Paleontologists
and scientists from the University
of Nebraska State Museum
excavate a site in late May near the
town of Center to
uncover fossils from a plesiosaur. More than
1,000 visitors
checked out the progress of the dig, which uncovered
about
one-third of the dinosaur's neck vertebrae, but not its
head.

Uncovering a dinosaur
Museum
workers piece together a plesiosaur
pulled from its home after 70
million years
By Kelly Bartling, University
Communications
Some 70 million years ago, in the great sea
that once covered
Nebraska, a giant lizard-like plesiosaur swam.
When it died,
its bones settled on the ocean floor, where it
remained undisturbed.
Until Mike Baldwin, a science teacher
from Texas, discovered
parts of its skeleton in dirt eroding from
the hillside along
Highway 84 near Center, in north central
Nebraska. Baldwin, a
fossil enthusiast, carefully recovered two
neck bones, about
the size of coffee cans, and knew he had
something exciting.
He figured he had a plesiosaur and contacted
the University of
Nebraska State Museum.
On May 20,
Baldwin, who hails originally from Creighton, Neb.,
Mike Voorhies,
Shane Tucker, Bruce Bailey and Greg Brown of the
State Museum began
a two-week excavation that uncovered the fossil
they now call the
Baldwin Plesiosaur and moved it to its new
home in Nebraska
Hall.
The project, which is the first major dig in 2003 for
the
museum, marked a significant find for the Highway Salvage
Paleontology
program.
"It's a red-letter day
when someone finds one of these
creatures," Voorhies said in
May, holding a shovel from
his spot overlooking the fossil dig,
unable to hold back his
enthusiasm. "Who has ever seen an
actual sea monster in
the rock?" he asked. "Not very many
of us. I think
people in Nebraska don't even realize that we had
things like
that living here."
As many as 1,200
visitors stopped to look at the excavation
- small groups of school
children, families passing by, local
curious, and the media - while
the group carefully uncovered
the bones, covered them in tissue
paper and plaster casts and
removed them from the shallow roadside
cliff. They now sit waiting
further study at Nebraska Hall, where
Bailey and other co-workers
and volunteers will continue to use
tiny flexible knives and
brushes to extract the bones from the
chalk and piece the specimen
back together.
Bailey
said the specimen is probably a long-neck plesiosaur,
and only the
sixth articulated specimen found in Nebraska during
the 130-year
history of fossil-collecting in the state. About
one-third of the
60 to 70 neck vertebrae were recovered, but
not the skull, which
would have been an extremely rare find.
"An
articulated specimen (with its bones joined) like
this is
incredibly rare it's probably the second-best one found
in
Nebraska," Bailey said. Another lies in the floor of
the
Mesozoic Gallery in the State Museum, under plexiglass where
visitors can walk along the length of its neck.
The
scientists were a bit disappointed not to find the skull.
At the
dig site, the vertebrae suddenly ended, and Bailey points
out that
the last several appear to have bite marks.
"I would
envision a bloated carcass of this plesiosaur
floating around the
sea and the sharks biting at it," he
said. "That's part
of what we do during preparation try
to understand the cause of
death" and other details about
the prehistoric animal. The
paleontologists were also interested
in finding a complete paddle,
or arm-like fin. This specimen's
paddles were somewhat
scattered.
The great water creature is a nice addition to
the museum's
collection, Voorhies said.
"These
aren't fossils Nebraska is famous for. If you
go to our museum, the
outstanding fossils tend to be the big
land animals, the giant
mammoth and saber-tooth cats and the
world's largest camels. These
fossils are much older," he
said. "This skeleton is 70
million years old, which is about
seven times older than the
Ashfall Fossil Beds. To most of us,
10 million years is a huge
amount of time. Seventy million is
almost unbelievable. I get
excited at seeing something in this
good of shape and it's that
old."
The find is also a boost for the Highway Salvage
Paleontology
program, administered by the Nebraska Department of
Roads and
UNL. Because of the wealth of fossils in Nebraska's soil,
which
may remain undisturbed except through road construction, the
Highway Salvage Program is a huge success, and nearly unique
nationally.
"Every summer that the Highway Salvage
program has been
going, at least five or six of what I would call
major finds
have been made," said Bailey, the program
director. "There
is so much road work going on in Nebraska and
so many fossils
just under the soil, that pretty much every major
earth-moving
project in the state uncovers some bones. Over the
years, thousands
and thousands of fossils would have been lost to
science and
the state without the program."
Some
of the ability to prepare the fossils has been lost because
of
museum budget cuts, Bailey said, which he said is unfortunate.
"These things belong to the people of Nebraska,"
Voorhies said. "They pay their taxes for roads and for the
university, and here's a case where the Department of Roads and
the
university collaborate on a project that rescues these priceless
treasures. We're proud of that."
Greg Brown, chief
preparator in the Division of Vertebrate
Paleontology at UNL, said
"you'd think after a quarter century
of doing this it gets to
be old hat. But it never does. Every
time you're involved in an
excavation, you're seeing something
no one has ever seen before. It
may be the same species that's
been collected before, but that
individual which was once a living
creature, you're the first one
to see it. And the second thing
you think about is the great
responsibility that carries with
it, this animal's been preserved
for millions of years, you're
now attempting to preserve it for
future generations. That's
a great responsibility."
Edwards
to
resume teaching
Richard
Edwards, senior vice chancellor for academic affairs,
will leave
his current post as of December. He will move to a
teaching and
research position in UNL's College of Business Administration.
