Regarding Tarbosaurus have you seen this?

EDIT: I see this was already posted. Sorry about that.

No problem, I'd like to find out where the 14 yr old specimen is from and some more images of it's reconstruction.  Unless it's just a hypothetical in-between.

I'm really thinking hard on the Gorgosaurus..anyone have good skeletal images of adult/ sub-adult/ and juvenile ?   I actually have a replica of a 1/1 juvenile Gorgo Skull I can use for that part ..but it would be nice to see how it relates scale wise to the rest of the animal.

 A friend here let me know about this one form the T-Rex growth series exhibit at the Natural History Museum of Los Angeles County :



young adult Tyrannosaurus rex nicknamed Thomas after the discoverer's brother (34 feet, and approximately 17 years old) joined by a 20-foot juvenile (approximately 14 years old) and an 11-foot baby (2 years old). The growth series is a fascinating look at the ways that T- rex specimens grew, a process that included incredible growth spurts and body changes. After hatching as a 2-foot, 6-pound baby, for example, a T. rex could reach 30 to 35 feet (10,000 to 12,000 pounds) in less than two decades.

I'm particularly interested in the 20' juvenile..anyone have other info on it ?

To prove that I'm not wasting time here..lol  I sketched out the juvenile Gorgosaurus skull I have :



So I guess I'm doing a Gorgosaurus. I would like to find some skeletal diagrams though to work from.

Here's a diagram by GSP.  From top to bottom: Gorgosaurus, Albertosaurus, Tyrannosaurus, & Tarbosaurus.


And a Scott Hartman reconstruction.

Awesome ! Thanks, I'll be going with the subadult specimen of Gorgosaurus.  Looks like I need to modify my head a bit before cutting out.
