context_page_description: Primitive markings are a group of hair coat markings and qualities seen in several equine species, including horses, donkeys, and asses. In horses, they are associated with primitive breeds, though not limited to such breeds. The markings are particularly associated with the dun coat color family. All dun and non-dun 1 horses possess at least the dorsal stripe, but the presence of the other primitive markings varies. Other common markings may include horizontal striping on the legs, transverse striping across the shoulders, and lighter guard hairs along the edges of a dark mane and tail.
context_section_description: Less common primitive markings include vertically oriented markings which may be arranged as bars, fine striping, or smudges. Such markings include:
  Dorsal barbs are suggestions of vertical striping on either side of the dorsal stripe. They may be so closely placed that they resemble secondary dorsal stripes. Dorsal barbs are also called fishboning.
  Rib marks are extended, perhaps interrupted dorsal barbs. They are usually fine, faint stripes and may be responsible for some horses classified as brindle.
  A ventral stripe runs along the midline of the underbelly of the horse. They are usually wide and are uncommon.
  Zippers are lines of paler hairs running vertically along the back of the animal's leg, usually from the hoof to the knee. Because they consist of paler hairs and are found where horses often have feathering, zippers are considered by some to be guard hairs.
  Bider markings are only known in Przewalski's horses and native Mongolian horses from nearby. The bider is mostly symmetrical and found near the front of each shoulder, near the chest. The size of the bider ranges from a small dark spot to a large, webbed cape of darker skin and hair.
