Size Matters: New size estimates & Specimens of the Large Prehistoric Animals

[Turkeysaurus]

Largest Iguanodon might be 13.5 m long , 10.3 tons.



10 meters for Iguanodon i think norm and it can be 11-12 as well. Hopefully Haolonggood will do at least 9 to 11 meters. 12-13 meters specimens are possible but too speculative for a figure imo. Anything from 26 to 32 cm will do fine. Somewhere in the middle would do even better.

If you want a big Iguanodon Collecta has one. People want a smaller 1/35 scale Iguanodon for a 9-10 meter individual.

I prefer 9-10 m  for a 1/35 figure as well, 11 m max. 12-13 meters range are not impossible but unreliable.

According to Vividen, he has seen Bertha specimens numbers and result is Bertha is larger than Scotty but not Goliath.

Interesting reading about Goliath.  Given that many new discoveries get sensationalized a bit (or a lot)it's best to wait until more detailed numbers and analysis are available to get a better handle on how much bigger than existing specimens it is.  Regardless, Sue, Scotty and Goliath seem to be all about the same size-ish.  Discussions about the largest are fighting over inches and really not important in any meaningful way to our understanding of the animal.   But these large specimens do confirm that Sue was not a fluke, unusually large specimen, but perhaps a more common size of older T.rex individuals.

Since these specimens are spread around in location, it could be concluded that they are not representatives of some larger sub species of T. rex from a confined geographical area (ie in the way that lions from south Africa are usually larger than lions from Central Africa).

So PNSO Acrochantosaurus is just a bit smaller or bigger than Haolonggood Tyrannosaurus now.    Also sauropods are quite a bit underestimated. 

In short: majority of dinosaurs should be estimated heavier. Some of them a bit, some of them a lot more. This works best if there is 3d skeleton so obviously better with dinosaurs that has got a lot of good remains.
