Mapinguari, or mapinguary (also called the juma), are mythical monstrous jungle-dwelling spirits from Brazilian folklore, said to protect the Amazon rainforest and its animals.
Mapinguari, or mapinguary (also called the juma), are mythical monstrous jungle-dwelling spirits from Brazilian folklore, said to protect the Amazon rainforest and its animals.
There are various depictions of the mapinguari. Prior to 1933, traditional folklore describe it as a former human shaman turned into a hairy humanoid cyclops. [1] This version is often said to have a gaping mouth on its abdomen, [2] with its feet turned backwards. Creatures with such feet, which confuse those trying to track it, are found in folklore around the world. [1]
In the latter half of the 20th century, some cryptozoologists speculated that the mapinguari might be an unknown primate, akin to Bigfoot. [1]
Others claim that it is a modern-day sighting of a giant ground sloth, an animal estimated to have gone extinct at the end of the Late Pleistocene. [2] [3] These later descriptions may be attributed to David C. Oren, an ornithologist, who heard stories of the creature and hypothesized they might be the extinct sloths. This was met by criticism by scientists at the time, but an article Oren published in 1993 was picked up by major news papers despite no evidence. [1] Skeptics point out that there have not been any fossil records of ground sloths for thousands of years. [4]
A 2023 academic study of the 1995 discovery of giant sloth bones “modified into primordial pendants” suggested that humans lived in the Americas contemporaneously with the giant sloth, specifically that “it may have served as inspiration for the Mapinguari, a mythical beast that, in Amazonian legend, had the nasty habit of twisting off the heads of humans and devouring them.” [5]
According to Felipe Ferreira Vander Velden, its name is a combination of the Tupi-Guarani words "mbappé", "pi", and "guari", meaning "a thing that has a bent [or] crooked foot [or] paw". [6] Other names by which they are referred to include the Karitiana kida harara, [6] and the Machiguenga segamai. [2] [3]
A reference to Mapinguari occurs in the 2020 animated film The Red Scroll , during the final scene when the character Wupa transforms into a giant sloth monster. [7]
Ground sloths are a diverse group of extinct sloths in the mammalian superorder Xenarthra. They varied widely in size with the largest, belonging to genera Lestodon, Eremotherium and Megatherium, being around the size of elephants. Ground sloths represent a paraphyletic group, as living tree sloths are thought to have evolved from ground sloth ancestors.
Folk memory, also known as folklore or myths, refers to past events that have been passed orally from generation to generation. The events described by the memories may date back hundreds, thousands, or even tens of thousands of years and often have a local significance. They may explain physical features in the local environment, provide reasons for cultural traditions or give etymologies for the names of local places.
The term Australian megafauna refers to the megafauna in Australia during the Pleistocene Epoch. Most of these species became extinct during the latter half of the Pleistocene, and the roles of human and climatic factors in their extinction are contested.
Archaeoindris fontoynontii is an extinct giant lemur and the largest primate known to have evolved on Madagascar, comparable in size to a male gorilla. It belonged to a family of extinct lemurs known as "sloth lemurs" (Palaeopropithecidae) and, because of its extremely large size, it has been compared to the ground sloths that once roamed North and South America. It was most closely related to Palaeopropithecus, the second largest type of sloth lemur. Along with the other sloth lemurs, Archaeoindris was related to the living indri, sifakas, and woolly lemurs, as well as the recently extinct monkey lemurs (Archaeolemuridae). The genus, Archaeoindris, translates to "ancient indri-like lemur", even though it probably became extinct recently, around 350 BCE.
Palaeopropithecus is a recently extinct genus of large sloth lemurs from Madagascar related to living lemur species found there today. Three species are known, Palaeopropithecus ingens, P. maximus, and P. kelyus. Radiocarbon dates indicate that they may have survived until around 1300–1620 CE. Malagasy legends of the tretretretre or tratratratra are thought to refer to P. ingens.
Megalonyx is an extinct genus of ground sloths of the family Megalonychidae, native to North America. It evolved during the Pliocene Epoch and became extinct at the end of the Late Pleistocene, living from ~5 million to ~13,000 years ago. The type species, M. jeffersonii, the youngest and largest known species, measured about 3 meters (9.8 ft) in length and weighed up to 1,000 kilograms (2,200 lb).
Brazilian mythology is a rich and diverse part of Brazilian folklore with cultural elements, comprising folk tales, traditions, characters, and beliefs. The category is representative of Brazil’s greater culture, being a melting pot of Iberic traditions brought by the Portuguese settlers, African traditions brought by Africans during the colonial slave trade, and the traditions and stories of indigenous groups that have occupied Brazil for centuries.
Karitiana, otherwise known as Caritiana or Yjxa, is a Tupian language spoken in the State of Rondônia, Brazil, by 210 out of 320 Karitiana people, or 400 according to Cláudio Karitiana, in the Karitiana reserve 95 kilometres south of Porto Velho. The language belongs to the Arikém language family from the Tupi stock. It is the only surviving language in the family after the other two members, Kabixiâna and Arikém, became extinct.
Pleistocene rewilding is the advocacy of the reintroduction of extant Pleistocene megafauna, or the close ecological equivalents of extinct megafauna. It is an extension of the conservation practice of rewilding, which aims to restore functioning, self-sustaining ecosystems through practices that may include species reintroductions.
