This 27,000-year-old tooth of a giant ground sloth, which could reach over 13 feet tall during its lifetime, is like a climate time capsule
Fossil discoveries are exciting on their own, but sometimes, they carry even more information about the past. Newly uncovered fossils from an extinct giant ground sloth that lived in Belize 27,000 years ago provide a portrait of what the climate was like for the last year that the sloth was alive, according to a new study.
During the sloth's lifetime, Belize wasn't the jungle it is today. It was dry and barren. The Last Glacial Maximum had trapped most of Earth's water in glaciers and polar ice caps. The sea level and water tables were lower, and water was hard to find. The giant ground sloth, which could reach over 13 feet tall, was desperate for water. It found relief in a deep sinkhole, but it was never able to climb out.
