re: hybodonts at K/T correction

Sorry, sent last message when I meant to abort.
On hybodonts at the K/T boundary: their range virtually but not absolutely
ends at the Maastrichtian (not as I posted Campanian) with loss of the
common genus Lissodus.  But, they persisted until the Paleocene: thus,
the K/T event had effectively no influence on them.  A point to consider
(a declining group unaffected by the apparent chaos).
