Here is a museum quality Tyrannosaurus-rex skull model. It's a scan from a real skull which has been repaired. It come in two parts, top and bottom jaws so you can open the mouth. The model has lots of maps, color, normal, displace, occlusion, specular and bump. All of them are 8k maps. This is probably the more realistic and accurate T-Rex skull you'll find around here. It comes in several formats, 3dsmax (.max), maya (.mb), alembic and obj so you should be able to open the file easily. Enjoy, Julien.
