The larger and older a crater is, the less likelihood there are surviving
meteorites found. "Older" is understood owing to weathering. Larger is owing
that when such vast amount of kinetic energy gets converted to heat bonds will
be sheered at the molecular and atomic level. So very little remains.

 Be it remembered in the case of Canyon Diablo , which may really be a
splintered sister swarm off the meteor crater impactor: It has been estimated
somewhere that 99.99% of that impactor was turned into a metallic fog some of
which condensed into the spheroids.--Literally vaporized and a very hot vapor at
that.

PS: The recovery of a single OC micro fragment in the ocean 65my after Chuxilub
is unconvincing that it was a meteorite from that event. So let me preempt any
suggestion that Chuxilub is a crater with meteorites.
