Raw Prime Meat spoils quickly, so keep it in a fast flyer or another creature with preservation benefits until you need it. Hunt alpha creatures, Argentavis, titanoboas, paracers, diplodocus, stegos, or sarcos, using a strong mount and suitable harvesting tool for better results. Flyers can help locate and safely farm prime-bearing creatures, while high-level carnivores can clear dense areas efficiently. Breeding and harvesting baby creatures is another effective but morally controversial option, especially for quickly preparing carnivore tames.
