Some Shantungosaurs bones

Following from the last post, here’s a few Shantungosaurus elements that are on display. The skull is about 90% reconstructed but collectively there’s probably a near complete skull in the collections (i.e. cobble all the skull bits together and you have nearly the whole thing covered) so it’s pretty accurate. There’s also a bunch of bits in a cabinet (for reference, the rib fragment is about 2 ft long), a sacrum, and a *small* selection of *some* of the femora that have been dug up so far.

    Wow, there’s more thigh on display than in a can-can line!

    The last photo in the previous article (with a standard Doctor Hone for scale) appears to depict a mount of around 14m in length, altho’ perspective makes that a bit iffy. Is that about right?

    If so, that would make it the largest non-sauropod herbivore (and it achieved that length without cheating by having a long neck!).

      Yep, 14+ m is pretty much it.

      It’s certainly longer than any other ornithischian I can think of and probably heavier too. I have heard rumours of other very big specimens of hadrosaurs, but based on what I know of, this is the biggest going.

        From what I recall, Lambeosaurus laticaudus got to about 15 metres, although as the remains lacked a preserved crest the generic assignment is uncertain.

        Well I’m not aware of that one. What I would say is that having been femur measuring, there is nothing in the ODP database that is even close to these. The *smallest* femur I’ve measured in the collections here is about 20 cm longer than the *biggest* one recorded in the ODP. Of course that doesn’t rule out huge hadrosaurs with no femora, but it does show how these things are in terms of size.

    Holy crap, that’s a sauropod-sized hadrosaur…

    Isn’t there a lambeosaur from California based on a femur that’s really effing huge, too?

      Yeah, that would be the aforementioned Lambeosaurus laticaudus. Having looked about on the net, the description is here:

        Well there he’s talking about a 15m hadrosaur based on a 1.3 m femur. I’m talking femora in the region of 1.7 m and above. So rergardless of the scaling factor you use (length, weight, regressions, whatever),this is much, much, much bigger.

    I’ve read in some chinese website that the largest Zhucheng hadrosaur was over 20+ m….is this an exaggeration, or are there really specimens which could have reached that size?

    • 9 David Hone 06/07/2011 at 3:09 pm

      Well I’ve not looked at the scaling issue properly (yet). I guess my statement would be that I’m not aware of any calculations that show they could get that big, but equally, I wouldn’t be surprised if they did.

    I have a question that requires an answer, Can you list the hadrosaur species that lived in China alongside Shantungosaurus? I know some but for some reason there isn’t good articles on this subject here in U.S.

    Sorry to revive a dead horse, but can you divulge the lenght of the largest femora you measured? I am just trying to determine wether the 18.7 meter estimates for Huaxiaosaurus/Shantungosaurus are feasible.

    • 12 David Hone 07/05/2013 at 8:16 am

      Sorry, don’t have the data immediately to hand. However I would say a) they are really, really massive and that size is plausible, however, b) see my recent paper (and blog posts) on tail lengths. Total length as a measure of size is almost meaningless because tail length can vary so much.
