Gorgosaurus libratus by ScottHartman Gorgosaurus libratus by ScottHartman
Another one of my old 2004 era skeletals gets the 2012 update treatment. Gorgosaurus is a fairly gracile tyrannosaurid, but this was restored after sub-adult specimen TMP 91.36.500, which is even more gracile than adult specimens.

Would the arms and face really have that little muscle?

Experience seems to show that when I talk about dinosaurs I mostly say bullshit, but I have to ask anyway, at least to be corrected^^:

Some bipedal dinosaurs like this one remember me a little kangaroo skeleton, so, are some of them known to be able to sprint, jumping with joined feet like a kangaroo, or is it impossible for some reason?

By the way, Mr. Hartman your work is amazing. You are a titan!

Actually you're in good company, as some 19th century paleontologists also thought theropods (and ornithopods) looked like oversized kangaroos. There are some anatomical reasons why hopping isn't likely, but the best line of evidence is that there are many millions of bipedal tracks known from different times and places in the Mesozoic and not one of them shows a hopping gait.

I begin to ask myself if I’m not possessed by the spirit of a dead paleontologist -_-‘, first I draw a parasaurolophus breathing under water with a broken crest, then a sauropod with only the top of its head over the surface of a river, and now that… at least it allow me to understand better.

This it almost weird to me that no hopping theropods existed since a lot of small birds do it. Now I have to find when they began to move like this^^.

Thanks for your aware answer.

Is it okay if I use your skeletal as reference for a drawing?

Oh, and where it's appropriate I appreciate it when people can credit me for the anatomical basis :)

Yup, go ahead. If you get some major commercial job and want to base it on my work then drop me a line, but otherwise please have at!

Gorgosaurus libratus was certainly faster and more agile than potential competitor Daspletosaurus sp, although i know adult G. libratus would be a bit slower than sub-adults like TMP 91.36.500. It would be more effective at hunting fast moving dinosaurs. However i wouldn't say D. sp was primarily scavenger, because it wouldn't survive eating mostly dead bodies. Some people say Gorgosaurus hunted ceratopsians like Chasmosaurus, but wouldn't Daspletosaurus be better built for hunting this kind of prey? Also another question. Is there possible that Daspletosaurus could be fast enouth to hunt large hadrosaurs? Look at its feet and Brachylophosaurus's. [link]

You are right that this subadult specimen is longer-legged than larger adult specimens. Daspletosaurus would have been fast enough to catch hadrosaurs - their overall limb proportions are easily more cursorial than other large herbivorous dinosaurs in their environment.

And finally, there simply is no such thing as terrestrial carnivores that scavenge exclusively for a living.

Almost looks disproportionate. I guess puberty is awkward for dinosaurs too.

The original version was actually on my website, so you can always check there too if you don't see something here.

I was thinking of doing a Gorgosaurus drawing but I wasn't sure which prey animal would be best fitted for it. What do you think Gorgo was hunting since they were so gracile?

Ornithomimids and mid-sized hadrosaurs? The adults are a bit less gracile.

I thought gorgosaurus was bigger. Or is this a sub species of the normal gorgosaurus?

It's a sub-adult specimen.
