Mastodons on the other hand had a low, long skull with small ears.Īnother significant distinguishing feature between the mammoth and the mastodon was their teeth. The mammoth had a high, peaked head and large ears. At five to eight tons, and only 2.3 to 2.8 meters at the shoulder, mastodons weighed less and were shorter. Mammoths had sparse to woolly fur and a short tail, unlike the long, brown, shaggy fur of the long and hairy-tailed mastodons. Mastodons weighed between 5 to 8 tons and grew up to about 2.3 to 2.8 meters at the shoulder. Mammoths were heavier, weighing between 5.4 to 13 tons, with an adult height between 2.5 to four meters at the shoulder. This video on the exhibits of the Field Museum throws more light on the differences between these two giants of the ice age: Both were muscular, four-legged mammals with a trunk, curved tusks and a tail. Mammoths were a species of the extinct genus Mammuthus, while mastodons were a species of the extinct genus Mammut.
