No, it’s not our weekly sales meeting---today's fossil fuel is a pair of Harlan’s Ground Sloths (Paramylodon harlani), one of an extinct species of critter that lives on today in the form of modern sloths, anteaters and armadillos. These big boys grew up to 8 feet high, 17 feet long, and could tip the scales at upwards of 10,000 pounds. Unlike most mammals that migrated over the polar ice cap from Asia to North America, the sloths originated in modern-day Argentina during the Oligocene period (that’s, like, a long time ago) and migrated northward over thousands of years. While vulnerable to predators such as saber-tooth cats, they had a good long run in the New World---some may have actually held on until the 1500s in Cuba and the Caribbean, but they were extinct on the North American mainland by 8,000 BC. It’s been speculated, based on fossil finds, that some sloths may have actually been kept in pens by Paleolithic tribes as a food source. Given their combination of power and slow speed, we'd say these guys would likely be good for 5 tons each of quality diesel.
