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.

Answer 2

The tallest extinct mammal was the Paraceratherium, also known as Indricotherium. It stood about 18 feet tall at the shoulders and could reach up to 25 feet in height with its neck stretched out.
