Traveling & Shipping

Hi Everyone, I'm relocating to Spain and I have some taxidermy that I'd love to keep, but I don't know if I'll be able to take any of these items with me. I have some small deer skull mounts, some small coyote skulls, small baby American gator skull, and a gemsbok skull and horns (the biggest thing I have). Is it possible to ship or bring any of this on a plane?
