The life-sized model of an Indricotherium is without question the star of the Extreme Mammals exhibition which opened on June 3, 2011, at the Canadian Museum of Nature.
This herbivorous animal was about five metres tall and weighed as much as 18 tonnes. It lived in the forests of Central Asia between 34 and 23 million years ago. (Read more about Indricotherium on the American Museum of Natural History (AMNH) web site).
The model is much taller than the doorways of our galleries and it travelled in pieces. See photos of its assembly at the Canadian Museum of Nature.
The first photos show how the pieces of the model are assembled by the teams from the Canadian Museum of Nature and AMNH. You can see the immense height of the Indricotherium.

A local model-maker, Ronald Seguin, did the finishing work. He used expanding foam during this work. He uses it to smooth places where the pieces join together, sculpting it to make it blend in.
Using a piece of fabric, Ron applies a thick, coloured coating to mimic the skin texture. Finally, he finishes with two more coats in different colours to match the model’s appearance.

Et voilà! The Indricotherium is ready to welcome visitors to the entrance of the exhibition.

Extreme Mammals is organized by the American Museum of Natural History, New York, USA, in collaboration with the Canadian Museum of Nature, Ottawa, the California Academy of Sciences, San Francisco, USA, and the Cleveland Museum of Natural History, USA.











While visiting the exhibit and looking at the pictures, I have notice that their is no tail on the Indricotherium.
where did the tail go?
Hi Diane… I took some of the photos above including the one in which we can clearly see the tail. I will be visiting the exhibit this evening and I’ll take a look to see if the tail is in its proper place. Thanks for your comment.
Diane,
I have found out why there is no tail… The full Indricotherium is a bit too tall for the ceilings at the Museum of Nature. There is an additional piece that goes on top of the Indricotherium, but it had to be removed in order to make the exhibit fit into the gallery. The tail is part of that upper piece that needed to be left off. Our exhibitors did try to place the tail onto the lower part of the body, as you see in the photos above, but in the end it was decided that the tail did not look “right” without the top piece and so the decision was made to remove it. Thanks for your comment.
It’s been many years now, since working with Ron Seguin..way back in the 80′s, where he taught me how to cast dinosaur bones along with the shark we plastered in the basement off of Cornation Road. in Ottawa. He just kept getting better and better! So thrilled to see this magnificent installment at the Museum of Nature!
