This proves that some dinosaurs were around shortly before the Chicxulub impact. But it does not mean that there were not aready in serious decline. Nor, indeed, does it mean that some did not survive the impact.
I would not be all surprised if one day we find post-Chicxulub remains.
Though of course, we do not exactly have precise dating for fossils this old and at best there's an error margin of several tens of thousand years.
Forgive me if this is a stupid question, I don't know much about this.
If an asteroid, large enough to cause world wide extinction, hit the earth, and they claim to know where the crater is, why haven't they found the actual asteroid?
A 3D map of local gravity and magnetic field variations reveals the Chicxulub crater, now buried beneath tons of sediment. This view is looking down at the surface, from an angle of about 60°.
Are Present Deposition Rates the Key to the Past? The a priori assumption of many geologists is that the massive flat-lying, sheet-like, sedimentary deposits which are stacked, one upon the other, and found throughout the world took hundreds of millions of years to deposit. Such a hypothesis is known as uniformitarianism; however, it is inadequate to account for much, if not most, of the fossil-bearing strata. Some people, who pride themselves as truth-seekers, seem to think that they must, at all costs, force-fit their conclusions so that they always fall into an evolution-based / semi-uniformitarian / Old Earth philosophy. Others pretend as if they won the debate long ago with regard to how we arrived on Earth, and that it should "hereafter never... be questioned". 15
Unfortunately for the cause of science, this has resulted in an almost paranoia of writing anything that remotely resembles a catastrophic viewpoint. For to do so might subject one to ridicule, risk alienating colleagues, and perhaps endanger one's very career in the field of evolutionary thought - also often referred to as "science." In other words, an evolutionary view, no matter how unscientific it may be, is the only opinion that will be tolerated when discussing our origins. Therefore an Old Earth is absolutely essential, and those who challenge it are often labeled enemies of "science," or "religious" fanatics in an attempt to quickly dismiss the data, and the debate, no matter how valid the contrary evidences may be. For if the Time-curtain is lifted all can (and likely will) see that the evolutionary house must be torn down -- leaving the entire scientific community with nothing at all to say regarding our origins, and therefore greatly reducing their priest-like positions of societal influence

This "proves" nothing, as usual. It is evidence, that MAYBE their THEORIES MIGHT BE CORRECT.

That's the thing I've always wondered about.
