[The dinosaur-killing Chicxulub meteor might have ignited an oilfield rather than forests when it slammed into the Gulf of Mexico 65 million years ago, say geologists.

Smoke-related particles found in sediments formed at the time of the impact are strikingly similar to those created by modern high-temperature coal and oil burning, as opposed to forest fires...]

I'm not going to push this, since I'm sure I'm over-reaching, but ...

When they find material which is often taken as evidence of human activities, and when that evidence seems to be from 65 million years ago, does that suggest in anyway that the dating methods may be off?

One of the classic retorts against Creationism or ID is "If we find homo sapiens in a coal bed, maybe we'll rethink the dating, but that has never happened."

Well ...
