What heavily armored dinosaur fossils were found in Utah?

Scientists recently discovered two new species of heavily armored dinosaurs (or ankylosaurids) in Utah about 100 miles southwest of Salt Lake City. The species were both about 30 feet (9 meters) in length. One is an ankylosaur, or club-tailed armored dinosaur, and is the oldest ever found. The other fossil is that of a nodosaur, a clubless armored dinosaur, the largest on record. Most ankylosaurids were from Asia; these animals were thought to have crossed over a land bridge to North America about 100 million years ago.
