"Shootout at the OK Quarry"
Here, Roy and I have a shootout at the OK quarry on Black Cat Mountain.
The last man standing gets the trilobites.
"The quarry operations"
Black Cat Mountain is quarried by
Robert Carroll, a fossil enthusiast to say the least. He carefully mines this mountain for its
world class trilobites. Layers of limestone from the Haragan Formation are carefully excavated and
stacked into piles. These piles are then searched for the trilobites. Later he preps them for
sale at the Tucson Show.
This is the best find of the trip. It doesn't look like much now,
but after it's prepped, this will be a beautiful Huntonia trilobite, one of the more sought after
trilobites on Black Cat Mountain.
"Amy is searching for more trilobites"
Even when the temperature became warm and everyone else was in short sleeves, she continued to wear her
winter parka. Looking at her made us all cold.
The Trilobites are found in the rock, usually when the rock is split, an outline of the bug is
seen on both sides of the split. The rock is then glued back together and prepped.
From April 30th to May 4th, We traveled to Oklahoma and Texas with Roy and “Wrong Way”
Rob from NJ for a fossil trip. The primary goal of this trip was to spend a few

is a world-renowned
preparator of Oklahoma trilobites, and Black Cat Mountain is probably the best place in
North America to find trilobites.
We spent a few days there collecting trilobite specimens such as a Ketternaspis,
Huntonia, Dicranurus, and a bunch of Redops. We also ventured into Texas and hit a
spot near Sherman for Ptychodus teeth, a type of Cretaceous shark (I found one…). Finally,
we took a brief jaunt to a spot for Ammonites. At the Ammonite spot, we all found some ammonites, mostly
fragments though. However, Roy found an interesting arrowhead.
In the end we took back approximately 100 pounds of fossils, mostly trilobites. Enough to
keep me busy prepping for months! Unfortunately, I have been unable to begin prepping the
fossils. I first need a harder abrasive for my air unit. Check back in a few weeks and I
should start to have some pics of prepped specimens.
Yes, the place was chalk full of creepy crawlies. We were warned to stay clear of rattle snake and
scorpion, but no one told us of tarantula! I believe this one was guarding a trilobite.
Besides the creepy crawlies, there were some pretty cool wildlife. We saw a roadrunner... briefly (they are fast!), some neat
looking lizards, and armadillo. The armadillo were curiously laying on the side of the road.. Perhaps
they were resting.
Wrong Way Rob lifted a rock to find this lizard. Although small, he was ferocious and would attack anything

These are "Test" Trilobites. These are usually "float" trilobites (matrix free trilobites
that have eroded out), and thus have cracks and defects in them.
