Short of finding dinosaur bones with fragments of meteorites embedded in
them, there is no way to show that any particular dinosaur died as a result
of an impact. However, there has been at least one passing reference in the
serious research journals that has come close to making a similar claim as the
claim you made (so don't be too hard on yourself!). Except, it wasn't
a dinosaur getting damaged by a killer meteorite, it was a poor
cephalopod (a mollusk) that purportedly got bonked by a rock from space.
I don't happen to believe that the ceph. got bonked by the meteorite (it
seems more likely that the cephalopod was already dead on the sea bottom, and
the meteorite settled on top of it).
At any rate, read all about it in:

in fossiliferous limestone from Brunflo, central Sweden.