Melbourne Bone Bed is a paleontological site located at Crane Creek in Melbourne, in the U.S. state of Florida. This site contains fossils from the Late Pleistocene period 20,000 to 10,000 years before the present. The fossils include extinct animals such as varieties of camels, dire wolves, Florida cave bears, giant armadillos, giant beavers, giant bison, giant ground sloths, mammoths, mastodons, saber-toothed cats, and tapirs.
The Late Pleistocene to the beginning of the Holocene saw the extinction of the majority of the world's megafauna, which resulted in a collapse in faunal density and diversity across the globe. The extinctions during the Late Pleistocene are differentiated from previous extinctions by its extreme size bias towards large animals, and widespread absence of ecological succession to replace these extinct megafaunal species, and the regime shift of previously established faunal relationships and habitats as a consequence. The timing and severity of the extinctions varied by region and are thought to have been driven by varying combinations of human and climatic factors. Human impact on megafauna populations is thought to have been driven by hunting ("overkill"), as well as possibly environmental alteration. The relative importance of human vs climatic factors in the extinctions has been the subject of long-running controversy.
The sloth lemurs (Palaeopropithecidae) comprise an extinct family of lemurs that includes four genera. The common name can be misleading, as members of Palaeopropithecidae were not closely related to sloths. This clade has been dubbed the ‘‘sloth lemurs’’ because of remarkable postcranial convergences with South American sloths. Despite postcranial similarities, the hands and feet show significant differences. Sloths possess long, curved claws, while sloth lemurs have short, flat nails on their distal phalanges like most primates.
Archaeolemur is an extinct genus of subfossil lemurs known from the Quaternary of Madagascar. Archaeolemur is one of the most common and well-known of the extinct giant lemurs as hundreds of its bones have been discovered in fossil deposits across the island. It was larger than any extant lemur, with a body mass of approximately 18.2–26.5 kg (40–58 lb), and is commonly reconstructed as the most frugivorous and terrestrial of the fossil Malagasy primates. Colloquially known as a "monkey lemur," Archaeolemur has often been compared with anthropoids, specifically the cercopithecines, due to various morphological convergences. In fact, it was even misidentified as a monkey when remains were first discovered. Following human arrival to Madagascar just over 2000 years ago, many of the island’s megafauna went extinct, including the giant lemurs. Radiocarbon dating indicates that Archaeolemur survived on Madagascar until at least 1040-1290 AD, outliving most other subfossil lemurs.
Subfossil lemurs are lemurs from Madagascar that are represented by recent (subfossil) remains dating from nearly 26,000 years ago to approximately 560 years ago. They include both extant and extinct species, although the term more frequently refers to the extinct giant lemurs. The diversity of subfossil lemur communities was greater than that of present-day lemur communities, ranging to as high as 20 or more species per location, compared with 10 to 12 species today. Extinct species are estimated to have ranged in size from slightly over 10 kg (22 lb) to roughly 160 kg (350 lb). Even the subfossil remains of living species are larger and more robust than the skeletal remains of modern specimens. The subfossil sites found around most of the island demonstrate that most giant lemurs had wide distributions and that ranges of living species have contracted significantly since the arrival of humans.
Gypsum Cave is a limestone cave in eastern Clark County, Nevada, United States, about 15 miles (24 km) east of Las Vegas, that is listed on the National Register of Historic Places (NRHP).
Paul Schultz Martin was an American geoscientist at the University of Arizona who developed the theory that the Pleistocene extinction of large mammals worldwide was caused by overhunting by humans. Martin's work bridged the fields of ecology, anthropology, geosciences, and paleontology.
Paleontology in Nebraska refers to paleontological research occurring within or conducted by people from the U.S. state of Nebraska. Nebraska is world-famous as a source of fossils. During the early Paleozoic, Nebraska was covered by a shallow sea that was probably home to creatures like brachiopods, corals, and trilobites. During the Carboniferous, a swampy system of river deltas expanded westward across the state. During the Permian period, the state continued to be mostly dry land. The Triassic and Jurassic are missing from the local rock record, but evidence suggests that during the Cretaceous the state was covered by the Western Interior Seaway, where ammonites, fish, sea turtles, and plesiosaurs swam. The coasts of this sea were home to flowers and dinosaurs. During the early Cenozoic, the sea withdrew and the state was home to mammals like camels and rhinoceros. Ice Age Nebraska was subject to glacial activity and home to creatures like the giant bear Arctodus, horses, mammoths, mastodon, shovel-tusked proboscideans, and Saber-toothed cats. Local Native Americans devised mythical explanations for fossils like attributing them to water monsters killed by their enemies, the thunderbirds. After formally trained scientists began investigating local fossils, major finds like the Agate Springs mammal bone beds occurred. The Pleistocene mammoths Mammuthus primigenius, Mammuthus columbi, and Mammuthus imperator are the Nebraska state fossils.
De-extinction is the process of generating an organism that either resembles or is an extinct species. There are several ways to carry out the process of de-extinction. Cloning is the most widely proposed method, although genome editing and selective breeding have also been considered. Similar techniques have been applied to certain endangered species, in hopes to boost their genetic diversity. The only method of the three that would provide an animal with the same genetic identity is cloning. There are benefits and drawbacks to the process of de-extinction ranging from technological advancements to ethical issues.
