When looking arround I found: https://www.wired.com/2011/05/oldest-fossil-micrometeorites/

"To get to the roughly 300 micrometeorites, Onoue’s team crushed and sieved the rock, cleaned it with ultrasonic waves, then ran a magnet over the material. Under an electron microscope, they found 10-micron-wide spheres that somehow survived descent through Earth’s atmosphere, chemical weathering and 240 million years of punishing fossilization."

Maybe they should use a different method to get those meteorites out of the rock. Not that they create more of them :)

I suggest that it would be a convenience to your viewers if you link the Remote View to the associated YouTube videos.
