RE: thumbnails in fatigue fracture
Once the fatigue progresses far enough that the remaining area cant carry the load the rest will fail in tensile overload.

No. Stress corrosion cracking (SCC) can provide a similar appearance on a fracture surface.
To add to edstainless's comment above, the thumbnail typically is evidence of where the crack started.
