This is one of the strangest skulls; and yes, the animal really existed: Guanlong Wucaii.
The model is sculpted in blender and is divided into Skull and Jaw, already in the best printing position; Make sure to enable all supports!
Note: The jaw and the skulls don't have any way to attach one to another, however, if placed on a flat surface the skull will stay on top of the jaw (with mouth closed). If you plan on having it with the mouth open you will need some glue to make it stay in place.
The author marked this model as their own original creation.
