The program was “Our Other Hobbies” and
there were some very interesting
presentations. We have a very talented group
of members. You just never know what
people are interested in. I’ll summarize
below.
Bill Curtin likes to go deep sea fishing and
competed in a tournament off Ocean City in
which his boat won $42,000 for the tuna they
caught; Bill also collects antique bottles; Joe
Davis makes and shoots his own primitive
bows and arrows out of local materials --- he
had 3 very sturdy bows – 2 of hickory and 1
of osage orange – all with different raw hide
skin glued to the front side with homemade
glue to strengthen the bows – and arrows of
“arrow wood” (a viburnum) and reeds – he
used wild turkey feathers for the fletching and
made his own arrowheads out of different
materials and attached them with sinew and
homemade glue – and he killed a deer with
one of his bows and arrows; Gary Lohman
collects antiques and brought in a very
unusual 1865 patent gizmo that he figured
was a small, portable, lightweight kerosene

“stove” that could be used to melt lead for
bullets on the battle field and was also sized
to exactly fit and heat up the early “C-rations”
used by Union soldiers – Gary thinks it is a
rare one-of-a-kind prototype; Bob Davidson
built his own model railroad at home and
showed us pictures of the various steps of
construction of the layout and an excellent
video of the final product with his train
traveling through a very detailed and lifelike
landscape of mountains, trees, waterfall, river,
sawmill, bridges, log buildings, etc.; Ralph
Gamba surprised us with a great country song
he wrote and sang and played on his guitar –
the song was a funny spoof of country songs
with words which said, “he did not drink or
smoke or fight and he had never been in jail
and was not lovesick nor was sad or lonely”;
Carole Raucheisen likes gardening and
showed pix of her backyard which she and Al
had landscaped into a beautiful oasis with
rock borders and many paths and flowers and
shrubs; Paula Davis raises chickens that that
lay beautiful different colors of eggs and she
bought in several dozen to give away --- blue,
green, light tan, medium brown, chocolate
brown, and some in between; Dave Lines
finds and collects whitetail deer sheds – deer
antlers that drop off each year in late winter,
before the bucks grow new and larger ones in
the spring and summer – he showed about 10
different ones and explained how, where and
when they are the easiest to find. Harry and
Tina League love horses and have Tennessee
Walkers which they take on trail-rides
throughout Southern Maryland --- their horses
like to do this so much that they “load
themselves” into the horse trailer; Harry and
Tina also rescue and care for various animals
--- and take the wild ones to rehabilitation
centers.
Overall, the program was upbeat and
refreshing. Many people stayed around after
the program ended at 9:15 p.m. asking
questions to the presenters and chatting with
each other. Everyone agreed that it was
something worth doing again. “Well done” to
our Program Chairman, Carole, for the idea
and making it happen.

Stars, Pa for invertebrate fossils. Ten (10)
members. Harry was club’s trip leader. (2)
Nov 18, 2017 --- 27th
Annual Richmond Rock
Swap. Good swap. (3) Nov 25, 2017 --- Joint
Trip with CMMFC (Calvert Marine Museum
Fossil Club) to Odessa, Delaware for petrified
wood. 6 members went. Cheryl reported that
trip went well and she found some good
petrified wood specimens. Someone found a
large petrified tree stump across the road from
the farm on the area now being excavated for
the Community College.
B. Upcoming trips ----
(1) Dec 9, 2017 --- Saturday, 9:00 am to 2:00
pm EST, Diamond Hill Mine, Antreville,
Abbeville County, SC. Fee --- $20 for adults
18 and over, $10 for teens and seniors PLUS
since this is a trip sponsored by the Southeast
Federation, attendees must be members of an
eligible club. Lynchburg club in VA will
work. So attendees must join Lynchburg
Club before they go --- $15. You can
download membership application on their
website at http://www.lynchburgrockclub.org/
and mail it asap. See 11-16-17 email from
Dave with full details.
(2) Local fossil trips this winter --- on your
own and Short Notice TBD --- December and
early January usually has best combination of
lowest tides of the year and ice free tidal
waters. December “full moon” low tide on
Sunday Dec 3rd
--- December “new moon”
low tide on Monday Dec 18th
--- January “full
moon” low tide on Tuesday Jan 2nd
. “Blow-
out low tides” can occur if a strong northwest
wind is also occurring for these low tides ---
great time to look for fossils. Suggest Purse
State Park on Potomac River in western
Charles County or Matoaka Cabins ($4 fee)
on Chesapeake Bay in Calvert County.
Check “predicted” times for tides at
http://www.saltwatertides.com . You can also
check “actual current tide levels” at
http://www.tidesandcurrents.noaa.gov//map/
--- which is a great way to see if the tides is
lower or higher than predicted right before
you go.

