Reed Gallery of the Age of Mammals
Level 2, Michael Lee-Chin Crystal
Turn around walk across the ramp, coming face to face with the T. rex. Turn left at the “Age of Mammals” to see the Giant Sloth inside the second display to your left.
The Giant Ground Sloth was a plant-eating mammal that lived in North and South America. Measuring up to 20 feet from head to tail, this extinct animal was much larger than any of its relatives today, which include armadillos, anteaters and tree sloths.
We really know our Ground Sloths! The ROM has the second best collection of real specimens in the world, and this is one of the few skeletons of its kind that you’ll see accurately mounted on all four legs. Most museums mount this species standing on its rear legs, reaching for a tree branch.
About the Gallery
This gallery displays more than 400 specimens found in both North and South America, representing the life and biodiversity from the Cenozoic Era (approximately 65 million years ago to the present day), including 30 fossil skeletons of extinct mammals.
