<P itxtvisited="1">In the study, published this week in the <I

of environmental science and policy at George Mason University, was part of a 
team which uncovered a problem with the statistical model used by some 
scientists in the dinosaur community to estimate the mass of <A class=textTag

"The new equation shows that dinosaurs are much smaller than we thought, but there is no mistaking that they were indeed huge animals." </P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.physorg.com/news165147675.html"><P itxtvisited="1">The researchers developed a new equation for calculating dinosaur mass based on bone dimensions.
