For example, Stonehenge suddenly became older than the Pyramids, instead of younger.
And, we can date things that have been dated by some other method.In the 70's: If this sort of thing interests you, you should find the journal Radiocarbon and read one of the issues devoted to calibration.For example, see Radiocarbon 46,1029 (2005), which has a calibration curve that goes back 26,000 years.Historians don't have "right answers" for really old things.However, carbon dating has done well on young material like the Dead Sea Scrolls, the Minoan ruins, and acacia wood from the tomb of the pharoah Zoser.Then, we have wood for which we know the right answer.
So, carbon dating has been calibrated against the rings of California bristlecone pines, and Irish bog oaks, and the like.
The C14 will undergo radioactive decay, and after 5730 years, half of it will be gone. So, if we find such a body, the amount of C14 in it will tell us how long ago it was alive. The method doesn't work on things which didn't get their carbon from the air.
This leaves out aquatic creatures, since their carbon might (for example) come from dissolved carbonate rock.
Some were done by finding lakes with atmospherically derived carbon in their annual layers of silt (called varves).
In those particular lakes, the varves can be counted, and the varves can also be carbon dated. The first kind are datings of things that should't be carbon dated.
It is also standard to coat fossils during their extraction and transport.
