I wouldn't consider myself an expert, but I was really into prehistoric creatures when I was little.

Losing limbs takes a long time, geologically speaking, and generally involves the limbs shrinking to uselessness first. Early whales still had stubs where rear flippers used to be; heck, there are snakes around today that have bony spurs where their hind legs used to be as lizards. Given... I don't know... 20-30 million years, the T-Rex's descendants may have lost it's arms altogether.

And some limbs don't actually need to be connected to the main skeleton; most modern-day whales don't.

As for our Creature of Grimm... It isn't very dinosaur-like, I think. Its neck lacks the distinctive S-curve of most carnivorous dinos, more closely resembling reptiles that are confused for dinosaurs, like Dimetrodon. It has essentially no body, just a tail, neck, head and legs. Speaking of the legs, they jut far way from the body; I can't think of any straight-legged animals that have legs like that - legs that aren't placed mostly under the body to support it's weight.
