The "gotcha" with the C14 is described here: https://answersingenesis.org/fossils/dating-dilemma-fossil-wood-in-ancient-sandstone/
Does anyone know more about what these idiots are up to, and able to give a better response to explain that these results are not scientific proof of anything except the inability of Creationists to apply correct methods.
I see the cleverness of the 'Gotcha', it takes advantage of notions of simplistic understanding of science. Trying to explain to lay-persons the intricacies of these methods is difficult, and I am out of date myself with my geology!
Young earth creationists know these points and know they are lying, but that doesn't stop them from doing so. Their religion is at stake.
