For decades, the tiny bones of a baby Apatosaurus remained tucked away in a museum drawer.

Bigger bones commanded the attention of scientists at the Sam Noble Oklahoma Museum of Natural History: The world's largest Apatosaurus, for one, which today dominates “The Clash of the Titans,” the centerpiece exhibit in the museum's Hall of Ancient Life.

But now it's the baby's turn. The world's smallest Apatosaurus, assembled from fossils collected more than 70 years ago, will be unveiled to the public Saturday.

The young dinosaur will stand next to the full-size adult Apatosaurus in “The Clash of the Titans” exhibit.
