Spanning an impressive 111 feet (34 meters) in width, 105 feet (32 m) in length, and standing 18 feet (5.5 m) tall, this colossal organism — so large it’s even visible even from space ...
Its tusks have been known to reach 2.7 m (9 ft) in length, although in modern populations they are most commonly recorded at a length of 0.6–0.9 m (2 ft 0 in – 2 ft 11 in). [1] The average walking speed of an elephant is 7.2 km/h (4.5 mph), but they can run at recorded speeds of up to 24 km/h (15 mph). [2]

The thallus of U. mammulata is usually 4 to 15 cm (1.6 to 5.9 in) in diameter, but specimens have been known to reach 63-centimetre (2.07 ft) in the Smoky Mountains of Tennessee. [ 34 ] The longest lichen is Usnea longissima , which may grow to exceed 20 feet (6.1 m) in length.
It was approximately 3 m (9.8 ft) long and 1.5 m (4.9 ft) tall, and is estimated to have weighed 1.5–2.5 tonnes. [125] Prior to the description of J. monesi, the largest known rodent species were from the genus Phoberomys, of which two species have been discovered.
