RE: First fossils of Tyrannosaurus (as Dynamosaurus) to be displayed at British Natural History Museum
Claims of Laramidian isolation in the Maastrichtian are STRONGLY
exaggerated. It is better to think of Laramidia as a peninsula of
Asiamerica rather than its own landmass, given the faunal similarities
between mesic communities of Asia and of Laramidia.
That said, our knowledge of latest Maastrichtian faunas of eastern Asia
are really, really less than it could be. There are some tantalizing
sites, but at present nothing which produces the quality of fossils that
the Hell Creek does.
Them's the break. Nature is not obliged to give us outcrops at the times
and places we really want to have them.
