Talk about beating a dead horse; haven't heard much about the "3 m gap"
since the late 1980s!!
However, the paper doesn't address an observed phenomenon (the apparent loss
of various lineages of western American dinosaur taxa during the
Maastrichtian), which is a separate issue from a decline in the uppermost
few meters of the latest Maastrichtian.
