| TUSCALOOSA, Ala.
- Fossilized remains of an 80-million-year-old gigantic water reptile,
found in Greene County, will be publicly displayed for the first time
at the Alabama Museum of Natural History
on The University of Alabama campus, beginning Monday evening, March
4.
This particular animal, a type of mosasaur named Tylosaurus,
was about 23-feet long, said Dr. Ed Hooks, curator of vertebrate
paleontology at the UA museum. Initially discovered near the banks
of the Tombigbee River in January 1993 by a pair of U.S. Army Corps
of Engineers rangers, the mosasaurs bones exhibit scarring
indicative of its fierce nature, Hooks said. He estimates that more
than 2,000 hours of work - much of it completed by UA students and
volunteers - went into recovering and preparing the pre-historic
specimen for display.
Mosasaurs were nasty customers, said James Lamb, a
1994 UA New College graduate
considered one of the worlds leading experts on mosasaurs
and who, as a UA student, was heavily involved in the recovery of
this particular animal. If you were in the ocean, you would
have been worried about them. They ranged from 9-feet long up to
about 50-feet long, said Lamb, who is now completing his doctorate
in vertebrate paleontology at North Carolina State University.
The vicious reptiles were ocean dwellers that breathed air and
preferred shallow depths. Some of them were primarily ambush
predators, said Lamb, if you can imagine something that
big hiding. They propelled themselves by moving their tail from
side to side the way an alligator does. They may actually have used
their large bodies to physically trap their prey between themselves
and the beach.
Although mosasaurs lived near the end of the dinosaur age - from
about 90 million to 65 million years ago - Lamb said the species
was not a dinosaur. If you took a big Komodo dragon and turned
his legs into flippers, you would have a mosasaur, he said.
Hooks said museum volunteers have worked tirelessly to make displaying
the animal a reality.
To me, the most interesting part of this has been to watch
so many students and other volunteers in the lab work so hard on
this and enjoy, not just working on it, but learning about mosasaurs,
Hooks said. Of the animals original 23-foot length, about
20 feet of its skull and spinal column were recovered and preserved.
Cleaning and restructuring fossilized bones and bone fragments
is tedious, Hooks said. The work was done, primarily, with dental
tools and toothbrushes. You have some people who may have
labored for a year on a few individual bones of the animal and were
never able to see the whole specimen, he said.
Dr. Harry Blewitt, a professor in chemistry and New College, is
an amateur paleontologist who has volunteered 2-4 hours per week
on the project for the past three years. Im fairly patient,
Blewitt said, and I like working with my hands. Im a
wood carver, so I dont mind sitting down for two hours and
cleaning a little piece of bone.
Some 20 people helped prepare the mosasaur for display and cleaned
and organized the several hundred bones and bone pieces, including
81 vertebrae, Hooks said.
The public will have an opportunity to see the mosasaur, nicknamed
Bossie, on display from March 5-April 7, during the
Museums normal business hours, 10 a.m.-4:30 p.m. Tuesday-Saturday,
and 1-4:30 p.m. Sunday. Admission is $2 for adults and $1 for seniors
and children. Guided tours for schools and other groups can be arranged
on Tuesdays-Fridays by calling 348-9473. The public is also invited
to hear Lamb give a presentation on mosasaurs at the Museum, on
Monday, March 4, from 7-8 p.m. When his lecture is concluded, the
mosasaur display will be opened.
As a UA student, Lamb was working as a member of the Museums
paleontology staff when the Museum was first notified of the fossilized
find at the rather inaccessible site. It was difficult to
work because everything we brought down to use in the excavation
had to go back up this very steep drainage ramp, Lamb said.
When we did get the skull excavated it was within a block
of rock wrapped in plaster that weighed several hundred pounds.
We had a half dozen blocks that weighed that much.
Although mosasaurs once lived around the world, few places make
such good mosasaur fossil hunting as does Alabama, Lamb said. Alabama,
it turns out, is one of the top three places in the world to look
for mosasaurs, along with Belgium and Kansas, Lamb said. In
particular, the soft soil of the Black Belt region, which, along
with most of south Alabama, once lay underneath the ocean, is ideal,
he said.
The Museums staffers and volunteers find various fossilized
specimens much more quickly than they can catalog them, Hooks said,
so the Museum is accepting volunteers to work on various projects.
Free training courses in paleontology are available to volunteers.
Last year we found three mosasaurs during our field work,
and we are going back to excavate them next year.
