February 18th and March 17th. TXI Cement Quarry. We will
meet at 9 am at the first parking area on the left as you enter the quarry.
PLEASE BE ON TIME WE ARE ONLY ALLOWED TWO HOURS IN THE QUARRY. The site
is Cretaceous Period. The area to search is he contact at the base of the
Austin Chalk (Atco Member) and the under lying Eagle Ford Shale. What to
bring: Rock
hammer, sturdy shoes, small collection containers or bags. Bring buckets
if you plan to bulk sample. What
fossils can be found?
The site is marine deposits and produces relatively abundant Ptychodus,
Cretodus and other shark teeth. Occasional mosasaur verts and jaws have
been found. Turtle and fish material is also fairly common. The trips
will be limited to 25 people maximum. You may not attend both trips unless we
don't reach the assigned number. Open slots will be for members
only, but five days before each trip any remaining slots will be open to
anyone. Please contact Polly to reserve you
spot on the list. 903-968-3057 Pollym@airmail.net

We will meet at 9AM at Fort Richardson State Park main entrance 1 2/3 miles
north of intersection of highways 380 and 199 both from the Fort Worth Dallas area
and about 1 mile south of downtown Jacksboro. Jacksboro is about 90 miles
northwest of the Dallas. See map.
After adults gets a park permit for $3
(or bring you Texas park passes), we will head north and east on highway
59 turning right on Lost Creek road a drive about ¾ of a mile to a
right turn on a road leading to a small parking area next to the dam. Since the area may
be muddy, bring boots, a change of clothes and a large garbage bag. Heavy rain
will cancel the trip. A rock hammer would be useful to dig the fossils out of
the clay and silt of the Pennsylvanian Finis shale of the Graham Formation. Please email me,
John Christian: jmc62@sbcglobal.net
or call my office 972-516-4282 before 3 PM on January 20th so
that I can send you a list of those going to help coordinate carpools.
Call my cell phone AFTER 5PM Friday 20th if you have any
questions: 510-559-0110.
Parking is tight, so try to carpool. Polly has two trips planned for Nebraska in 2012. Polly has
two trips planned for Nebraska in 2012. She would like to know who among those
with a raincheck are interested in attending one of these trips. Contact: pollym@airmail.net
On you own: Are
you aware of the DPS's coordinated with the City of Mineral Wells
to establish a fossil collecting park? This is a great place for a
field trip to collect on your own. Find out more about Mineral Wells Fossil Park.
Geology: Before
going into the field a little background information may be useful.

FIELD TRIP BASICS
COMMON FIELD TRIP QUESTIONS. If you have a question and the topic is not specifically addressed in the trip description it is always best to ask the Field Trip Leader.
Are kids and dogs
allowed on trips? Typically, they are allowed to participate except for
quarry trips. However, take into consideration the terrain,
distance walking and weather conditions from the parking area to to
farthest point you may collect. Can your child or pet walk go the
distance?
What do I need to know if we are going to a quarry? You must be an Active Member
to participate on quarry trips. Unless there is an exception, persons
under the age of 18, and pets are not allowed. Hardhats,
protective eye wear and steel-toed boot are highly recommended and
sometimes required. Sometimes, the quarry will provide hardhats. If
these items are not mentioned in the trip description, ask the trip
leader.
I am not a member can I go on a trip?
Generally, Yes. Field trips are considered a privilege of membership.
Sometimes members dues help pay for different aspects of a trip. Some
trips have a limited roster and showing up out of the blue might just
ruin the day for yourself and maybe others. If you want to go on
one or two trips to see if you would like to join feel free. Just
remember, paying customers don't like free-loaders.
I won't be able to make the trip on that day but on another day, where are you going to collect?
Specific field trip information is rarely given out. There have been
times when people jump the gun causing many problems. First, every site
requires permission from the landowner for anyone to collect. Just
because the society has permission on a specific day does not mean
members can go whenever they please. "Jumping fences" makes you and the
Society look bad. So don't. Second, going before the group, if you
don't get arrested or shot at, is not fair to those who go at the
designated time. Going afterwards may mean the site has been picked
clean.
WEATHER: North
Texas weather is hard to forecast except in the summer, typically very
hot and dry. The rest of the year the weather can change quite rapidly.
Check the forecast before you leave the house. You may be caught by
surprise but at least you checked, right?
WHAT TO WEAR AND BRING: Prepare
for the weather conditions for the entire trip. Depending upon the time
of year there can be a dramatic need for different clothing from
morning to afternoon (or evening if you camp). Always bring plenty of water. Whether it is winter or summer underestimating your fluids intake can be lethal.
Snacks
and sack lunches are based on personal preference. Typically, an all
day field trip will stop at a location with at least one restaurant. Of
course you can always bring brown bag lunch.
Wear tough shoes
like work boots or hiking boots if the terrain in rocky and steel
toed boots for quarry trips. Sneakers/tennis shoes or any type of
open-toed shoes are unacceptable, fire ants is one good
reason, except for some places like open, generally level fields
and creeks. If collecting in creeks or rivers in cool or cold weather,
a pair of knee high rubber boots or half-body waders will keep you
dryer and warmer. Knee pads and gloves! Knee pads can be found at
local home improvement stores, some gardening centers and carpet supply
stores. One good type of glove used by weight lifters and cyclists have
the finger tips open for grasping while the palm of the glove is
padded.
Things to carry your fossils in: They can be
backpacks, buckets or sacks. Plastic baggies are always a good thing to
include. These can be easily labeled especially if there are multiple
collecting localities. Film canisters (a soon to be trace fossil) and
medicine bottles are excellent for storing small and fragile fossils.
Bring tissue paper to wrap the delicate or small fossils. For
larger specimens, newspaper or aluminum foil is good for wrapping and
protecting your goodies.
Equipment: This
is wide open. Of course the matrix that you will be digging in will
dictate the tools that you use. Ask before you head out. Some never
fail items are an ice pick or awl, a rock hammer and one or more cold
chisels. If you plan on using a hammer, please wear safety glasses.
Other
equipment: A camera! Photos of in situ fossils are sometimes better
than after you dig it out. Plus, you can get pictures of the others on
the trip. Bring some small brushes, a sledge hammer (even a short
handled 4 lbs hammer saves a lot of work). Dynamite is never allowed.
(Bummer, it could come in handy.)
Bringing crowbars,
pulleys, ropes, signal flares, and winches or wenches is only limited
by how much you want to lug around.
Comment about limited roster field trips.
Please do not accept a
spot on a limited roster field trip and then not show up. This is very
inconsiderate to other members further down the list. If you know you
are not going to make the trip, contact the field trip leader in a
timely manner to allow for others on the roster to move up.
Additionally, if you are not on the roster and show up unannounced the
day of the trip there will be no exceptions made to accommodate you.
Most
quarry trips are member only trips and many of them require limited
numbers of people, so I have to maintain a list. It is difficult for me
to tell who is an active DPS member. So, this is the plan:
- The
field trip leader will check the name of each person signing up for one
of these trips against the current membership list.
- If you are not on the list, you will not be put on a limited trip roster.
-
You must have been a member for at least 30 days. Even though new
members are anxious but it is necessary to verify your membership. Especially, if you mail in your application to our P.O. Box.
-
This means that I will not accept, "I am joining this month and want to
go" or "I will mail in my membership now so I can go" requests.
-
Simply, if you did not get a newsletter the previous month I will not put
you on the roster for a limited person trip. So, those folks who were
members in January and got a March newsletter you would have be
eligible for the list. Those joining in early February would have to
wait until the next month.
