What is the relationship between a mustang horse and a skull?

The relationship between a mustang horse and a skull primarily lies in the anatomical structure of the horse itself. A mustang, like all horses, has a skull that protects its brain and supports facial features. Additionally, skulls can be studied in Paleontology and Archaeology to understand the evolution and domestication of equine species. In art and culture, the juxtaposition of a mustang and a skull may evoke themes of freedom, life, and mortality.
