As several of you who have done lots of work in TresEd knows that all the dinosaurs in the official levels are made out of "mesh instances" where the dinosaur share the same mesh and physics as the basement version through the script. This allow the dinosaur to have its own unique script and behaviour without changing it for all other ones.
What the script don't do is change the mesh itself of the dinosaur, so while the dinosaur might look like the basement one, the mesh itself could be different. This can be seen on several dinosaurs:

What you can see here is that the mesh is actually from an earlier version of the dinosaur. The Albertasaur one can be found in build 96. The Para is the early one seen in build 96 IT. The Stegosaurus I have not found in earlier versions (but I have not looked closely). However, the t-rexes actually uses the early "Green T-Rex" mesh as their default one. Which means we kinda had the Green T-Rex mesh all these years but not the texture

I guess these could be related to the skeleton information machf talked about here: viewtopic.php?f=129&t=10937
While this doesn't give us much it can also tell us a bit about the development for the levels. For example this can tell us that the green T-rex was used in AS2 before they replaced it with the red one.
