Which facial marking is described as a small, oval white marking on the forehead?

The facial marking described as a small, oval white marking on the forehead is known as a star. This characteristic marking is often found on certain breeds of horses and serves as a recognizable feature in equine identification. A star typically appears centered on the forehead, and its size and shape can vary, but its oval form is a defining characteristic. This marking can add uniqueness to a horse's appearance and can often be used in combination with other facial markings to provide a more specific identification of individual animals.

In contrast, other facial markings such as a snip, strip, and blaze have different characteristics and placements. A snip is typically a small white marking on the muzzle, often between the nostrils. A strip is a narrow white line that runs down the center of the face, and a blaze is a wider marking that often extends from the forehead down over the nose. Each marking serves its own purpose, but the definition of a star clearly aligns with the description provided.
