Introduction to Megafauna

The term 'megafauna' describes large animals that roamed Earth during the Ice Age. These creatures, often mammoth-sized, thrived in cold environments until their mysterious extinction.

Woolly mammoths were emblematic Ice Age giants, adapted to the cold with thick fur and humps of fat. Surprisingly, some isolated populations survived until just 4,000 years ago.

Saber-toothed cats, like Smilodon, had elongated canine teeth for hunting. Their social behavior and hunting tactics are still subjects of fascinating paleontological research and debate.

Glyptodons, armadillo-like creatures, bore a bony shell and weighed as much as a small car. They were actually distant relatives to modern armadillos, a surprising lineage connection.

Ice Age megafauna coexisted with early humans. This relationship played a significant role in the megafauna's extinction, with evidence of hunting and habitat changes.

The end of the Ice Age brought significant climate change, which altered habitats drastically. This, coupled with human activity, likely contributed to the mass extinction of these colossal species.

Recent DNA analysis has shed light on the extinction timelines of megafauna, revealing a more complex picture. This includes differing regional extinction patterns and the role of ecological niches.
