I read the boxcar children Dinosaur Mystery written by Gertrude Chandler Warner.

The Aldens are a group of siblings who went to live with their grandfather when their  parents died.

While the Aldens were helping to create an exhibit at the Natural History Museum, some one stole two dinosaur bones from the tail of a T.Rex.

At first the Aldens suspected Pete because he was a clumsy security guard always running into the wrong rooms.

The Aldens continued to work at the Museum and discovered that Dr. Pettibone had hidden two of the tail bones and the jaw bone to bring popularity to the Dino World exhibit with a plan replace them on the day when it was opening.

In the end, Benny Alden found the missing bones and replaced them just before the grand opening of the Dino World Exhibit.
