Near table – students are f=
inishing
cleaning the left femur (upper leg bone) that was nearly completed in the =
fall
term. Center table – students are learning how to remove field jacke=
ts
from small bones (rib pieces and vertebra). Far table – field jacket=
is
being removed from the right femur that had been found under the tusks.
Students are removing matrix (dir=
t or
specifically loess) from what was the underside of the right femur. The bo=
ne
was in fairly good condition and cleaned up nicely. They finished both sid=
es
during the term.
Three half-shell storage jackets =
were
made during this term, an all-time record. One was for the left femur (upp=
er
leg bone) that was completed early in the term. The other two were for both
sides of the right femur which was begun and finished during this term. It
arrived in the lab cleaner than most other bones because it had first been
exposed and worked on in the garage rather than the field.
Right femur in both storage jacke=
ts. Legs
were added to the upper jacket so that the bone could be flipped over and
uncovered on either side.
Several small pieces, including r=
ib
fragments, a small vertebra, and possibly a foot bone, were prepared ̵=
1;
unwrapped from their field jackets, cleaned, and consolidated.
A large block of at least 5-6 ver=
tebrae
was unwrapped and worked on next in honor of the late Tim Colley, a former
student who exposed these bones in 2003.
The class is just beginning to re=
move the
matrix (dirt) from the underside of the vertebrae. Mason trowels and water=
are
used when we are not too close to the bones.
The vertebrae have been found fro=
m the
underside a few days later, and the work slows down as students shift to
bamboo skewers and paint brushes to remove the remaining matrix. Bones are
consolidated daily after new areas are exposed.
The vertebrae include the axis (l=
ower
left), two cervical (neck) vertebrae (upper left and center right), and two
thoracic vertebrae (top and bottom right). A few other parts of vertebrae =
were
found as well.
Students give tours to Principia&=
#8217;s
preschool. This year we have had over 1600 visitors.
Another tour group sees the skull=
block
in the garage. Groups see both the lab and the skull block in the garage.<=

Slide 1
The task this quarter was to redu=
ce the
skull block by removing as much matrix and other bones as possible. This
included removing the right tibia (lower leg bone or shin), which was in
contact with the left tusk. Our ultimate goal is to be able to turn the sk=
ull
block over so that we can clean the other side.
We tunneled under the right tibia=
in
order to wrap it with plaster, securing it before trying to separate it fr=
om
the tusk. There was some damage to both the tusk and tibia as we separated
them.
Students removed as much matrix f=
rom
under the tusks, tusk sockets, and skull before we wrapped them in plaster
jackets.
First we put wet toilet paper ove=
r the
tusks and skull before adding a plaster jacket; the toilet paper is a
separator so that the plaster does not stick to the bone or tusks.
The skull has been wrapped in a t=
hin
layer of plaster gauze over the toilet paper.
Next we sprayed expandable foam a=
round
the skull to strengthen the package while keeping it light. We will eventu=
ally
add a plaster burlap jacket over this, but we will need to include pieces =
of
wood to strengthen the block and keep it from breaking as we turn it. A lot
more preparation is necessary before we are ready to turn it over.
Last day of class – a group=
of all
seniors ready to graduate! They did a great job this quarter – a lot=
was
accomplished.
