Rome, Italy (AP) Italian paleontologists said yesterday
they have identified a new species of dinosaur, which lived 200 million years
ago and is one of the oldest meat-eating reptiles ever discovered.
According to fossil fragments found in a quarry in northern
Italy the dinosaur was 26.4 foot long, had a long neck and weighed over a ton,
Giorgio Teruzzi, supervisor of palontology at Milan's Museum of Natural History,
told the Associated Press. Each of it's sharp teeth measured 2 and 8/10 inches
long, he said.
It is believed to have lived in the early Jurassic era, usually
associated with more primitive forms of carnivorous dinosaurs. The Jurassic
era lasted from 140 million to 208 million years ago.
"It is the world's oldest three fingered dinosaur, and one of
the oldest overall," one of the researchers, Cristiano Dal Sasso, said in an
interview.
The dinosaur, tentatively called saltriosaur after the name
of the quarry where the fossils were found, is very similar to another predator,
the American allosaur, but is believed to be 20 million years older.
"What's interesting about this dinosaur is that it is more specialized,
it is closely related to the more advanced species," said Thomas R. Holtz, a
paleontologist at the department of Geology at the University of Maryland at
College Park.
The fossils were found entombed in a limestone block in a quarry
in Saltrio, north of Milan, in 1996. Researchers started studying them only
last year.
Holtz said that 200 million years ago was a critical time for
the evolution of meat-eating dinosaurs. It was then that they started evolving
into truly fierce predators.
The saltriosaur fossils will go on display next week at natural
history museums in both Milan and Besano, near the quarry.
