Has anybody ever passed this many at once? Any clue what kind they might be?

I'm pretty deep into the kidney stone journey at this point, and I call it the "family curse" (we've allllll had problems with UTIs and kidney stones, infections, etc.) - but somehow I feel like I got the worst end of it. The photos are from my first big time about 2 years ago - just wondering if anyone has ever passed this many at once and/or if you know what type they might be? I never pass just one stone lol, it's always multiple small ones, but this batch in the pics was the most extreme of all of them.
