"A Trilobite Tale"
Trilobite tail found in very hard matrix. Nearly impossible to remove
with hand tools with out breaking the fossil.
Once a section is removed chiseling along the
base of the block, will cause it to break free.
Was it worth the time to cut out a trilobite tail?
It was the largest we have found in this formation.

Carl and I often talked about creating a web page which would
demonstrate the step-by-step techniques we use when cutting
out a fossil with the rock saw.
When we spotted this fossil ... I said "The light is perfect and
I brought my camera. You do the work and I'll take the pictures."
We always have fun when we go into the field.
