Notes on fossils

Introduction:

1. Gen I: Kabuto-line and Omanyte-line, Aerodactyl
2. Gen II: None.
3. Gen III: Anorith-line and Lileep-line
4. Gen IV: Cranidos-line and Shieldon-line
5. Gen V: Tirtouga-line and Archen-line
6. Gen VI: Amaura-line and Tyrunt-line, Mega Aerodactyl
7. Gen VII: None.

Looking at this we can predict something like this:

Gen VI: 521 and 521

Gen IX: 521 and 521 

Gen X: 521 and 593

Gen XI: 547 and 547, new Archeops forme?

Gen XII: N/A

Gen XIII: 547 and 547

Gen XIV: 547 and 547

Gen XV: 547 and 619

Gen XVI: 573 and 573, new 593 forme?

Gen 17: n/a

Gen 18: 573 and 573

Gen 19: 573 and 573

Gen 20: 573 and 645

Gen 21: 599 and 599

Gen 22: n/a

Gen 23: 599 and 599

Gen 24: 599 and 599

Gen 25: 599 and 671

Gen 26: 625 and 625

Gen 27: n/a

Gen 28: 625 and 625

Gen 29: 625 and 625

Gen 30: 625 and 699

Gen 31: 651 and 651

Gen 32: n/a

Gen 33: 651 and 651

Gen 34: 651 and 651

Gen 35: 651 and 723

Gen 36: 677 and 677

Gen 37: n/a

Gen 38: 677 and 677

Gen 39: 677 and 677

Gen 40: 677 and 749

Gen 41: 703 and 703

Gen 42: n/a

Gen 43: 703 and 703

Gen 44. 703 and 703

Gen 45: 703 and 775

Gen 46: 729 and 729

So, it would take roughly 39 years for fossils to reach to Black Kyurem levels. At that point there would be 49 families.
