You need to dig into Fassett's paper a little but essentially he has found hadrosaurid dinosaur fossils in rock that is around half a million years younger than the K-T boundary asteroid impact. He is confident that the fossils are not the result of re-worked sediment (i.e. older rock, that contained dinosaur bones, that has been eroded and re-deposited making it appear to be younger than it is). If he is right then the Chicxulub asteriod impact crater did not wipe out all of the non-avian dinosaurs. They lived on for at least half a million years, albeit in drastically reduced numbers.
Ah who mentioned Nessie. Since it is almost the tourist season I want to be first to say that I spotted a very lifelike dinosaury type thing somewhere in Scotland. So all you tourists get here quick or you might miss it.