members have RSVP’ed “Yes” so far.
E. Continued discussion of what to do with
the money in the club treasury. Purchasing
club T-shirts thought to be too extravagant
given amount available in Treasury.
However, Tina will check online and get
some firm costs for bright yellow “safety” t-
shirts so club members can buy them for club
events and field trips. Joe felt that we should
leave the money alone in the Treasury. The
other idea discussed at the Oct meeting of
“giving $50 honorariums to speakers to help
cover their travel expenses” was not
discussed.
NEW BUSINESS: A. 2018 Rock
Club dues are able to be paid tonight since
Glenda is present and she alone on the
CWNC Staff understands how to use their
new computer system.
B. At Gary’s new job, they tested plastic
safety glasses for impact resistance and found
structural weaknesses in all plastic safety
glasses after 200 hours of sunlight exposure.
We might think about buying new safety
glasses more often and keeping them covered
(in the dark) when not in use.

What Do You Do When
Palaeontology Itself Is Endangered
in India? BY SREELATHA MENON ON 20/11/2017
https://thewire.in/198473/palaeontology-
endangered-india/
There are few researchers and fewer teachers
studying vertebrate and invertebrate
palaeontology – leading some to wonder if
India’s story of the evolution of life will
continue to be written for long.

Gujarat. Caption and source: PLOS
There was a lot of excitement when a big
fossil was recently discovered in the Kutch
region of Gujarat by a team of Indian
researchers. However, the very science of
palaeontology – the study of fossils to trace
the evolution of life on Earth – could be dying
in India. Veterans in the field are concerned
that there may not be many fossils being
unearthed in the future as there are hardly any
openings for a palaeontologist in Indian
universities, while the number of students
signing up for the subject has also been on the
decline. According to Mahendra Pal Singh,
the secretary of the Palaeontological Society
of India, about 150 to 200 students pursue a
postgraduate degree in palaeontology every
year in the country. As for research, only
about 15-20 students enrol themselves every
year, he continued. And of these, just three or
four work on research related to
vertebrate/invertebrate palaeontology. The
rest work on areas that have commercial
applications.
“The future of palaeontology in India is bleak.
There are only a few universities where
palaeontology is being taught. The number of
well known palaeontology centres has
diminished for want of faculty,” Singh said.
He thinks the course’s difficulty is an
important factor: “Students are not opting [for
it] because it requires hard field work in
hazardous locations.” But the field itself, as
far as Indian lands are concerned, is rich.
Ashok Mehta, a pioneering palaeontologist
who discovered the first-ever dinosaur fossil
in the country, feels India is an exciting place
to look for fossils. “There is plenty to be
found if only there are people available to
look. But they are not there,” Mehta said.
“The science would be extinct in this country
soon.”
Guntupalli V.R. Prasad, the head of the
department of geology in Delhi University
and the researcher who led the recent
excavation of the big Kutch fossil (an
ichthyosaurus) had been Mehta’s student in
the University of Punjab.
Rocks, Minerals, and Fossils in the News

