We dont have alot of problems coming up with camera trap or iphone photos. Or plaster foot, hand, butt or body casts or unidentified hairs uncut and lacking a medulla.........thats not the problem. Thats called evidence.......which cannot rule out misidentification or hoax.
The problem is that none of that is considered solid PROOF. Big difference!
Which nullifies many layman researchers methods because they are out there with a camera and dental resin.
We need a body, part there of, a fossil (to at least prove an extant species IS possible) or somebody needs to get lucky with some sort of passive collection of DNA.
