The site provides new information about the
region's sauropods, which were previously known only from fragments
of a tail bone, a leg bone, and a few bits
of teeth — scraps so small that researchers couldn't assign the fossils to a
particular species or even estimate its
size.
But you can use other ideas for the
size of a
region, and in
particular, you can use the probability
of the
region under some prior distribution.
