Okay, kiddo, so a horse is a big animal with a head that has a skull inside. The skull is like a hard and bony helmet that protects the horse's brain.
The horse's skull has many interesting parts. The big round holes in the front are where the horse's eyes go. The long snout is where the horse's nose and mouth are. And the teeth inside the skull help the horse chew its food.
Sometimes people study horse skulls to learn more about horses. They might look at the size and shape of the skull to figure out what kind of horse it was. They might also use the skull to learn more about how horses eat, breathe, and move.
Overall, horse skulls might seem a bit spooky, but they are important tools for learning and understanding these majestic animals.