Mehta continued that the future of the science
depended on the government’s attitude. “The
question being asked … is if palaeontology
can help build a nation. Is archaeology again a
nation building exercise? The government
does not see it as such – or universities would
be appointing teachers in these subjects. Nor
is it attracting many students,” he said.
Research aside, potential students are
attracted to applied palaeontology more
because the job prospects there are greater.
“So universities are not offering courses in
basic palaeontology but in various branches
of applied palaeontology,” according to
Mehta. “Yet without learning basic science of
palaeontology, you can’t [work on]
applications. But no one is bothered about
this.” According to researcher Ashok Sahni,
applied palaeontology broadly includes
branches of study that have commercial
applications in climate studies and oil
extraction. Such branches include
micropaleontology, palaeobiology and
palaeoceanography.
Other applied courses offered by geology
departments in Indian universities are
petrology, seismology, geophysics,
geochemistry, sedimentology, mineralogy,
coal geology, and so on. But a faculty for
vertebrate or invertebrate palaeontology is
rare. While the IITs in Rourkee and
Kharagpur offer it, Jadavpur University,
Banaras Hindu University and Punjab
University don’t. Vertebrate and invertebrate
palaeontology, both of which deal
predominantly with fossil research, do not
often lead to jobs as teaching posts are hard to
come by. Prasad explained that there are also
few experienced teachers, so the odds of
finding good mentorship have been getting
poorer.
“In well-known centres of paleontological
teaching and research, such as BHU,
Lucknow University, Panjab University,
Jadavpur University, etc., the number of
palaeontologists has gone down drastically
and new, prestigious educational institutions
like the IISERs are not showing much interest
in hiring palaeontologists,” Prasad said
(IISERs: Indian Institutes of Science
Education and Research). “So the country has
very few palaeontologists working on large
invertebrate fossils at present.”
Pratul Saraswati, a micropalaeontologist in
the department of earth sciences, IIT Bombay,
thinks it’s not about people not being
interested in palaeontology. “If you ask me to
name some micropalaeontologists other than
myself, I won’t be able to give you more than
five names. If you ask Prof Sahni to name
some vertebrate palaeontologists, he won’t be
able to name more than three or four.”
“The problem is with geology departments as
a whole across the country. Except in the IITs
and central universities, just one or two
faculties teach all the subjects coming under
geology – and that includes palaeontology,”
Saraswati said. “There is no faculty for
geology across India. So it is not just
palaeontology but all the subjects coming
under geology that are taking a beating.”
At the IITs, every subject is taught by a
specialist – which is good because, according
to Saraswati, “It is difficult for a non-
specialist to teach palaeontology.” But in the
ROCK TALK JANUARY, 2018
Page 7 of 13
other universities, “One or two teaching all
the subjects in geology is fine till graduation.
For post-graduation and research,” that will
not be enough. In other words,
palaeontologists and its scientists are
endangered in India. What makes this
situation doubly unfortunate is the fact that
palaeontology as such has been receiving
more attention in other parts of the world.
According to John Flynn, a curator and
professor in the division of palaeontology at
the American Museum of Natural History,
New York, told The Wire, “There is a lot of
active training of palaeontologists in the US.
Both the Palaeontological Society and the
Society of Vertebrate Palaeontology here
have large numbers and percentages of
student members.”
Mehta, in fact, counts Germany, China and
the US as havens for palaeontology research.
Another problem that palaeontologists are
facing in India is that there is no place to
preserve their discoveries. For example,
where will Prasad et al keep their recently
found ichthyosaurus?
“The repository of specimens is a major
problem. As in western countries, we do not
have a ‘Natural History Museum’ for housing
prehistoric treasures such as fossils. All
specimens collected by the palaeontologists
are at present deposited in the university
departments where they work,” according to
Prasad. “Our only worry is that… Once we
retire, what will happen to these specimens?
Since they are not properly conserved, they
may be lost forever.” Thus, the ichthyosaur
skeleton he helped unearth is currently housed
in the department of geology at Kachchh
University. “Most western countries have
many national and regional natural history
museums that are important repositories for
fossil specimens. Therefore, a ‘Natural
History Museum’ in India” is needed
immediately “to conserve Indian fossil
specimens.”
The Natural History Museum in Paris has a
collection of five to six million specimens,
according to the International
Palaeontological Association (IPA).
China’s Shandong Pingyi Tianyu Natural
Museum (in Pingyu county of Shandong
province) possesses the complete fossils of
more than a thousand dinosaurs. Flynn said
that there are many such museums in the US
as well.
Sahni goes a step ahead and thinks India
doesn’t have a tradition of saving fossils. “I
donated the bulk of my fossils to the
Government Museum [in] Chandigarh,”
including his dinosaur egg fossils. “I was
asked to establish a museum for dinosaurs of
India by the then Administrator of
Chandigarh, Lt. Gen. Jacobs,” he recalled.
“Today, on retirement, I have no specimens
with me of any value, i.e., they are not the
type of specimens on which taxa are based.”
“In most other countries there are local
repositories well-cared-for in universities or
in institutes and this is not a problem.”
According to the IPA, there are over 5,000
palaeontologists in the world. Zhong Zhongu,
the association’s president, wrote in an email
to The Wire, “I think palaeontology is a basic
science branch of both geology and biology.
It is critical to science education and museum
studies everywhere in the world. As a fast
ROCK TALK JANUARY, 2018

growing country, India has great potential to
contribute more to the study of
palaeontology.”
Rock and mineral loans
available for Gr. 4 and home-
schooling by Neil Carleton – Metcalfe Geoheritage Park Committee
http://millstonenews.com/2017/11/rocks-and-minerals-
loan-collections-now-available-for-grade-4-classrooms-
and-homeschooling.html
As a pilot project of Metcalfe Geoheritage
Park, loan collections of rocks, fossils, and
minerals are now available for grade 4
classrooms and homeschooling in Mississippi
Mills.
The study of rocks and minerals in grade 4
introduces students to the science of geology.
The best way to learn about rocks and
minerals is to have specimens available for
study. Pictured here, from Rocks Box 9, are
hands-on samples of the metamorphic rock
gneiss.
The 15 loan collections, each in a sturdy bin,
include sedimentary, metamorphic, and
igneous ROCKS – gneiss, granite, limestone,
marble, sandstone, schist, shale – Ordovician
age FOSSILS, about 450 million years old –
brachiopod, cephalopod, colonial and solitary
coral, crinoid, gastropod, trilobite – and
Precambrian age MINERALS, about 1 billion
years old – calcite, feldspar, mica, quartz.
Each loan collection includes a class set of
hands-on samples for students to study,
measure, compare and contrast, classify,
describe, draw, photograph … These
examples, from Rocks Box 12, are feldspar,
an abundant rock forming mineral of the
Canadian Shield in our area.
Each loan collection also has a large specimen for classroom
display. This fossil sample is colonial honeycomb coral from
Rocks Box 1.

