Does a Species of Giant Ground Sloth still exist in the Amazon Rain Forest?

I’m not impressed with the science credentials and logic of most cryptozoologists such as Loren Coleman.  Bigfoot is a man in an ape suit.  The famous film footage shot in the 1960’s is not of some unknown species of ape, but rather of a Hollywood stuntman in an ape costume.  The stuntman, Bob Heironimus, took a lie detector test on a television talk show, and the test showed he was telling the truth when he confessed to being the man filmed in the ape costume.  Still, Bigfoot believers (like Christian fundamentalists who believe in a literal translation of the bible despite the facts) refuse to accept that the film is a fake.  There may be a great deal of wilderness left in the Pacific northwest but it’s not so remote that a population of a gigantic species of ape could survive undetected following expedition after expedition.  However, the same can’t be said for parts of the Amazon jungle where there are still whole Indian tribes yet to be contacted by Western civilization.

The Amazon rain forest is so vast  there is  a remote possiblity that a large mammal species unknown to science may still live here.  Photo from google images.

I’m skeptical that a large mammal is yet to be discovered here, but it’s much more plausible than the existence of Bigfoot in the Pacific northwest.  The locals description of an animal they refer to as Mapinguari sounds just like a 3-toed giant ground sloth.  They say it is large, has long arms, red fur, long claws, and leaves foot prints with 3 toes.  Pat Spain of the National Geographic Series, The Beastmaster, interviewed a man who even claims to have shot and killed one, and his description of the event is consistent with what one would expect from an encounter with a ground sloth.  The hunter reported that his gun shots to the body had no effect, but eventually he killed it with a shot to its head.  This makes sense (if it actually happened) because ground sloths had armor, like their close relatives the armadilloes, under thick fur that could perhaps protect them from bullets to the body.  Pat showed the hunter pictures of various mammals, and the hunter pointed out an illustration of a giant ground sloth as the animal he killed.  However, he didn’t save any part of the animal because supposedly it smelled horrific, making his story doubtful in my opinion.  A poor Indian would surely understand the value of an unusual animal, particularly the monetary reward he could get by selling it to science. 

Illustration of Harlan’s ground sloth from google images.  The creatures the natives in Brazil describe sounds like a mylodon type of giant ground sloth.  Harlan’s ground sloth was the species of mylodon sloth that lived during the Pleistocene in southeastern North America.  Without positive physical evidence I remain doubtful that it is still extant even in the Amazon rain forest.

If the locals are telling the truth though, some interesting characteristics of giant ground sloths have come to light that we could never gain from just their skeletal remains.  Apparently, giant ground sloths move together with herds of the vicious white lipped peccary.  Perhaps, they forage on the same plant species and mutually attack predators for the Indians claim the sloth is the peccary’s protector.  Fruits and leaves brought down by the sloths when they tear trees apart may be a convenient source of food for the peccaries as well.  The sloths also have an odor that is said to be incapacitating, making for an additional defense mechanism besides their size, armor, and claws.  If it exists, it is probably a mylodon species of sloth related to Harlan’s ground sloth which used to inhabit southeastern North America during the Pleistocene.

Pat suggested stories among the natives of the Mapinguari may be legends passed down from actual encounters their ancestors made with this animal thousands of years ago.  The native people living in this region have had a continued existence here for thousands of years, and perhaps this animal only became extinct 2-3 thousand years ago rather than 11 thousand as science assumed. (See my blog entry entitled “CSI: Pleistocene Alaska.”)  And in fact, scientists know that dwarf ground sloths living on Carribean Islands survived until at least 4 thousand years ago, becoming extinct shortly after human colonization.

New recent discoveries of mammal species in South America would not be unprecedented.  Scientists found a population of Chacoan peccaries (Catagonus wagneri), a species thought to be extinct for 10 thousand years, in 1970, though the local natives had been hunting them for millenia and reporting about it to Westerners for years.  In the past decade scientists have discovered 10 new species of monkeys in the Amazon.  Maybe that’s why a real scientist, ornithologist David Oren, risked his reputation searching for this possibly extant species of ground sloth.  If it exists, it is likely in grave danger of extinction because natives from uncontacted Indian tribes still probably hunt them with no restrictions.

