This is a 1/20th scale model of Apatosaurus excelsus rendered in polymer clay, and cast in polyurethane resin.

This model was constructed to be used in the study of the mass of Apatosaurus and other large fossil animals. It has been used to test several methods of estimating mass.

The paint work was done by Martin Garratt.

Very nice work. The detail is superb! Though the model looks a bit emaciated... at least in the upper part of the torso.
Why is that part so thin and bony compared to the rest of the body (I know this is "lean condition" but it seems far leaner than normal in THAT section alone)

Very nice. the texture of the hide and the colors chosen bring it to life! I like the proto bird taking off!

Apatosaurus and Brontosaurus are the exact same thing.

Quite true. In fact, there are several species of Apatosaurus, and this one (A. excelsus) was the species that was originally named Brontosaurus. It was later found that this species was not different enough to warrant a different name, and since Apatosaurus was named first, that name was accepted.

It looks great, but his legs look a lot like the forelegs of the brachiosaurus. Shouldn't they be stalkier like a brontosaurus? Or am I just an idiot?

You're not an idiot at all. In fact, the forelimbs should look a lot like those of Brachiosaurus because sauropod dinosaurs are actually quite conservative in the form of their limbs. Apparently, this form is rather efficient for supporting large masses. The primary difference between dinosaurs like Apatosaurus and Brachiosaurus will be in the ratio of length of forelimbs to hindlimbs. That is, brachiosaurs have forelimbs that are longer than their hindlimbs, while diplodocids like Apatosaurus have forelimbs that are roughly the same length as their hindlimbs. The heavier limbs that you see in other models of Apatosaurus are simply over-estimates of the size of the limbs.
