65 millions years old - found in Wyoming, USA. Museum National d’Histoire Naturelle, Paris, France.
3D scanned using Agisoft Photoscan.
Update : I uploaded a new version of the scan. More detail, better texture, and should be suitable for 3D Printing (no holes). You might notice the skull seems to have a weird shape : this is not a scanning issue, the skull was deformed during the fossilization process.