A review of The Beastmaster (National Geographic Channel Fridays 9:00 pm)

I like Pat Spain, host of The Beastmaster, because he’s a real scientist (a marine biologist) who seeks rational explanations first before succumbing to the possibility that a reported creature is an animal unknown to science.  On one episode for example he traveled to the Congo to investigate reports that a dinosaur-like creature inhabited a remote jungle.  He showed  pictures to the natives of various large animals, including those of long-necked sauropods.  The natives identified a sauropod as the creature called Mkobe Mkembe.  But Pat demonstrated that an elephant swimming across a deep river with only its head and trunk showing, closely resembled a sauropod, the trunk looking very much like a long neck, the head having the appearance of an animal’s upper body. 

On another episode Pat investigated reports of sea serpents off the coast of British Columbia.  He suggested a rare fish knowns as an oarfish, Agrostytichthys (sp.), may be the sea serpent of myth.

Pat leaves the door slightly open  for the possibility that a giant species of ground sloth still roams a remote region of the Amazon.

Pat’s great uncle was Charles Fort, the founder of Cryptozoology and the study of all unnatural phenomena, but the host of The Beastmaster says that he became interested in strange creatures long before he knew he was related to Fort.

    I’d love to believe that the Mapinguari that could actually be a Giant Sloth is just thought to be extinct. It would be so awesome if Pat Spain himself could prove that the Giant Sloths still exist. 🙂

  2. Cesar P. Cucio II Says:

    If the giant sloth still exists, why hasn’t anyone have remains of them? I mean, some villagers from all over the world use or keep bone or fur of animals that they kill. And in this episode that I watched, as I remember, a villager said that he shot the so called animal and it died somewhere in the jungle. If the animal died, It couldn’t have gone that far, so the body, or bones, should be near the spot that the villager shot the animal. I know that there is also a possibility that other animals ate the body of the animal and scattered its bones all over the area but how come no one has any solid evidence that it still exist? If one animal is there, there’s bound to be more, at least some left. Villagers always say that they see the animal from time to time and they call it by a spirit’s name. How come? No one has seen them. Is there a possibility that the villagers mistake another animal that looked like the giant sloth? Could there be a possibility that there is a new species of a sloth-like creature that is roaming around the Amazon? More expeditions must be conducted.

    They reviewed the video about bigfoot and proved that it is impossible for it to be a human in a suit. The proportions are to different.

    • markgelbart Says:

      Who reviewed the video of bigfoot?

      No so-called “expert” could ever prove any such thing from looking at a video.

      Here are the facts about that video:

      A guy named Bob, a Hollywood stuntman, appeared on a television show and admitted he was the man in the ape suit. He passed a lie detector test on public tv, strongly suggesting his claim was not false.

      Be logical and have a more skeptical mind when you are watching the psuedo-science television shows they put on tv for ratings.

      • Todd Rose Says:

        I have experienced the bigfoot phenomena firsthand. Bigfoot is definitely not a hoax and is a real animal. It is most likely Gigantopithecus.

  6. Todd Rose Says:

    Scientific technology is catching up to bigfoot. Bigfoot is most definitely not just a guy in an ape suit or many cases of mistaken identity/imagination. The arrogance of mainstream scientists who dismiss bigfoot out right without thoroughly investigating the phenomena for themselves is appalling. Bigfoot will most likely be a scientifically accepted species within the next decade due to DNA testing much to the chagrin of mainstream scientist who claim bigfoot is just a hoax.

  7. Ezekiel Carsella Says:

    U need to read On the track of Unknown animals by Bernard Heuvelmans. Might open your mind more.

  8. Thomas Zaccone Says:

    In 1997, there was an account of a strange large hairy beast that walked on two feet, had a small head, long arms, stank badly and was shot at and apparently showed no effects.
    This was at the Sites farm in very rural Sussex County, New Jersey. The creature had a human like scream. Google it. Also, Google “tree sloth vocalizations”.

    You need to leave comments about Christians out of the article. It has nothing to do with it and can turn many people off.
