BUILDING THE PERFECT BEAST . . .

Mark Goodwin welding BUILDING a free-standing mount of a forty-foot skeleton wasn't easy. The skeleton had to fit inside a circular stairwell twenty feet across and had to be braced with an internal steel armature to guard against the earthquakes that northern California has been known to experience. It also had to be as biologically accurate as possible; an active pose was desired. A team of museum scientists, students and sculptors from Industrial Light and Magic fulfilled all of these conditions with flair.
 
What follows is a short "virtual slide show" to demonstrate how it was accomplished — click on any of the slides below for a closer look.

Unpacking the crate

The cast of the T. rex skeleton was shipped to us in a twelve-foot wooden crate. Of course, the first step in assembling the skeleton was unpacking all 300-odd bones, a task performed here with great aplomb by Principal Museum Scientist Mark Goodwin (left) and then Museum Director Dr. Jere Lipps (right).
 
Painting the bones

Each cast of each bone had to be washed, tooled, and painted by hand, a task done by UC undergraduate Tina Athena Trakadas (in this picture) and by the entire crew.
 
Welding the framework

The skeleton's pose was worked out in the laboratory with a model before actual construction began. Each cast of the fossil was then cut and drilled to accommodate an internal framework of steel tubing. This was fabricated in the workshop and then assembled in place.

Mounting the skull

Mark prepares to mount the skull. As bone after bone is added, the skeleton begins to take shape.
 
The skeleton attracts attention

Finished!

Hanging the Pteranodon

And there's more — over the head of Tyrannosaurus rex glides the skeleton of Pteranodon, a pterosaur or flying reptile. The Pteranodon was assembled in the preparation laboratory and is seen here as the crew prepares to hang it from the ceiling.
