I dont know about you guy but for me on mobile, i use a high lv pter (my lv 200+) fly and kill anything that drop prime meat, then just use barrel roll attack to harvest the prime meats, it worked for me everytime, usually i get about 2-6 prime meat which is a good amount, so now mobile user dont have to brutaly murder baby dino

I do not know if it work on console nor pc so if you using one of those, plz try and give the result
