus (estimated at 12.5 tonnes IIRC), and scaling from it gives 100 tonnes.

Ah, I see.

I suppose the size estimation would depend on where you think the cervical would be.
