The American mastodon (Mammut americanum) was a large proboscidean that was a distant relative of the elephants (Elephantidae), but the mastodons were from an entirely different family (Mammutidae). They inhabited a large part of North and Central America from the Pliocene to the late Pleistocene, from Canada to Honduras. For this reason it has been questioned how woolly they would have been, because although in glacial regions such as Canada and the north of the United States it is quite probable and almost obvious that they were woolly to protect themselves from the cold, in regions such as southern Mexico to Honduras The climate even during the time was tropical, for which an animal weighing 6 tons and a robust body must have had problems with having abundant fur in a warm climate.
And although it is traditionally represented with hair (something valid for cold regions) it is because of a find found in New York that was considered mastodon hair, but they turned out to be algae.



El mastodonte americano (Mammut americanum) fue un gran proboscidio que era un lejano pariente de los elefantes (Elephantidae), pero los mastodontes eran de una familia totalmente diferente (Mammutidae). Habitaron una gran parte de Amйrica del Norte y Centroamйrica desde el Plioceno hasta finales del Pleistoceno, desde Canadб hasta Honduras. Por esto mismo se ha puesto en duda que tan lanudos habrнan sido, pues si bien en regiones glaciares como Canadб y norte de Estados Unidos es bastante probable y casi obvio que eran lanudos para protegerse del frнo, en regiones como el sur de Mйxico hasta Honduras el clima incluso durante la йpoca era tropical, por lo cual un animal de un peso de 6 toneladas y un cuerpo robusto debiу tener problemas de tener pelaje abundante en un clima cбlido.

Y si bien tradicionalmente se le representa con pelo (cosa vбlida para regiones frнas) es por un hallazgo encontrado en Nueva York que se consideraba pelo de mastodonte, pero resultaron ser algas.
