I've seen fossilized spark plugs. Actual stone surrounding a plug. The stone was quite a bit older than the the plug, of course.
>>Actually, it would not. They’ve already found multiple sites where older layers are above new layers. This is due to earthquakes, volcanoes, erosion, and other natural events that move the earth around.<<
I was using a broad example of how TToE is falsifiable. If you were have a validated and verified modern horse skeleton where it does not below based on the period of its burial, you would have falsified TToE.
That is the point, not the technical details.
