A new preparation lab was added to accommodate Sarah the Stegosaurus.

The new preparation lab has plenty of room and all the equipment needed to properly prepare this unique and rare specimen.

As bones are removed from their plaster jackets they are cataloged and preparation is begun. Work progresses on multiple bones or jackets at one time.

Bob Simon and Kirby Siber discuss the progress of the preparation of Sarah at the prep lab.

Bob Simon is holding one of Sarah’s upper arm bones or humerus.

This is one of the larger back plates of Sarah.

This is one of the small tail plates of Sarah.

Here are three of Sarah’s tail plates.

This is one of the small neck or cervical plates of Sarah.

One of Sarah’s femurs that has been partially prepared on the table.

Another view of one of Sarah’s femurs with Yolanda Siber nearby. Yolanda is one of the skilled preparators working on Sarah.

This is one of Sarah’s lower legs. It includes the tibia, fibula and metatarsals. Phalanx and unguals were separate from this assemblage but nearby.

This is one of Sarah’s shoulder blades or Scapula with the associated coracoid.

Sarah’s skull was disarticulated but appears to be contained to one or two large blocks that were at the end of the cervical or neck vertebrae.

The ribs were very fragile and require great skill to stabilize and prepare.