During the Ordovician Period, about 450
million years ago, our part of the world was
near the equator. The shallow, tropical
oceans that covered the North American
protocontinent were rich in early marine life.
Their fossils can be are found in the
sedimentary limestone of our area. Diorama

The 8 classroom sets of specimens in Rocks
Box 15 are for student testing. Rocks
limestone + sandstone + shale + marble.
Minerals calcite + feldspar + mica + quartz.
Pictured here are testing samples of mica, a
common sheet or flake mineral of the igneous
and metamorphic rocks of our region.
TEACHER NOTES The illustrated teacher
notes that have been prepared for each Rocks
Box include descriptions, explanations, and a
glossary of geological words.
COST The 15 loan collections are free.
Donations for their upkeep are welcome.
LOAN PERIOD Each Rock Box can be
borrowed for a day or so, or a week, or
longer.
LESSON PLAN Classroom teachers and
homeschool instructors are asked to
contribute a lesson plan to each Rock Box
they borrow.
RESERVATIONS By email on a first-
come-first-serve basis.

John Wolf Memorial Trip to
Odessa Delaware November
25th, 2017 Article and photo by Cheryl Reese
Six Members from the Rock club joined the
CMM (Calvert Marine Museum), DVPS
(Delaware Valley Paleontological Society),
MGS (Maryland Geological Society), DMS
(Delaware Mineral Society) and WVFC
(West Virginia Fossil Club) on a field trip to
Odessa Delaware to look for fossilized
Cypress wood from the Pleistocene and
Miocene eras. It was a beautiful sunny day as
ROCK TALK JANUARY, 2018
Page 10 of 13
we met up at the park and ride, given
instructions to the site and off we went. I
believe there may have been at least 25
people. Once there, we had 4 acres of corn
field to look thru which was very difficult as
the corn stalks and the fossil wood are
basically the same color. There was also a lot
of green “weeds” throughout which someone
said the farmer probably planted to enrich the
soil for next years planting. I walked the
entire length and back of a row of corn using
my garden scratcher to push away the corn
stalks resulting in very little material. I only
found a few pieces which were very small.
We had heard that larger pieces had been
found a week earlier across the road in a field
that was being excavated for a new building.
Several people went over and I was told they
were finding small pieces of wood. I drove
over and had much more success finding
larger pieces that were just lying on the
furrows left by the excavators. I ended up
with several pieces of 4+ inches and
numerous smaller pieces. I had a hard time
leaving the area thinking, “just one more
piece”, which is what I do when sharks tooth
hunting. Always believing the next one found
will be the biggest. There were only 2 people
left when I finally decided to call it a day.
Field Trip Report: HK PENN-
MD Quarry, Peachbottom, PA by: Tina League; photos by Cheryl Reese
On Saturday, December 2, 2017 eight
members of SMRMC (Cheryl, Orion, Aby,
Tim, Joe, Jim, Harry and myself) accepted an
invitation from Dave Fryauff of GLMS-MC
to join in on the mineral collecting trip at the
HK PENN-MD quarry. Members from the
Delaware club also joined the group of about
30 or so attendees. Everyone managed to
survive through the cold early morning safety
briefing and paperwork signing. Once the
business was concluded, everyone hopped in
their WARM vehicles to drive down the 4
tiers to the bottom of the quarry. With safety
gear donned and buckets/tools in hand, we all
fanned out across the quarry to see what we
could find.
There were plentiful serpentine specimens in
many shades of green. Williamsite (a
translucent green chrome mineral that
polishes like jade) was the key mineral that
was searched for. Tim stated that he found
some dark green mineral which might take a
good polish, but not sure what it was. We all
found beautiful serpentine specimens and
some magnesite. There were plenty of other
ROCK TALK JANUARY, 2018
Page 11 of 13
mineral specimens in a multitude of colors
that I have yet to identify. The rocks were
broken up into many different sizes (from
large boulders to small fist size-pieces that
didn't require any hammering). They only real
labor required was hauling heavy rocks to the
truck or reducing some of the larger ones
down to a reasonable handling size. The
serpentine "flakes" of green that were
scattered across the quarry floor were very
nice for collecting. The colors ranged from
"dull to very dark" green. The sunshine did a
nice job of warming everyone up as the
morning progressed.
The noon quitting time arrived in the blink of
an eye and as usual.....I had to be dragged out
of the quarry by Harry and Joe. We were the
last ones to leave and thanked our host for a
wonderful day. We would like to return to
this site in the future. The drive home to
southern Maryland was pleasant and
uneventful....in other words, we didn't get
lost. Yeah!
