The deep Amazon jungle of Brazil provides the backdrop for tales of the Mapinguari, a large nocturnal animal with a frightful screaming cry. Locals describe the Mapinguari as about two meters in height when standing on its hind legs. It is covered in red hair and emits a foul odor. Its feet are turned backwards and its claws are capable of ripping apart the palm trees upon which it feeds.

Ornithologist David Oren believes the Mapinguari is real. He has searched for it for twenty years. Oren suggests the Mapinguari is a surviving ground sloth, similar to the (presumably extinct) Mylodon . While the smaller tree sloths still exist, ground sloths are generally assumed to have died out around ten thousand years ago. So far no tangible evidence of the Mapinguari has survived close scrutiny.

Oren is not the first to suggest that giant ground sloths still exist. In the 1890s Ramon Lista, an Argentinian explorer, encountered a large unknown animal while hunting in Patagonia. Lista tried to shoot the animal but bullets apparently had no effect. Paleontologist Florentino Ameghino heard Lista's story. He was already familiar with descriptions of such a creature reported by Native Americans in Patagonia. They reported that arrows penetrated the creature's skin only with difficulty. Ameghino posited the creature might be a surviving ground sloth. Preserved skin samples from prehistoric ground sloths showed hard dermal ossicles that would have protected against prehistoric predators and, possibly, arrows and bullets as well. Ameghino named the purported modern ground sloth Meomylodon listai in Lista's honor.

Possibly the Mapinguari, if it exists, is not a giant ground sloth but an unknown large species of anteater. Anteaters and sloths are related animals. The well-known giant anteater Myrmecophaga tridactyla can reach a length of two meters and weigh nearly 40 kilograms. An anteater twice this size might be a candidate for Mapinguari.

Should the Mapinguari turn out to be a giant ground sloth it would not be the first such presumably extinct ice-age mammal to be found still alive in South America. In the early 1970s Ralph M. Wetzel and co-workers from the University of Connecticut discovered living specimens of the Chacoan Peccary, which he named Catagonus wagneri. Peccaries are close relatives of pigs and boars. Prior to Wetzel's find this type of peccary was known only from fossils and had been thought to have died out ten thousand years ago. Wetzel found the living specimens in Patagonia after hearing native stories. The natives called it the tagua. The Chacoan Peccary is the largest of the three known living species of peccary. There are significant differences in the chromosome numbers of the Chacoan peccary and the other two species, indicating they are not closely related. Very little is yet known of the Chacoan peccary's life cycle. It is considered to be an endangered species.

No. Sorry. So far the only info I have is this stub of an atticle on Wikipedia: http://en.wikipedia.org/wiki/Mapinguari But I'd estimate somewhere around 600, 700, 800 pounds.

this killing machine could be the key to saving the rainforest. Fight death with death/and/or fear.

sloth, slothfulness

a disinclination to work or exert yourself

Sounds alot like religion if you ask me...but my beef wasn't really with the idea that finding a creature like this would help to preserve the rainforrests...my beef was with the idea that something called a "sloth" would be a "horrifying killing machine that has been known( , I thought the creature was highly rare) to TWIST-OFF THE HEADS OF HUMANS???!!!".........Good freakin grief.

I'm sorry but does this really look like a killing machine?

I found this in one of the links that RachelM provided(thanks Rachel..good finds), where it describes this "creature" as..and I quote.."horrifying creatures he(a gentleman named David Oren..a scientist) knows are out there--huge sloths with giant claws and a reputation for twisting-off the heads of humans(TWISTING-OFF FOR GOD'S SAKE!!)--he could save he worlds largest rain forest"

Now.....forgive me if I err....but wouldn't the very WORD sloth and the idea of TWISTING-OFF HEADS be just a BIT of a contradiction in terms?
