"Molding, casting, and assembling a 50-foot whale is a puzzler's dream--- or nightmare," says head restorer William Sanders of the University of Michigan Museum of Paleontology. His team spent a year making casts of a Basilosaurus's fossil bones, shown here with ribs in the foreground, vertebrae behind. The white casts will be painted to match the rust-hued originals. The complete whale will look like the skeleton on pages 134-5.
