What was the tallest extinct mammal ever?

Answer 1

The largest mammal that is ever known to have lived was Paraceratherium, also known as Indricotherium. This animal can be described as a large hornless rhino with an elongated neck and head relative to its body. Paraceratherium had a height of 5.5 m (18 ft), over 8 m (27 ft) in length without the tail, the ability to raise its head 7.5 m (25 ft) over the ground, and a skull length of 1.35 m (4.5 ft). In comparison, the largest land mammal today, the African Bush Elephant, has a height of only 3.5 m (11.5 ft). The tallest giraffes match the height of Paraceratherium, but it weighed 5-10 times more -- estimates range from 10 to 20 tons. Even though this mammal I just explained to you is over-all the largest mammal , the tallest was Megatherium, otherwise known as the Giant Ground Sloth, it stood 21 feet tall, and weighed 16 tons, it was the largest known ancestor of the Three-Toed Sloth.
