(Ben Miller, Field Museum)

“A big part of the Spinosaurus is that it's awesome. It's just this big, gnarly, cool dinosaur. That's why we have it at the entrance to the museum. We wanted to get people really pumped up and really excited about the natural world, not just today, but 95 million years ago when this thing was alive.”

The rare cast was built in Italy from

fossils found in the Sahara Desert

It’s propped up above the

ground and in a swimming pose

to evoke its reign as a

prehistoric river monster
