 Manson struck in the Campanian c 74 Ma but is not
associated with any dinosaur extinction, not even in
North America. I note that Parasaurolophus is present
in the De-na-zin, dated at c 73 Ma, so Manson
apparently was not responsible for the waning of
lambeosaurs.

 With the exception of the latter I don't think the
correlation is considered very good.
