Spring
2003:
Mammoth
Lab
Before the Spring 2003 term began, a temporary lab for
the mammoth project was built in the Interpretive Center
– the old part of Watson adjacent to the new Science
Center. This large room is ideal for the mammoth lab because
plans were already underway to convert the space into
a science museum. With large windows along the side, people
can watch our progress as we bring the mammoth bones inside
in their plaster jackets (“biscuits”) and
begin to remove the jackets and clean and harden the bones.
Excavation
The first thing we did this spring at the excavation site
was to remove all the insulation that we had buried the
mammoth in for the winter. We used a shop vacuum to remove
the styrofoam peanuts that covered the bones. The whole
process only took us two hours, much less time than if
we had buried the bones in dirt. The bones appeared to
have been protected from freezing and thawing, our main
goal.
Next
the students widened the pit by one meter to the west
and to the north to further expose several large bones
that had been partially exposed in the fall. During the
term we fully exposed the right scapula (shoulder blade),
the left femur (upper leg bone), and the left humerus
(upper arm or foreleg bone). We successfully pedestalled,
plaster jacketed, and removed to the lab our first large
bones – the right scapula and the right humerus.
We also discovered and only partially exposed the left
scapula and possibly the right femur.
Early
in the quarter, the class went on a 3-day field trip to
Elephant Hall in the University of Nebraska’s State
Museum where we saw many skeletons of mammoths and their
ancestors on display. Then we went on to The Mammoth Site
in Hot Springs, South Dakota, where they have found 52
mammoths in a 26,000 year-old sinkhole.