Edwards has served as senior vice chancellor for academic affairs
since April 1997.
"I look forward to returning to
teaching and research,
although I regret leaving the administrative
team with whom I
have worked so closely these last six years,"
Edwards said.
Edwards will be a professor in the
department of economics
with his assignment split between economics
and the Center for
Great Plains Studies.
"Rick
has provided outstanding leadership during his
tenure in academic
affairs," said UNL Chancellor Harvey
Perlman. "He has
made the university a better place, and
I'm pleased UNL will
continue to benefit from his wisdom and
vision as he makes this
career move."
Edwards, 59, earned his bachelor's
degree at Grinnell College
(1966) in Grinnell, Iowa. He then earned
his master's (1970)
and doctoral (1972) degrees in economics at
Harvard University,
where he was also a research associate in the
Harvard Graduate
School of Education. He joined the economics
faculty at the University
of Massachusetts at Amherst in 1973 as an
assistant professor.
He was promoted to associate professor and
then professor at
Massachusetts and chaired its economics
department from 1984
until 1991, when he left to become dean of the
College of Arts
and Sciences at the University of Kentucky. He
joined UNL in
1997. Edwards is the author or co-author of 10 books
and more
than 50 articles on economics, history and topics in
higher education.
The senior vice chancellor for academic
affairs is the chief
academic officer for the campus and is second
to the chancellor
in the university's organizational chart. The
office provides
leadership and support for academic programs and
serves as chief
advocate for faculty and students.
A
national search will be launched to fill the vice chancellor's
position.

Sisters launch science education
program
By Rayna Watson, Special to the Scarlet
Just ask twin sisters Anita and Sunita Gupta if they are eager
to teach Nebraska high school students more about science, and
you'll get an enthusiastic yes.
Anita and Sunita, who will
be sophomores in the J.D. Edwards
Honors Program in the fall, have
used their four years of high
school experience competing in
science bowl competitions to launch
a program called JustASK
(Advancing Science Knowledge).
Just...ASK offers free
interactive seminars to Nebraska high-school
students to enrich
their scientific knowledge. The goal is to
educate the students so
they become more interested in the sciences,
more informed about
science careers, and more competitive in
regional and national
science contests.
Sunita and Anita know how important
programs like Just...ASK
can be for high school students who may be
undecided about what
career path to take.
"I
didn't know what I wanted to do when I was in high
school. I knew I
liked math and science but that was about it.
I didn't know what I
could do with it," said Sunita, a computer
engineering major.
"I went to a summer program one year
involving trigonometry
and computer science. After that program
I realized how much I
enjoyed going there everyday and working.
That's when I thought I
would really like to continue doing this
for a living. Then I
realized I could. That's how I chose my
major."
That is the kind of impact the sisters hope to have on the
participants of their program. By increasing students' knowledge
of
different areas of science, they hope to show the students
there is
a world of possibilities for their education and careers.
"The more people know about the different science topics,
the better they can choose a field," Sunita said. "There
are a lot of other things you can do with natural sciences. You
don't just have to become a doctor or a scientist."
The seminars are also meant to increase Nebraska students'
competitiveness in state and national science competitions such
as
Nebraska Science Olympiad and National Science Bowl.
Sunita
and Anita were moderators at the Nebraska Science Bowl
at UNL last
February. There, they noticed not all the teams were
prepared for
the competition.
"At the end of the day, we talked to
some of the teams
and found out that many of them came without a
lot of practice,"
Sunita said.
This surprised
the sisters, who had participated in the Kansas/Missouri
Science
Bowl during all four years of high school in the Kansas
City area.
Their senior year, they took first place in their
division after
countless hours of studying and spending three
days in seclusion
with their team preparing for the regional
competition.
This year, their high school team came to compete in the Nebraska
Science Bowl and outperformed the Nebraska teams, breaking the
record for the highest score by more than 100 points. The sisters
decided to start JustASK to raise the level of competition at
these
events.
The sisters kicked off the series with four
two-hour seminars
on Saturdays in March and April at the Kauffman
Center, with
each seminar focusing on a different topic: physics,
computer
science, biology and chemistry. Plans are in the works for
fall
JustASK seminars to focus on math and Earth science. All of
the
subjects are covered in Science Bowl competitions.
The seminars are interactive with presentations and demonstrations
and offer beginning and advanced lessons for whatever level the
students are comfortable with.
"That way, if someone
has never had exposure to the topics,
they'll just learn the
basics," said Anita, a consumer science
and pre-medicine
major. "And if they know a lot about it
and they're really
interested, the advanced class will help to
expand their
knowledge."
At the end of each seminar, participants
compete in a small
mock Science Bowl, and each is given a packet
including the concepts
and equations discussed during the seminar.
About 15 students
attended each of the spring sessions, and the
sisters have approached
many Nebraska schools to inform them about
JustASK. They hope
the fall seminars will attract about 30 students
each session.
The seminars are sponsored by the J.D.
Edwards Honors Program,
the College of Engineering and Technology,
the Natural Resources
Conservation Service and Runza.
The sisters say they hope JustASK will reach out to smaller
schools in Nebraska. Anita said many smaller schools don't always
have the same exposure to sciences that larger schools do, and
she
found smaller schools could benefit most from all the resources
Just...ASK has available.
"We hope that students
might come to our program and
find something they are very
interested in and pursue it more,"
Sunita said. "We want
them to take an interest in science
and explore it."
Rayna Watson is a senior advertising and broadcasting major
at
UNL.
