Pottok the Losino, the Galician, the Landais, and the Monchino horses. Tests have revealed considerable genetic differences between populations in the Northern Basque Country and the Southern Basque Country, leading some to consider them separate breeds. Some claim the Pottok's origins derive from the horses on ancient cave paintings in the area and thus claim to descend from the Magdalenian horses of 14,000–7000 BC. Other link its origins to an influx of horses during the Bronze Age. However, neither of these theories has to date been scientifically verified.

Campolina retilineo or straight region of the nasal bones as in image presented below. In the new ideal, male nasal bones are prominent, retain the height of the earlier ideals but are now expected to generate a smooth 'curved and continuous' appearance (see The desired head shape of a Campolina). The ideal for the profile of the female head is more dynamic with a narrowing between the nasal bones to refine the lower face. The curvature of the nasal bones should appear to extend naturally from the intersection of the orbit and maxillary and lead gently into the muzzle. Both male
