I thought to donate the fossils, you had to talk to that one lady in the cleaning room, but when I have fossils and I talk to her, she just asks what I want to trade my donation points in for. There's no option to donate. Help!!!!
Okay bro, here's the explanation. When you donate a fossil (and in champions, vivosaurs too) you've basically gotten a lower score than last time on it, and it will be automatically given to the fossil donor society thingy in exchange for donation points. if you get 125-100 points (a perfect on a regular, and 125 if you already got a maximum), then it'll be donated for 10 points, if you get 99-90, then it's 5 points 89-80, 4 points 79-70, 3 points 69-60, 2 points, and 59-50, a single point anything below 50 is (obviously) a failure.
let's say you scored 100 on a spinax skull, and you clean another and damage it by 1. then you'd get 5 donation points. but let's say you get a red spinax fossil and clean it perfectly, then it'd be intergrated into spinax.
