The fossilized remains of a large meat eating
dinosaur were recently recovered from the Bisti Badlands, south of
Farmington, New Mexico. The remains of this dinosaur are probably those of
a large Tyrannosaur, Albertosaurus. They appear to be the most
complete specimen of a meat-eating dinosaur ever found in New Mexico.
The skeleton of this dinosaur was removed in two
pieces after being encased in a protective plaster "jacket",
each weighing nearly a ton. Because the skeleton was located in the remote
and inaccessible terrain of the Badlands, it was removed by helicopter and
deposited on a large flatbed trailer for transport to the New Mexico
Museum of Natural History and Science, in Albuquerque, NM.
The Albertosaurus skeleton is an extremely
rare find and is of exceptionally high scientific value. It is estimated
that 40 to 60% of the skeleton was preserved. Albertosaurus was
every dinosaur’s worst nightmare. It was a formidable predator that may
have attacked in pairs or small groups.
Paleontologists have studied and researched this
area for nearly a century. The Badlands feature an exposure of rocks known
as the Fruitland/Kirtland Formations that represent a time near the end of
the Cretaceous Period (approximately 75 to 80 million years ago). These
continental sediments chronicle the time near the end of the Age of
Dinosaurs. This sequence of rock formations is one of only four known in
the world that record this transition and may help explain why the
dinosaurs became extinct.
Because the specimen is so valuable to science,
everything was done to facilitate the excavation while maintaining the
integrity of the fragile Badlands. The Bureau of Land Management (BLM)
worked closely with paleontologists from the New Mexico Museum of Natural
History and Science (NMMNHS) to best minimize the impact on the land, and
ensure that the excavation site was returned to its original condition.
Because the area couldn’t be reached by motor vehicles, paleontologists
and volunteers camped about two miles from the sites and hiked in each
day, carrying their materials and tools.
In addition to being scientifically important, the
skeleton will have great public educational value. Once studied, it will
go on display at the NMMNHS in Albuquerque. Work proceeds slowly so as not
to damage the specimen. Upon completion of study the specimen will be put
on display at the museum sometime in 2001.
Dr. Tom Williamson, Curator of Paleontology, NMMNHS,
in cooperation with the BLM lead the excavation of the specimen. Dr.
Williamson was assisted by a group of volunteers affiliated with the
museum, BLM wilderness specialists, Chris Barns and Richard Simmons, and
BLM’s regional paleontologist, Mike O’Neill.
The Bisti Badlands are public lands administered by
the BLM. The Blackhawk helicopter was provided by the Army National Guard,
and the semitrailer and tractor were provided by the federal Bureau of
Indian Affairs’ Southern Ute Agency in Colorado. |
