A.  aOrigin of the pantaneiro horse in Brasil.  c1992  aThe first horses that arrived in the Pantanal, a flooded land of the states of Mato Grosso and Mato Grosso do Sul (Central Western region of Brazil), formed a breed - the Pantaneiro horse - a product of the natural selection over the last three centuries, and adapted to the regional environmental conditions. Until recently, little or no human interference was imposed on this process. There is some information about dates when the first horses entered the region, but none of it is precise. The earliest origin appears to be related to such Spanish expeditions, as those of Pedro de Mendoza, in 1534; Alvar Nunez Cabeza de Vaca, in 1540; and Nuflo de Chavez, in 1543.  The animals brought by these expeditions were, for the most part, of Iberian horses. Some horses on these expeditions were lost in the Pantanal, proliferating and, consequently, populating the area. The "Guaicuru" indians helped to spred horses in the Pantanal. They learned horse management from the spanish and extended their range. Explorers arriving in the state of Mato Grosso, particularly in the 17th and 18th centuries, coming from the state of Sao Paulo, by way of the Tiete-Parana-Paraguay rivers, and from Goias, by road, may have also contributed to the introduction of horses into the region. Since the formation of the Pantaneiro breed, this horse in played an important role in the development of the Pantanal region.  aBrazil  aPantanal  aEqüino  aCavalo Pantaneiro  aEquine  aHorse pantaneiro  aOrigem  aOrigin1 aSERENO, J.
