Scientists found amazing dinosaur bones in Utah! The dig site is near Arches National Park. The bones could be 140 million years old. That is a very, very long time ago! This is a super exciting discovery.

The place is called the Ironstone Bonebed. The rocks there are red like rust. Scientists think they found a new dinosaur! It was an armored dinosaur with bony plates. These plates kept the dinosaur safe.

Two scientists worked together for 25 years. They are digging up the bones now. The fossils can teach us about old animals. Scientists will study the bones for a long time. This discovery is really cool!
