Berkeley Researchers Make Startling Dinosaur Discovery BERKELEY,
Calif., Jul. 19, 2007 (KGO) (KGO) -- Some U.C. Berkeley
paleantologists have made a startling dinosaur discovery. What
they've found in New Mexico will change the way scientists think
about dinosaurs and the world they lived in, and perhaps other
species as well. Video shot by U.C. Berkeley researchers shows
the excavation site in northern New Mexico. The area is called
Ghost Ranch, and in a small, 20-by-10-foot site, paleontologists
are discovering ghosts of dinosaurs and their ancestors living
together about 215 million years ago. Until now, there has never
been evidence of all these different generations living together
at the same time. Randy Irmis, U.C. Berkeley: "This has some
impact on how we interpret the origin and early diversification
of the dinosaurs. It shows they did not quickly replace or out-
compete other animals." U.C. Merced paleontologist Matt Wedel
has worked with the researchers in New Mexico. He showed ABC7
