Rib cage

For other uses, see human rib cage.

The rib cage of a cast of the "Wankel T. rex", a 90% complete Tyrannosaurus skeleton found by Kathy Wankel in eastern Montana in 1988. The cast of the skeleton is in the collection of the University of California Museum of Paleontology and on display at the Valley Life Sciences Building on the UC Berkeley campus in Berkeley, California.

The rib cage is an arrangement of bones in the thorax of animals. It is formed by the vertebral column, ribs and sternum and encloses the heart and lungs.
