The Chicxulub impact predates the K/T mass extinction
The dinosaurs could not have been killed by the meteorites 65Kyrs ago because there is evidence that there were life after the supposed time that the the metheorites hit the earth.

Methods
This study examines several minerals and found evidences of planktic foraminiferal assemblages in the minerals. This indicates that there were still life even after the Chicxulub occurred. They also studied five proxies that demonstrated that the the Chicxulub impact predates the K/T boundary by about 300,000 years and could not have caused the mass extinction.

Results
The presence of certain minerals associated with certain layers of rock indicated that there were planktic foraminiferal remains, demonstrating that certain life, including fragile species, continued after the Chicxulub impact. Therefore, the meteor may have affected life forms, but it did cause a mass extinction. The evidence proves that life continued for 300,000 years after this incident.
