Future Fossils?

Hail landed in the mud and melted about 18 hours before this photo, leaving well-defined impressions which quite accurately documented the size of the hailstones. This sort of record, when available, certainly beats the usual overestimates of hail size provided by excited spotters who seldom witness (and even more seldom measure) large hail. Perhaps, somewhere in the world, semi-spheric cavities have been found at a constant level atop some fossilized mudstone layer; and if so, that could be the oldest hailstorm record in existence. It's meteorological geology!
