What does your research tell us about human interactions with giant ground sloths before their extinction? We know that the extinction of megafauna, in South America at least, was around 10,000 ...

Recent studies have supported the idea that human expansion at this time was responsible for the demise of other large megafauna, such as mammoths. Ground sloths rapidly went extinct around 15,000 ...

When did the last of the ground sloths disappear? The standard answer is “about 10,000 years ago”. That’s the oft-repeated cutoff date for when much of the world’s Ice Age megafauna ...

In a new study, researchers used statistical analysis to show climate change was the primary driver of the disappearance of North America's largest species, including mammoths and giant sloths.

Megafauna are large animals, like elephants, whales, and even humans. They are found worldwide, but many of them are now extinct due to human interference and climate change.

Ecological historian Tim Flannery describes the days of megafauna, when 13-ton elephants and shoulder-height armadillos clomped around among humans.

A cooling, drying climate turned sloths into giants – before humans potentially drove the huge animals to extinction. Today’s sloths are small, famously sluggish herbivores that move through ...

The study results may also help shed light on any role humans may have had in the extinction of giant ground sloths. This confrontation of hunters and hunted took place more than 11,700 years ago ...

Megafauna across the Americas mysteriously disappear from the fossil record toward the end of the last ice age. Scientists have long debated what may have happened and largely point to two ...

Because Texas has other sites with evidence of prehistoric humans and megafauna, ... Giant ground sloths like these went extinct some 11,000 years ago — near the end of the Ice Age — possibly ...

The Ice Age megafauna left tracks on these flats, as did the humans that hunted them. The tracks are remarkable in that they are only a few centimetres beneath the surface and yet have been ...

The megafauna, both the giant armadillos and giant sloths, must have "developed an absurd strength in their arms" to be able to cut through rock and tough sediments that even a pickaxe would ...
