I was using chunkbase dot com and entered -19118191491 and by the map I see every biome within the few thousand blocks if fully zoomed out chunkbase dot com says it's for Java versions 1.9 and up so I dunno if the latest snapshot 1.12.2 fits in that category, btw the seed is not random there was a formula I used when making it and not mathematical either, I based it off my name let me know what you find in it but yeah there is every known biome that I at least know of just within a few thousand blocks! Not sure though if there is Ocean Monument in this area, or Mineshafts, or Multiple Villages, or Stronghold nearby? But that's up for you to explore and find out, I was just hunting for a seed that had everything Biome based at the least and I have found it
