Sorry, this is a few days old. I just found it. I'm gutted!

Scientists have discovered that the original statistical model used to calculate dinosaur mass is flawed, suggesting dinosaurs have been oversized.
...
"Paleontologists have for 25 years used a published statistical model to estimate body weight of giant dinosaurs and other extraordinarily large animals in extinct lineages. By re-examining data in the original reference sample, we show that the statistical model is seriously flawed and that the giant dinosaurs probably were only about half as heavy as is generally believed" says Gary Packard from Colorado State University.
"The original equation used by scientists produces fairly accurate results when determining the mass of smaller animals, but when used on larger animals our research shows that many errors have occurred," says Geoffrey Birchard, associate professor of environmental science and policy at George Mason University who was involved with the research. "The new equation shows that dinosaurs are much smaller than we thought, but there is no mistaking that they were indeed huge animals."

And in case, like me, you were wondering if their fossilized bones had expanded:

According to Birchard, this new research suggests that some dinosaurs were much more slender than had been thought.
