  Restoring the Skeleton

In March 2010, the post-cranial bones of the Museum's Blue Whale skeleton were sent to Academy Studios in Novato, California for a thorough restoration. The original skull remained at the Museum because it was too badly deteriorated to be restored. The new skull and mandibles (jaw bones) of the Museum’s newly restored Blue Whale skeleton is from a similar-sized Blue Whale that stranded in Ventura, California in September 2007 (#SBMNH 2007-19). Below are pictures that show the restoration process of the post-cranial skeleton and the assembly of the new skull and mandibles to the skeleton.

Ribs stripped of old paint, bondo and fiberglass.

Forms used to make replicas of phalanges (finger bones) that are being replaced on the refurbished mount. Whales have individual digits on the inside of their flipper. 

Terminal caudal vertebrae (tail vertebrae) borrowed from Los Angeles County Museum of Natural History to make cast replicas for our refurbished Blue Whale skeleton.

Recently refurbished cervical vertebrae (neck vertebrae) for the Museum's Blue Whale skeleton.  Note the intervertebral disks that were modeled to fit in between each of these vertebrae.

Refurbished Blue Whale vertebrae with the first  primer coat of paint.  Note that the holes in these vertebrae have not yet been resized to fit the larger diameter of pipe that will be used to support the refurbished skeleton.
 

Drilling rig used to resize the holes in the vertebrae for the larger pipe that will be used on the refurbished skeleton.

Vertebrae drilled to larger pipe diameter. Note the notch cut at the base of the hole through the vertebrae. This notch will slide along a strip of steel welded to the pipe to keep the vertebrae from rotating on the pipe.

Vertebrae suspended on pipe supports for ease of painting. 
 

First mockup of the ribs and thoracic vertebrae using wood supports to hold ribs in place. The ribs provide support and protection for the chest region (heart and lungs).

Paul Collins, Museum Curator of Vertebrate Zoology, is pointing out to the Academy Studios staff modifications needed to correct the rib orientation. Reviewing mocked up sections of the skeleton prior to building permanent steel supports was a critical step during the remounting of the skeleton ensuring that the refurbished skeleton is the most anatomically correct mount of a Blue Whale skeleton.

The sternum is anchored by steel supports to firmly hold the bone in between the first four ribs. The sternum is sponsored by True Blue Friends in honor of Museum Executive Director Karl Hutterer.

New steel supports for bones of one of the front flippers. This steel is located on the back side of the bones and will not be readily visible when the skeleton is viewed from the side.
