The air is humid, the temperature
stifling, birds call through the dense
jungles and a lizard slithers through
the tall grass. Insects buzz annoyingly
and a crocodile slides into the water
beside "a seemingly undisturbed
elephant.
.. Sounds like Africa' or maybe a
remote South American jungle, but it
isn't. The scene describes Nebraska .
. , 20 million years ago.
"Too many people just think about
Indians and settlers, maybe several
hundred years, when they think about
Nebraska's history," according to Dr.
C. B. Schultz. Schultz, curator for the
University of Nebraska museum in
Morrill Hall, said, "Nebraska "has a
very rich geologic history that goes back
millions and millions of years."
The world famous paleontologist said
the -state was under water, shallow
lakes, much of the earth's history but
"when terrestial life began, and from
that time on, at least some part of
Nebraska was dry land." Such a history,
Schultz said, has made Nebraska im
portant to paleontology.
While many Nebraskans are familiar

with famous names like Morton, Bryan,
Pershing and Norris, few would
recognize names like Gomphotherura,
Aphelops, Stenomylus hitchcocki or
Dinictis. Yet these names have made
Nebraska equally famous.
The geologic history of the state
and Morrill Hall are almost synonomous.
At the University museum the history
of life as far back as the Cretaceous
(180 million years ago) is laid out in
exhibits.
Elephants and Giants
One of the best known exhibits is
known as Elephant Hall. There visitors
can see the giant four-tusked mastadon
. skeleton, the wooly mammoth, the scoop
mouthed mammoth that roamed the
state, and compare them with today's
Indian and African elephant.
Elephant Hall is also the site of
the world's largest known elephant
skeleton, a mammoth found near Lin
coln. Schultz said a new exhibit, the Hall
of Giants, features an 18-foot-high and
30-foot-long beast called the
Baluchitherium. This life-like reproduc
tion ofthe world's largest land mammal,
a giant ancestor of the rhinocerous, will
join elephants, giraffes and other

animals we consider "big" today.
The museum is also proud of a
skeleton of the Aphelops, the world's
largest mounted skeleton of an American
rhinocerous. Variations of this animal
roamed Nebraska during the Tertiary.
The animal most important to the
state's fame, however, Schultz said, is
the camel. The origin of all camels,
from the llama of South America to the
humped backs of Asia, can be traced
to their ancestral home in Nebraska
over 35 million years ago.
Camels haven't been missing from
the state for a very long period of
time, geologically speaking, Schultz said.
Twelve-inch high gazelle-like camels
lived in Nebraska only 8000 years ago.
The remains of the chief predators
of the early camel are also often found
in the state. This fierce predator, the
saber-toothed tiger, is the same animal
that is the house pet of the Flintstone
cartoon family.
Nebraska was . also a tromping
ground for the dinosaur, giants of the
Reptilian era.

Tooth transplants
safe and
by Dana Parsons
NU School of Journalism
The life-saving successes of heart
transplants made up perhaps the most
dramatic medical story of the past
decade.
These operations no doubt caught
the public's fancy because of the dif
ficulty and risk involved in the process
of substituting one human heart for
another. Failure meant death and even
a successful operation could not insure
a person against a future coronary
malfunction.
But there is one kind of transplant
which has become a fairly routine
surgical task, so much so that it is
successful about 90 per cent of the time.
This is the tooth transplant.
Dr. Alvin E. Kleitsch, assistant pro
fessor of oral surgery at the University
of Nebraska's Dental College, said the
success ratio is high because surgeons
are very careful in choosing patients
for dental transplants.
"Several conditions must be met
before we'll even consider a dental
transplant," Kleitsch said. "First we
must be sure the person's oral history
warrants such an operation.
"Several conditions must be met
before we'll even consider a dental
transplant," Kleitsch said. "First we
found in the Cornhusker state is the
duck-billed dinosaur called the
Hadrosaurs or Trachodonts. They fre
quented the shores of rivers and lakes
that dotted eastern Nebraska during the
latter part of the Cretaceous era, 80
million years ago.
Also on display is the head of the
most terrifying dinosaur of all time,
the flesh-eating Tyranosuaurus "Rex,"
the king of dinosaurs. This reptile stood
tearly 20 feet high and is the largest
terrestial flesh-eater in history. Its knife
Jike teeth were often over seven inches
long.
Also on display is a full skeleton
of a Steosaurus, a plant eating dinosaur
with a spine covered with bony plats
and long spikes in its tail.
A host of other fossils from the
dinosaur era are on display in Morrill
Hall. Visitors can see everything from
the femur (thigh bone) of a 40 ton
Brontosaurus to the flying reptile.
If individuals don't know what role
the Piccary Platygonis Leptorius plaved
in the history of Nebraska, Morrill Hall
has that answer and many more.

must be sure the person's oral history
warrants such an operation.
"Second, we must be sure there is
adequate width between the teeth where
the transplant is to be made," he said.
"Also, there must be no pathological
condition present in the host site."
Patient is Donor
Tooth transplants are somewhat dif
ferent from other transplants in that
the new tooth comes from the patient
himself. Kleitsch said the most frequent
recipients are young people whose teeth
have not fully grown.
"There is often a loss of the first
permanent molar in the teenager," he
said.' 'We can take the developing third
molar and transplant it to the site of
the first molar."
This is possible, Kletisch said,
because the third molar can grow back
whereas the first molar, once lost, can
not. "After the transplantation," Kleitsch
said, "acrylic wire is tied in a figure-8
pattern between the teeth on either side

of the transplant. This affords stability
to the new tooth."
As would be expected, much pro
gress has been made in dental
transplants since they were originally
performed in the early 1950's.
Few Transplants Here
"The operations used to be done
in the surgery ward," Kleitsch noted.
"Now we can do them here at the
school."
Kleitsch recalled only one transplant
performed at the Dental College in the
past few years. It was done for a 16-year-old
boy in February, 19.
"As far as we know, that operation
was a complete success," Kleitsch said.
"We don't do many transplants here
because the operations are a little
beyond the undergraduate level."
Despite the relative ease of
transplanting teeth, the practice still is
not widespread. "There are so many
other ways to save teeth," Kleitsch said,
"that we just don't need to use it that
often. It is sort of a safe last resort.

to consider the neighboring teeth. People
don't realize that the damage done to
one tooth affects the whole dentition.
"We can't predict with complete ac
curacy that the new tooth will grow
properly. If it doesn't, then it can affect
the teeth above or on either side of
it."
Simple Operation
The mechanics of the operation are
simple," Kleitsch said. "We can use
either local or general anesthesia," he
noted. "After the transplant has been
inserted, it must remain immobilized
for two or three weeks."
What risks are involved in dental
transplants?
"Since we do select our cases rather
discriminatcly, we are usually suc
cessful," Kleitsch said, "but there are
some risks.
"Since we are manipulating with
tissues during the operation, there is
the fear of making a mistake. The only
other problem is that sometimes the
new tooth will stop developing and fail.
But we can't predict this."
