Fossil is taken to the Fossil Lab.

Fossil is soaked in n-propyl bromide,

then cleaned and repaired if necessary.

Soak the matrix in solvents.

First in biodiesel and then in n-propyl bromide.

Let matrix dry. Remove coarse material

and delicate fossils by hand.

Matrix is placed in a one gallon

bucket and taken to the Fossil

Lab.

Matrix is sorted in the Fossil Lab.

7x-45x microscope is used
