A dinosaur fossil that took 7,000 hours to prepare is finally open to the public.
The nodosaur was discovered in a Canadian sand mine in 2011.
It's skin and body armor are almost perfectly intact and show exactly what the nodosaur looked like.
The specimen is about 110 million years old and weights 2,500 pounds.
Experts say they think this nodosaur was swept out to sea by a flooded river. Minerals eventually took the place of its armor and skin, preserving its body shape.
The nodosaur is on display in Canada.
