LOS ANGELES (AP) - A trio of Tyrannosaurus rex skeletons is the main attraction in the new Dinosaur Hall at the Natural History Museum in Los Angeles.

The exhibit opens July 16.

The three T’s include an 11-foot-tall 2-year-old, the youngest known T fossil in the world.

A 20-foot-tall 13-year-old T weighed about 4,000 pounds when it died. Thomas is the oldest at 17 and was 34 feet long and weighed nearly 7,000 pounds. It is about 70 percent complete and has never been on exhibit before.

All three fossils were found in the badlands of Montana.

Three hundred fossils and 17 other dinosaur skeletons will be on display in the hall, which nearly doubles the museum’s dinosaur display space.

Admission ranges from $5 to $12. Members and children under 4 are free.
