This blog is for people to post any sightings or enconters if the Mapinguari. The posts can be anonymous or can be posted using your account. Any ways I would love to hear them.

This comment was posted on the Mapinguari page. It was posted anonymously and is very useful. It gave a description on its appearance and its behaviour.

"I have actually seen the Mapinguari in the Amazon Rainforest about ten years ago. I wish to remain anonymous but I will say that it had neither one eye, nor a mouth on its stomach and was in fact what I believe to be a Megatherium as this article suggests. I am virtually certain that this creature has, akin to the coelocanth, survived extinction to wander the rainforests today. I can confirm that it did indeed give off a strong odour and had great strength. The Mapinguari attacked me (in a manner of speaking) and with one backhand swipe it sent me flying into a tree and ran off. I dragged myself to the hospital and when quizzed about the claw marks on my chest I replied I must have scraped myself on a tree. I will never go to the news with this story and beyond this wikia page, no-one has or will ever hear it, not even my wife. I hope I have been able to help."

A reply was later posted under it anonymously. 

I have also seen the Mapinguari in brazil and I was at least 20 years old when I saw this thing and I was with my 17 year old cousine in the forest walking around and further on in the trail we smelt this foul odor. then I asked my cousine "Do you smell that and he told me "Yeah I smell it" so then I told him "I will peak around the tree and the Mapinguari was eating something that I never thought that would be in brasil. It was a eagle. So my cousine screamed.

This is a quote I found that goes reallly well with this page-

“We know that 96% of this last great wilderness remains unexplored. We also know that 1/3 of all mammals declared extinct in recent centuries have been found to still exist.

Add this to what I've learned out here, and there's only one conclusion: although as yet there's no smoking gun we need to take David Oren's theory very seriously indeed.”

These are some important dates i found on the cryptid archives wiki-


In 1930, an explorer named Inocèncio was exploring in the Amazon with ten friends when he got separated from them, and ended up lost. Whilst he was sleeping in a tree that night, he heard a terrible noise, and a shadowy bipedal figure came through the trees. He shot at it, and it fled, leaving behind a trail of blood.


A 1937 report from central Brazil claimed a Mapinguari had gone on a three-week rampage, killing over 100 cows and ripping out the tongues from their carcasses.


In 1975, a mine worker named Mário Pereira de Souza claimed to have come face to face with a Mapinguari in a mining camp in Rio Jamauchim. He heard a screaming noise, and the animal charged at him.

circa 1980's

One group of Kanamarí Indians living in the Rio Juruá valley claimed to have raised two infant Mapinguaris on bananas and milk; after one or two years their stench became to much to bear, and they were released.


In September 1981, in Valeria, a woman named Lydia was at the edge of the forest near her house at night, when she was startled by by a howling noise. She fled to her father, Teofelo, who grabbed a gun and went to untie his cow. He saw the Mapinguari, and shot at it before fleeing back to his house. The next day, all of the villager's moved, and settled by the edge of the river[8].


Glenn Shepard Jr., an American ethnobiologist and anthropologist based in Manaus, said he was among the skeptics until 1997, when he was doing research about local wildlife among the Machiguenga people of the far western Amazon, in Peru. Tribal members all mentioned a fearsome slothlike creature that inhabited a hilly, forested area in their territory.

Dr. Shepard also said “the clincher that really blew me away” came when a member of the tribe remarked matter of factly that he had also seen a Mapinguari at the natural history museum in Lima. When Dr. Shepard checked, he realised that the museum has a display featuring a model of the giant ground sloth[9]

circa 1990's

Sometime in the late 1990's Dutch zoologist Marc van Roosmalen heard that a tribe along the river Rio Purus found Mapinguari footprints near their settlement, and moved their houses to the other side of the river out of fear.

circa 1993

70-year old Joao Batista Azevedo was working by a river when he heard a Mapinguari scream. It came out of the forest, but neglected to approach or attack him[10].



A different view of the sloth model identified as a Mapinguari by Geovaldo.

In 2004, a hunter named Geovaldo Karitiana was hunting wild pigs when he was attacked by a Mapinguari. He fired at it multiple times before loading his gun with a lead slug, and firing at the animals face. The Mapinguari stopped and screamed in pain, and the hunter escaped[11].

2008 Destination Truth investigation

Main article: Flying Dinosaur/Sloth Monster.

In a 2008 investigation for Destination TruthJosh Gates travelled to the Amazon to interview eyewitnesses, including Geovaldo. He and his team carried out a nighttime investigation, where they heard the snapping of trees, and found torn-apart palm trees. They also heard an animal call, which a former Los Angeles zookeeper was unable to identify.

2011 Beast Man investigation

Main article: Nightmare of the Amazon.

Pat Spain's 2011 investigation came up with evidence of the Mapinguari being a giant sloth. He blasted a call and got a respose; both calls sounded like deeper sloth shrieks. He interviewed Geovaldo, who identified the animal he saw as a giant sloth.

2011 Man V Monster investigation

Main article: Brazilian Bigfoot.

An investigation by Richard Terry found a large shape on the night-vision camera. The animal was unable to be identified.

Undated sightings

Around 1977, a colleague of Dr. David Oren encountered the Mapinguari. Oren himself has collected over ninety accounts of the animal[1].


A Bullyland Megatherium toy used by Oren to interrogate eyewitnesses.

At an unknown time prior to 1999, a native hunter named Manuel Vitorino Pinheiro dos Santos shot four peccaries before hearing the call of the Mapinguari. He fled to the river as the second call shook the trees themselves, and hid under the water. The calls became muffled as the animal seemed to move deeper into the jungle, but Manuel remained hiding for hours[2].

At some point, a man named Edinalo worked for an oil company putting pipelines through the Amazon. When he got off his boat onto dry land, he was attacked by a large, smelly, hairy animal which broke his jaw. Overwhelmed by the smell, he blacked out, and was later found by more people[3]. The encounter was so terrifying for him, he quit his job and refused to enter the forest again.

At some point, two men were driving in their car when the Mapinguari came out of the forest. They hid, and it spared them[4].

At some point, a native woman was gathering fruit near her house when she was disturbed by a Mapinguari. She fled back to her house[5].

At an unknown time, a native hunter was stalking peccaries when a Mapinguari emerged from the trees. The man fled[6].

At another time, a man was cooking dinner inside his hut when the entire straw roof was torn off. He fled outside, only to be attacked by a Mapinguari[7].
