But did they really have such little arms? I don’t want to start a heated debate or anything, but I don’t believe evolution is physically possible. I was wondering if there are any explanations other than their being an intermediate species. Thanks 
I’m not sure if there has been anything new on Tyrannosaur arms so I might be wrong on this but from my understanding they didn’t have much uses for their arms because of their heads doing most of the work which is why they are so small, but if you think their arms are tiny you should have a look at Abelisauridae arms.
Fantastic work! I’m not really a fan of the color scheme because it reminds me of a giraffe but I love the rest of it. I have a question about the legs, aren’t they a little bit skinny from the front? I might be wrong on this but I thought theropods had skinny legs from the side but they were very wide from the front.
Thanks!
This could largely just be a perspective thing as there isn’t really a clear anterior view of the legs in any of the renders I’ve linked to. The overall proportions here are reasonable, and the hindlimbs of the model definitely are wider in anterior view, at least at the feet and distal shank. It’s certainly true that the actual long bones of the limbs are quite broad in anterior view - given that I constructed the model muscle-by-muscle on top of a real skeleton scan, I can confirm that. The thing about muscle reconstruction is that it is largely equivocal. We can infer the actual muscle attachment sites and general muscle pathways with relatively high confidence, but the actual 3D shapes and bulks of the muscles are going to be open to interpretation. The legs you see here are certainly on the slimmer, more conservative end of the spectrum of interpretation. That said, I wouldn’t be comfortable adding too much more muscle, especially around the shank. There are a few reconstructions out there that I feel difficult to justify when actually attempting to visualise how the muscles would work in 3D. However, there are definitely interpretations that differ from what you see here while still being as valid. That’s just the nature of the subject really.
Ah I see, thank you for clearing that up!
I’ve said this elsewhere but this is one of the best rex reconstructions out there.
