old world type "big" mesa and extreme hills biome

[Vegito72]

So, i was going through mcpe old worlds using 0.15.0 in the seed with random numbers and letters after them, and in the seed 2079884116 on old world type
in this world you spawn in a plains biome but if you do a 360 you will see 2 mesa biomes, one with clay mountains and one with redsand and cactus, However since it is an old world type caves dont generate so above ground mineshafts aren't existant in this seed
in corners on the map there are extreme hill biomes which means emeralds
The wood available in this seed is sadly only oak and Birchwood
you might be thinking "what about diamonds? I just read that there are no caves so how am i going to find diamond?" Well i have done the math (i did this math long ago) 3-8 diamonds spawn in a single chunk in
so there are somewhere between 768 and 2048 diamonds in a "old" sized world as for the cave thing dig under y13

I forgot what i was going to put while checking if that math was still correct so I'm just going to put screen shots:

seed:
2079884116
(The world generation of old and infinite are way different so if you put this seed with the world generation set to infinite you will get a different world then the one i was typing about
ALSO This seed is on 0.14.3 so it might not work on future updates)
