The
fact that bones have curves has now thrown a curveball into calculations of
dinosaur weight, researchers say.
New
estimates suggest dinosaurs may have been lighter than once thought, scientists
explain.
With
the rare exceptions of fossilized scraps of skin, feathers, bristles and
other relatively soft tissues, all that remains of most extinct creatures are
their skeletons. One way that investigators seek to learn more about these lost
animals is to deduce their weight from their bones.
