Macrauchenia ("long llama ", based on the now-invalid llama genus, Auchenia, from Greek "big neck") is an extinct genus of large ungulate native to South America from the Pliocene [1] or Middle Pleistocene to the end of the Late Pleistocene. [2] .

2017年6月27日 · An odd extinct mammal that lived in South America during the last ice age had a long neck like a llama's, three-toed feet like a rhino's and what may have been a tapir-like trunk.

2022年10月13日 · Macrauchenia disappeared from fossil records during the late Pleistocene between 20,000 to 10,000 years ago. It isn’t clear what led to the disappearance of this genus. However, considering the fact that they lived during the ice age at a time of dramatic climatic changes, changing weather conditions could have contributed to their disappearance.

2017年6月27日 · Macrauchenia patachonica lived during the last ice age. It resembled a bulky camel without a hump, with a long neck like that of a llama and a short trunk for a nose.

2017年6月29日 · Now, a new study has used DNA to solve the riddle of where in the evolutionary tree the enigmatic Macrauchenia patachonica belongs, The Washington Post reports. Researchers analyzed mitochondrial DNA from a Macrauchenia fossil and found that the animal is closely related to a group of ungulates that includes horses, rhinos, and tapirs .

Macrauchenia is the scientific name for an extinct plant-eating mammal from South America, belonging to an extinct group of mammals called the litopterns. The best-known species is M. patachonica. In 2015, fragments of collagen were extracted from its bones and showed that its closest living relatives are the perissodactyls - horses, rhinos and ...

2017年7月3日 · Macrauchenia were herbivores that roamed open, grassy spaces across South America before disappearing with many other megafauna at the end of the last ice age, around 12,000 years ago.

In the mobile game Ice Age Village, the Macrauchenia is referred to as "sneaky mammal". These Macrauchenia are similar in appearance to the hornless rhinoceros Indricotherium/Paraceratherium, as both of them have long necks, thick legs, small heads and tower over most other creatures.

2023年1月23日 · Based on the fossils discovered of these species, we know that Macrauchenia resided in what is modern-day South America. They existed there until about 11,000 years ago, which was roughly the end of the Pleistocene epoch. The Pleistocene epoch was the last Ice Age, which began around 2.5 million years ago and ended 11,700 years ago.

2021年4月25日 · For the first time, scientists have recovered ancient DNA from one of the more puzzling species to have lived during the last Ice Age, a creature named Macrauchenia patachonica. The DNA allows researchers to finally map the mammal’s relationships and place it within a group that includes horses, rhinos, and tapirs.
