DANIA BEACH, Fla. (AP) MARCH
18, 05:31 EST — Researchers have unveiled what may be the most
convincing evolutionary link yet between dinosaurs and birds: a 75
million-year-old creature with a roadrunner's body, arms that resembled
clawed wings and hair-like feathers.
They call it bambiraptor
feinbergi.
The first recovered skeleton
of the species was shown Thursday by the Florida Institute of
Paleontology. It is not clear whether the creature could fly, but experts
said that anatomically it is the most bird-like dinosaur yet discovered.
They said the finding advances the increasingly popular theory that birds
evolved from dinosaurs.
Bambiraptor's skeleton was
discovered in 1994 by 14-year-old Wes Linster, who was hunting for fossils
near Glacier National Park in northern Montana.
More than 95 percent of the
warm-blooded carnivore's bones were recovered. Scientists are usually
ecstatic to recover 30 percent of a dinosaur's skeleton.
"This
species is truly a dinosaur Rosetta stone,'' said Martin Shugar, the
institute's director, referring to the tablet found 200 years ago that
helped archaeologists decipher Egyptian hieroglyphics.
The skeleton will be
exhibited at the Graves Museum of Archaeology & Natural History, where
the institute is based. Shugar persuaded Michael Feinberg, a Hollywood,
Fla., investor and philanthropist, to buy the specimen for an undisclosed
price and lend it to the museum.
Linster christened the
specimen bambiraptor because it's small like Bambi. The feinbergi was
added later to honor Feinberg.
John Ostrum, a Yale
University professor and one of the world's leading paleontologists,
examined the skeleton and likened it to the Mona Lisa. "I have never
seen any specimen as complete as that and I have collected all over the
world,'' he said.
Ostrum said bambiraptor has
several traits usually found in birds, such as a wishbone instead of a
full breastbone and avian-like arm bones.
About 3 feet long and
weighing 7 pounds, bambiraptor lived in a sparsely forested area in what
is now Montana at a time when the Rocky Mountains were just beginning to
rise, said David A. Burnham, a University of Kansas paleontologist who
assembled the skeleton.
It would have preyed on
small mammals and reptiles, using its teeth, sharp talons and whip-like
18-inch tail to subdue its prey, said Burnham and Kraig Dertsler, a
University of New Orleans professor who helped study it.
It was fast, had a keen
sense of smell and the structure of its arms and its feathers may have
allowed it to fly, although more study must be done before that can be
concluded, Burnham and Dertsler said. |
